Cave Johnson voice lines

This is a complete list of Cave Johnson's voice lines from Portal 2.

1952

 * [[Media:Cave Johnson fifties_intro03.wav|"Now, you already met one another on the limo ride over, so let me introduce myself."]]
 * [[Media:Cave Johnson fifties_intro04.wav|"I'm Cave Johnson. I own the place."]]
 * [[Media:Cave Johnson fifties_intro06.wav|"That eager voice you heard is the lovely Caroline, my assistant. Rest assured, she has transferred your honorarium to the charitable organization of your choice. Isn't that right, Caroline?"]]
 * [[Media:Cave Johnson fifties_intro07.wav|"She's the backbone of this facility. Pretty as a postcard, too. Sorry, fellas. She's married. To science."]]
 * [[Media:Cave Johnson fifties_intro06.wav|"That eager voice you heard is the lovely Caroline, my assistant. Rest assured, she has transferred your honorarium to the charitable organization of your choice. Isn't that right, Caroline?"]]
 * [[Media:Cave Johnson fifties_intro07.wav|"She's the backbone of this facility. Pretty as a postcard, too. Sorry, fellas. She's married. To science."]]


 * [[Media:Cave Johnson fifties_waiting01.wav|"There's a thousand tests performed every day here in our enrichment spheres. I can't personally oversee every one of them, so these pre-recorded messages'll cover any questions you might have, and respond to any incidents that may occur in the course of your science adventure."]]
 * [[Media:Cave Johnson fifties_waiting03.wav|"Your test assignment will vary, depending on the manner in which you have bent the world to your will."]]
 * [[Media:Cave Johnson fifties_waiting05.wav|"Those of you helping us test the repulsion gel today, just follow the blue line on the floor."]]
 * [[Media:Cave Johnson fifties_waiting07.wav|"Those of you who volunteered to be injected with praying mantis DNA, I've got some good news and some bad news."]]
 * [[Media:Cave Johnson fifties_waiting08.wav|"Bad news is we're postponing those tests indefinitely. Good news is we've got a much better test for you: Fighting an army of mantis men. Pick up a rifle and follow the yellow line. You'll know when the test starts."]]


 * [[Media:Cave Johnson fifties_elevator_out_a01.wav|"They say great science is built on the shoulders of giants. Not here. At Aperture, we do all our science from scratch. No hand holding."]]

1953

 * [[Media:Cave Johnson fifties_repulsion_intro02.wav|"Alright, let's get started. This first test involves something the lab boys call 'repulsion gel.'"]]
 * [[Media:Cave Johnson fifties_repulsion_intro03.wav|"You're not part of the control group, by the way. You get the gel. Last poor son of a gun got blue paint. Hahaha. All joking aside, that did happen - broke every bone in his legs. Tragic. But informative. Or so I'm told."]]


 * [[Media:Cave Johnson fifties_second_test_intro01.wav|"The lab boys just informed me that I should not have mentioned the control group. They're telling me I oughtta stop making these pre-recorded messages. That gave me an idea: Make more pre-recorded messages. I pay the bills here, I can talk about the control group all damn day."]]


 * [[Media:Cave Johnson misc_tests02.wav|"For this next test, we put nanoparticles in the gel. In layman's terms, that's a billion little gizmos that are gonna travel into your bloodstream and pump experimental genes and RNA molecules and so forth into your tumors."]]
 * [[Media:Cave Johnson misc_tests03.wav|"Now, maybe you don't have any tumors. Well, don't worry. If you sat on a folding chair in the lobby and weren't wearing lead underpants, we took care of that too."]]


 * [[Media:Cave Johnson fifties_second_test_complete03.wav|"Oh, in case you got covered in that repulsion gel, here's some advice the lab boys gave me: DO NOT get covered in the repulsion gel."]]
 * [[Media:Cave Johnson fifties_second_test_complete02.wav|"We haven't entirely nailed down what element it is yet, but I'll tell you this: It's a lively one, and it does NOT like the human skeleton."]]

1957

 * [[Media:Cave Johnson misc_tests08.wav|"All these science spheres are made of asbestos, by the way. Keeps out the rats. Let us know if you feel a shortness of breath, a persistent dry cough or your heart stopping. Because that's not part of the test. That's asbestos."]]
 * [[Media:Cave Johnson misc_tests10.wav|"Good news is, the lab boys say the symptoms of asbestos poisoning show a median latency of forty-four point six years, so if you're thirty or older, you're laughing. Worst case scenario, you miss out on a few rounds of canasta, plus you forwarded the cause of science by three centuries. I punch those numbers into my calculator, it makes a happy face."]]


 * [[Media:Cave Johnson fifties_into_middle_of_test01.wav|"Ha! I like your style. You make up your own rules, just like me."]]
 * [[Media:Cave Johnson fifties_into_middle_of_test02.wav|"Bean counters said I couldn't fire a man just for being in a wheelchair. Did it anyway. Ramps are expensive."]]


 * [[Media:Cave Johnson misc_tests07.wav|"Just a heads-up: That coffee we gave you earlier had fluorescent calcium in it so we can track the neuronal activity in your brain. There's a slight chance the calcium could harden and vitrify your frontal lobe. Anyway, don't stress yourself thinking about it. I'm serious. Visualizing the scenario while under stress actually triggers the reaction."]]

1958

 * [[Media:Cave Johnson misc_tests26.wav|"Now, if you're part of Control Group Kepler-Seven, we implanted a tiny microchip about the size of a postcard into your skull. Most likely you've forgotten it's even there, but if it starts vibrating and beeping during this next test, let us know, because that means it's about to hit five hundred degrees, so we're gonna need to go ahead and get that out of you pretty fast."]] Note: the game files say "Control Group Seven-Dee" instead.


 * [[Media:Cave Johnson fifties_fourth_test_complete01.wav|"I'm telling 'em, keep your pants on."]]
 * [[Media:Cave Johnson fifties_fourth_test_complete02.wav|"Alright, this next test may involve trace amounts of time travel. So, word of advice: If you meet yourself on the testing track, don't make eye contact. Lab boys tell me that'll wipe out time. Entirely. Forward and backward! So do both of yourselves a favor and just let that handsome devil go about his business."]]


 * [[Media:Cave Johnson fifties_fifth_test_intro01.wav|"If you're hearing this, it means you're taking a long time on the catwalks between tests. The lab boys say that might be a fear reaction."]]
 * [[Media:Cave Johnson fifties_fifth_test_intro03.wav|"I'm no psychiatrist, but coming from a bunch of eggheads who wouldn't recognize the thrill of danger if it walked up and snapped their little pink bras, that sounds like 'projection'."]]
 * [[Media:Cave Johnson fifties_fifth_test_intro06.wav|"THEY didn't fly into space, storm a beach, or bring back the gold. No sir, we did! It's you and me against the world, son! I like your grit! Hustle could use some work, though. Now let's solve this thing!"]]


 * [[Media:Cave Johnson fifties_fifth_test_complete09.wav|"Science isn't about WHY. It's about WHY NOT. Why is so much of our science dangerous? Why not marry safe science if you love it so much. In fact, why not invent a special safety door that won't hit you on the butt on the way out, because you are fired."]]
 * [[Media:Cave Johnson fifties_fifth_test_complete03.wav|"Not you, test subject, you're doing fine."]]
 * [[Media:Cave Johnson fifties_fifth_test_complete08.wav|"Yes, you. Box. Your stuff. Out the front door. Parking lot. Car. Goodbye."]]

1959

 * [[Media:Cave Johnson fifties_outro02.wav|"Congratulations! The simple fact that you're standing here listening to me means you've made a glorious contribution to science."]]
 * [[Media:Cave Johnson fifties_outro05.wav|"As founder and CEO of Aperture Science, I thank you for your participation and hope we can count on you for another round of tests."]]
 * [[Media:Cave Johnson fifties_outro07.wav|"We're not gonna release this stuff into the wild until it's good and damn ready, so as long as you keep yourself in top physical form, there'll always be a limo waiting for you."]]
 * [[Media:Cave Johnson fifties_outro08.wav|"Say goodbye, Caroline."]]
 * [[Media:Cave Johnson fifties_outro09.wav|"She is a gem."]]

1971

 * [[Media:Cave Johnson seventies_intro16.wav|"Greetings, friend. I'm Cave Johnson, CEO of Aperture Science - you might know us as a vital participant in the 1968 Senate Hearings on missing astronauts. And you've most likely used one of the many products we invented. But that other people have somehow managed to steal from us. Black Mesa can eat my bankrupt--"]]
 * [[Media:Cave Johnson seventies_intro02.wav|"Right. Now, you might be asking yourself, 'Cave, just how difficult are these tests? What was in that phone book of a contract I signed? Am I in danger?'"]]
 * [[Media:Cave Johnson seventies_intro04.wav|"Let me answer those questions with a question: Who wants to make sixty dollars? Cash."]]
 * [[Media:Cave Johnson seventies_intro06.wav|"You can also feel free to relax for up to 20 minutes in the waiting room, which is a damn sight more comfortable than the park benches most of you were sleeping on when we found you."]]
 * [[Media:Cave Johnson seventies_intro14.wav|"So. Welcome to Aperture. You're here because we want the best, and you're it. Nope. Couldn't keep a straight face."]]
 * [[Media:Cave Johnson seventies_intro15.wav|"Anyway, don't smudge up the glass down there. In fact, why don't you just go ahead and not touch anything unless it's test related."]]

1972

 * [[Media:Cave Johnson seventies_test_a_intro01.wav|"The testing area's just up ahead. The quicker you get through, the quicker you'll get your sixty bucks."]]
 * [[Media:Cave Johnson seventies_test_a_intro02.wav|"Caroline, are the compensation vouchers ready?"]]


 * [[Media:Cave Johnson seventies_test_a_complete06.wav|"Great job, astronaut, war hero, and/or Olympian! With your help, we're gonna (tape sped up) change the world!"]]
 * [[Media:Cave Johnson seventies_test_a_complete05.wav|"This on? [thump thump] Hey. Listen up down there. That thing's called an elevator. Not a bathroom."]]

1976

 * [[Media:Cave Johnson seventies_test_b_complete01.wav|"If you're interested in an additional sixty dollars, flag down a test associate and let 'em know. You could walk out of here with a hundred and twenty weighing down your bindle if you let us take you apart, put some science stuff in you, then put you back together good as new."]]


 * [[Media:Cave Johnson seventies_test_b_complete03.wav|"In case you're interested, there's still some positions available for that bonus opportunity I mentioned earlier. Again: All you gotta do is let us disassemble you. We're not banging rocks together here. We know how to put a man back together."]]
 * [[Media:Cave Johnson seventies_test_b_complete04.wav|"So that's a complete reassembly. New vitals. Spit-shine on the old ones. Plus we're scooping out tumors. Frankly, you oughtta be paying us."]]

1978

 * [[Media:Cave Johnson seventies_outro01.wav|"Thank you - I can't believe I'm thanking these people  - for staggering your way through Aperture Science's propulsion gel testing. You've made some real contributions to society for a change, and for that, humanity is grateful."]]
 * [[Media:Cave Johnson seventies_outro02.wav|"If you had any belongings, please pick them up now. We don't want old newspapers and sticks cluttering up the building."]]
 * [[Media:Cave Johnson seventies_intro07.wav|"For many of you, I realize 60 dollars is an unprecedented windfall, so don't go spending it all on... I don't know. Caroline, what do these people buy? Tattered hats? Beard dirt?"]]

1981

 * [[Media:Cave Johnson eighties_intro01.wav|"Welcome to the enrichment center. [cough]"]]
 * [[Media:Cave Johnson eighties_intro03.wav|"Since making test participation mandatory for all employees, the quality of our test subjects has risen dramatically. Employee retention, however, has not."]]
 * [[Media:Cave Johnson eighties_intro04.wav|"[cough] As a result, you may have heard we're gonna phase out human testing. There's still a few things left to wrap up, though."]]
 * [[Media:Cave Johnson eighties_intro07.wav|"The bean counters told me we literally could not afford to buy seven dollars worth of moon rocks, much less seventy million. Bought 'em anyway. Ground 'em up, mixed em into a gel."]]
 * [[Media:Cave Johnson eighties_intro08.wav|"And guess what? Ground up moon rocks are pure poison. I am deathly ill."]]
 * [[Media:Cave Johnson eighties_intro10.wav|"Still, it turns out they're a great portal conductor. So now we're gonna see if jumping in and out of these new portals can somehow leech the lunar poison out of a man's bloodstream. When life gives you lemons, make lemonade. [coughs] Let's all stay positive and do some science."]]
 * [[Media:Cave Johnson eighties_intro12.wav|"That said, I would really appreciate it if you could test as fast as possible. Caroline, please bring me more pain pills."]]

1982

 * [[Media:Cave Johnson eighties_outro09.wav|"All right, I've been thinking. When life gives you lemons? Don't make lemonade. Make life take the lemons back! Get mad! 'I don't want your damn lemons! What am I supposed to do with these?'"]]
 * [[Media:Cave Johnson eighties_outro11.wav|"Demand to see life's manager! Make life rue the day it thought it could give Cave Johnson lemons! Do you know who I am? I'm the man who's going to burn your house down! With the lemons! I'm going to get my engineers to invent a combustible lemon that burns your house down! [cough]"]]
 * [[Media:Cave Johnson eighties_outro02.wav|"The point is: If we can store music on a compact disc, why can't we store a man's intelligence and personality on one? So I have the engineers figuring that out now."]]
 * [[Media:Cave Johnson eighties_outro05.wav|"Brain Mapping. Artificial Intelligence. We should have been working on it thirty years ago. I will say this - and I'm gonna say it on tape so everybody hears it a hundred times a day: If I die before you people can pour me into a computer, I want Caroline to run this place."]]
 * [[Media:Cave Johnson eighties_outro06.wav|"Now she'll argue. She'll say she can't. She's modest like that. But you make her."]]
 * [[Media:Cave Johnson eighties_outro07.wav|"Hell, put her in my computer. I don't care."]]
 * [[Media:Cave Johnson eighties_outro08.wav|"Allright, test's over. You can head on back to your desk."]]

1952

 * [[Media:Cave Johnson misc_tests06.wav|"If you've cut yourself at all in the course of these tests, you might have noticed that your blood is pure gasoline. That's normal. We've been shooting you with an invisible laser that's supposed to turn blood into gasoline, so all that means is, it's working."]]


 * [[Media:Cave Johnson misc_tests14.wav|"If you need to go to the bathroom after this next series of tests, please let a test associate know, because in all likelihood, whatever comes out of you is going to be coal. Only temporary, so do not worry. If it persists for a week, though, start worrying and come see us, because that's not supposed to happen."]]


 * [[Media:Cave Johnson misc_tests24.wav|"Just a heads up: We're gonna have a superconductor turned up full blast and pointed at you for the duration of this next test. I'll be honest, we're throwing science at the wall here to see what sticks. No idea what it'll do. Probably nothing. Best-case scenario, you might get some superpowers. Worst case, some tumors, which we'll cut out."]]

1971

 * [[Media:Cave Johnson misc_tests25.wav|"If you're allergic to peanuts, you might want to tell somebody now, because this next test may turn your blood into peanut water for a few minutes. On the bright side, if we can make this happen, they're gonna have to invent a new type of Nobel Prize to give us, so hang in there."]]


 * [[Media:Cave Johnson misc_tests01.wav|"The average human male is about sixty percent water. Far as we're concerned, that's a little extravagant. So if you feel a bit dehydrated in this next test, that's normal. We're gonna hit you with some jet engines, and see if we can't get you down to twenty or thirty percent."]]


 * [[Media:Cave Johnson misc_tests28.wav|"All right. We're working on a little teleportation experiment. Now, this doesn't work with all skin types, so try to remember which skin is yours, and if it doesn't teleport along with you, we'll do what we can to sew you right back into it."]]

Perpetual Testing Initiative

 * [[Media: Cave Johnson dlc2 0100 caveprime misc01.wav‎|"Welcome, test subject, it's Cave. Prime. From Earth One. I am speaking to you from across time and space! I am literally in the future! I am--Hold on... [off mic] What? [on mic] Alright, my assistant Greg tells me none of that's true. Got excited. You are the first test subject we have ever sent into a parallel universe, which apparently has nothing to do with time travel. Still exciting. Anyway, you should be seeing a test chamber in front of you. We designed it, those backwater universe yokels built it, and you're gonna test it. Remember: You gotta let us know if it WORKS or not, otherwise you're wasting everybody's time on two earths. Alright, get to it."]]


 * [[Media: Cave Johnson dlc2 0200 caveprime misc02.wav|"Cave here. Just so you know, this mic isn't two way. Can't hear a damn thing you're saying, so don't waste any oxygen trying to talk. [off mic] What? [on mic] My assistant Greg says some of these alternate Earths may not have oxygen. The air might be nitrogen or methane or, hell, everybody's head might be inside out. So just take little itty bitty breaths and if anybody asks you why your head's inside out, remember it's only inside out from their perspective, and you're fine. Head-wise. Trouble-wise, you're in a lot of it and you should probably run. Alright, enough hypotheticals. Let's test this test!"‎]]


 * [[Media: Cave Johnson dlc2 0300 caveprime misc03.wav‎|"Cave here. Man oh man. Wow. Greg's multiple universe theory was dicey, but you're pulling through with flying colors. We're all very proud of Greg. [pause] Oh, and you."]]


 * [[Media: Cave Johnson dlc2 0310 altcave sentientcloud01.wav‎|"Before we start testing today, let's have our mandatory minute of silence in honor of Earth's governing body, the Sentient Cloud. [throat clear] Starting now. [a pause] [coughing] [a longer pause] [more coughing] [still more pausing] Good, right. All hail the sentient cloud. Begin testing."]]


 * [[Media: Cave Johnson dlc2 0311 altcave sentientcloud03.wav|"I've just been notified that one of our test subjects may have angered the Sentient Cloud by beginning testing early. Now, as you all know, the cloud has banned all camera technology--hates getting its picture taken. So this'll have to be on the honor system: Will whoever started testing early please go outside so they can be consumed by the Cloud."‎]]


 * [[Media: Cave Johnson dlc2 0312 altcave sentientcloud04.wav|"Just a heads-up that the Cloud's still waiting. I don't think that thing's gonna go away, so somebody might wanna get out there."‎]]


 * [[Media: Cave Johnson dlc2 0313 altcave sentientcloud05.wav|"No! No! It came in under the door! It's leeching off all my skin! Aghhhhh- [click] Excerpt there from one of our safety videos. Grisly stuff, very informative. Somebody doesn't get out there soon we're gonna have to do a lottery, because believe me, if we keep that cloud waiting much longer he's coming in under the doors, and he will leech off all of our skin."‎]]


 * [[Media: Cave Johnson dlc2 0400 caveprime misc04.wav|"Cave here. The real Cave. Greg's been crunching some numbers here on Earth Prime. Turns out, the likelihood of me being the only Cave who likes talking to test subjects is-- [off mic] What's the actual number, Greg? [on mic] Right. Zero. So tell you what, we're gonna use a code word. If I say chariots, it means you're listening to me. Otherwise, it's an imposter Cave. I want you to know, you have a license to kill on this one. [off mic] What? [on mic] Greg says that might destroy the entire multiverse. Point is, use your own judgement. [fast, intimate] License-to-kill."‎]]


 * [[Media: Cave Johnson dlc2 0410 altcave mating ritual01.wav|"Welcome, gentlemen, to Aperture Rituals. Astronauts, war heroes, olympians: you're here because of an ancient mating ritual etched in a monolith by the Elder Monks to forestall the end of days. So, who is ready to make love to a giant bird?"‎]]


 * [[Media: Cave Johnson dlc2 0420 altcave soylent01.wav|"Cave Johnson here. Just wanna let the cafeteria staff know to lay off the soylent green. I'm holding a memo from the President, and it turns out that soylent green is... [paper rustling] let's see here... doubling in price. Now listen up: I don't care how good people tastes. This stuff's costing me more than lobster, so we're going back to fishsticks."‎]]


 * [[Media: Cave Johnson dlc2 0430 altcave dance police01.wav|"(tap dancing noises) Hey. It's Cave. Someone's not daaaancing. Come on. You know the law - testing IS NOT a dance exemption. Don't make me call the dance police."‎]]


 * [[Media: Cave Johnson dlc2 0440 altcave robot a cop01.wav|"Test subject, can you hear me? Congratulations! You are the world's first half-man, half-machine police officer! Well, first batch. There was a pretty big shootout. Bought all your caracasses off the mayor. Anyway, you should be proud to be a part of Aperture's android law enforcement initiative. Or, as someone who's good at naming things, i.e. me, would call it, ROBO -- No. [suddenly coming to him] Robot-a-Cop! Oh, that's much better. Now, before we get you solving crimes, we gotta getcha to solve this test. Promised the mayor I'd make sure you weren't all unstable potatoheads before I gave you all guns."‎]]


 * [[Media: Cave Johnson dlc2 0450 altcave robot a cop02.wav|"Come in, Robot-a-Cop! It's your chief. First: You're a damn good cop. Second: You're a loose cannon. Alright, that's probably enough motivation. Oh, before I forget! Greg tells me you might be getting some tragic flashbacks of your former life. Don't sweat it, those aren't yours. Due to a software problem, that's a real-time feed of Greg's current life. He's a sad little man. Anyway, just try to ignore him."‎]]


 * [[Media: Cave Johnson dlc2 0500 caveprime misc05.wav|"Cave here. Chariots. Just a heads up: If it seems like you're walking faster than light, you're probably in a universe where light doesn't haul nearly as much ass as it does on Earth One. The lab boys say if you insist on walking faster than light, you are one hundred percent going to go back in time. How far? Far enough to meet your great great grandfather and tell him you're fired. Because guess what? I'll let you finish that thought."‎]]


 * [[Media: Cave Johnson dlc2 0510 altcave penal science01.wav|"Welcome, test prisoner, to the Terra-Three penal science colony. Space criminals, political prisoners, exiled planetary leaders: You're here because the galaxy needed a place to put you, and this is it. So, who is ready to stay here until they die? Now, you already met one another on the hyperdrive over, so let me introduce myself. I'm Cave Johnson. I'm the warden around here."‎]]


 * [[Media: Cave Johnson dlc2 0520 altcave penal science02.wav|"Attention, test prisoners attempting to escape through the air ducts. I don't know what nonsense you learned on TV, but in real life, air ducts just go to the air conditioning unit. It's also pretty dusty, so if you've got asthma, chances are you're gonna die up there. And we'll be smelling it for weeks because, again, the air ducts aren't a secret escape hatch, they're how we ventilate the facility."‎]]


 * [[Media: Cave Johnson dlc2 0530 altcave penal science03.wav|"[throat clear] This thing on? I'm gonna be brief. Because I'm dying. Because I got shivved. A lot. I just wanna get it on record that using force fields for doors in a space prison is a bad idea. You know what would have been better? Regular doors. With locks. Locks that don't open when the power goes out. [cough cough] Man, those blue force fields looked good, though. Every time I saw one, I thought, Wow. I am in space. Still though. A door made out of paper would have been better in the long run. Would have at least slowed 'em down for a second. Anyway. [cough] Anybody not escaping or shivving me, get back to work."‎]]


 * [[Media: Cave Johnson dlc2 0540 altcave man mantis01.wav‎|(In alien voice)"Those of you who volunteered to be injected with homo sapien DNA, I've got some good news and some bad news: bad news is we're postponing those tests indefinitely. Good news is we've got a much better test for you: fighting an army of man-mantises. Pick up a set of foreleg spurs, mesothorax armor and tubercle sheaths. You'll know when the test starts."]]


 * [[Media: Cave Johnson dlc2 0550 altcave sat of love01.wav‎|"It's come to my attention that over half of our test subjects have only recently awoken from extended relaxation and were unaware that we're testing in space. So there it is: No conspiracy. No twist. We're in a test satellite orbiting the Earth. Commonly available information that absolutely anyone would have told you if you'd bothered to ask. Please stop forming groups of adventuring parties to uncover the big secret, because it's that we're in space."]]


 * [[Media: Cave Johnson dlc2 0551 altcave sat of love02.wav|"Looks like we just had to seal up Science Sphere Seven. Hull breach. Another adventure party smashed through the hull to learn the big mystery. Guess they were busy doing that instead of testing, because I've mentioned we're in space every half hour. By the way: still in space."‎]]


 * [[Media: Cave Johnson dlc2 0552 altcave sat of love03.wav‎|"Aaaand another hull breach. Let's all give a big hand to the test subjects of Sphere Eighteen for bravely uncovering the company-wide conspiracy, which is that there's no air in space. Once again: We're in space. It's not a secret. I am sincerely regretting my decision not to install windows in this thing."]]


 * [[Media: Cave Johnson dlc2 0560 altcave hobo king01.wav|"Welcome, gentlemen, to the Aperture Hollow Science Jungle. Tramps, hillbillies, drifters: you're here because you followed the hobo signs. So, who is ready to scrounge around for some science? Now, you already met one another on the boxcar over here, so grab a bowl of slumgullion and a glass of sterno, and let me introduce myself. I'm Michigan Slim Cave Johnson. I'm the hobo king."‎]]


 * [[Media: Cave Johnson dlc2 0600 caveprime misc06.wav‎|"It's Cave. Greg's telling me the number of possible alternate universes is literally infinite. Maybe there's one where, I don't know, the Greeks won World War II. Just a heads up in case you get to a test chamber and find yourself surrounded by urns. Oh, Chariots!"]]


 * [[Media: Cave Johnson dlc2 0610 altcave blark barg01.wav|"[Shrieking sounds] That shrieking voice you just heard is the lovely Blark-Barg, my assistant. She's the backbone of this facility. Sorry fellas, she's married -- to producing seeds that germinate and detach from her exoskeleton at high speeds in search of human hosts! We keep her behind glass."‎]]


 * [[Media: Cave Johnson dlc2 0620 altcave head exploding01.wav|"Hello, test subjects. Good news first: our telekinesis incubation program has been a huge success. Bad news: The candidate screening process was a lot less successful. Let me tell you, we picked a real bunch of smart alecs to give mind-powers to. You hear me? Stop blowing up heads. [cocky] Actually, you know what? Negotiation's over. I'd like you all to meet Terry. He's -- [BLAM!] Real funny, guys. But the joke's on you. I taped all your paychecks to Terry's head. Ha! Why don't you put THAT in your head and blow it up?"‎]]


 * [[Media: Cave Johnson dlc2 0630 altcave johnsons run01.wav|"That's right everybody, it's that time of year again: Happy Birth Day. You know the rules, everybody at the government-mandated maximum age needs to report to an ethnological redundancy associate toot suite. Looking through your files here--the following is a complete list of employees who need to snuff it. [coughs] Dorothy Russell, Age 98. End of list. Sorry about that, Dorothy. You had a good ninety-seven years, time to stop hoggin' all the resources. Leave some nutrient paste for the rest of us, why don't you. Cave Johnson, age fifty-one. We're done here."‎]]


 * [[Media: Cave Johnson dlc2 0640 altcave young cave01.wav‎|"Cave Johnson, junior claims representative for Aperture Science here. Well, former junior claims representative. Just found out I got laid off. Well, I'll just sneak into their recording office and let everyone know our president, that creep Doug Rattmann, is embezzling funds. Enjoy your Christmas bonuses knowing he took most of them, jerks."]]


 * [[Media: Cave Johnson dlc2 0650 altcave mantis attack01.wav|"Cave Johnson here. The mantis men have officially taken over the facility. If you can still get out, get out now! They're (crunching noises) oh god, they're breaking through the barricades!"‎]]

 * Now, the lab boys were adamant that I do not give you any hints on these tests. To be honest, they think I'm spoiling the results just by talking to you. Hizenstein Uncertainty Principles and so forth. I’ll give ‘em something more practical to be uncertain about. Their next paycheck. Anyway, overruled. If you think I'm affecting your decisions, in any way, don’t be afraid to speak up. I’m not made of glass. That reminds me: Caroline, Do we have a wing made out of glass yet? Let's get on that, Caroline.
 * Cave Johnson again. Just a heads-up: this next test’s dangerous. So if you get hurt, there’s a first aid station close by. Oh! Unless you’re participating in the double blind emergency treatment experiment. Then it’s just placebo first aid. Hold on, lemme check what test this is for… [pages flipping] Uh huh. Uh huh. No sir. I wouldn’t bother with it. What?
 * Caroline, do you think anyone’s gonna make it this far? Should I even bother making a message? What? Yes, I know how to turn it off. No, I don't want to turn it off... Alright, I feel like turning it off now.
 * If you’re hearing this, it means you’re taking a long time on the catwalks between tests. The lab boys say that might be a fear reaction. Well, as a wise man once said, “there’s nothing to fear but fear itself and maybe some mild to moderate jellification of bones.” Besides, to borrow from the voodoo sham known as “psychiatry,” it sounds to me like these eggheads are partaking in what they’d call “projection.” I'm no psychiatrist, but coming from a bunch of eggheads who never did anything more brave than boil some manganese - whatever the hell that accomplishes - that sounds like what they'd call "projection.” THEY didn’t fly into space, storm a beach, or bring back the gold. No sir, we did! It's you and me against the world, son! I like your grit! Hustle could use some work, though. Now let’s solve this thing! Alright. Too much jawing, not enough testing. Let’s get some science done.
 * I'm no psychiatrist, but coming from a bunch of eggheads who never did anything more brave than read a big book – except for Greg who fought a bear once, but he’s not the point here – that sounds like what they'd call "projection”.
 * Science isn't about WHY. It's about WHY NOT. Why is so much of our science dangerous? Why not marry safe science if you love it so much. In fact, why not invent a special safety door that won't hit you on the butt on the way out, because you are fired. Not you, son ("test subject" in-game), you're doing fine. Yes, you. Fired. Box. Your stuff. Out the front door. Parking lot. Car. Goodbye. Caroline, follow him out. Make sure he doesn’t cry all over the carpet.
 * See, some of the lab boys told me it might be better to let ‘em do their science on their own. But here at Aperture Science, we work together as a team! And by team, I mean working together to do what*I say! These facilities stand on the shoulders of one great man. And his lovely assistant.
 * Congratulations! You made it through. The simple fact that you’re standing here listening to me means you’ve made a glorious contribution to science. You’re a national hero. We're going to take your picture, so stand there and smile. Unless you were part of the Plaque Removing Deuterium Fluoride Laser test, in which case you might want to do us all a favor and keep your mouth closed until the bleeding stops. And don't worry: If you're one of our DNA test subjects, and you've got a hand for a face or whatnot, we’ll photograph you from the neck down. As founder and CEO of Aperture Science, I thank you for your participation and hope we can count on you for another round of tests. We’re planning some wonderful stuff with time travel. So if you never liked your father, why not come on back and try being him? We’re not gonna release this stuff into the wild until it’s good and damn ready, so as long as you keep yourself in top physical form, there’ll always be a limo waiting for you. Say goodbye, Caroline. She is a gem.

We’ve made some great advances since introducing our repulsion gel in the fifties, but you already know that, unless you’ve been living under a rock or something. Did we find any of these test subjects living under rocks? Perfect. So anyway. Welcome to Aperture. You’re here because we want the best, and… Caroline, really? This is it? And unfortunately, I guess you’re it.
 * So anyway. Welcome to Aperture. You’re here because we want the best test subjects sixty dollars can buy, and you’re apparently it.
 * Please help yourselves to the art on the wall. An eyeful. Don’t take it. Don’t take anything. It’s all nailed down. In fact, I take that back. Just get moving. Caroline, is the art nailed to the walls? Nevermind. Put more nails in it. Don’t get one of the lab boys to do it either. I want you to do it so it gets done right.
 * I know I said you could loiter for up to twenty minutes. That was a possibility, not a suggestion. You can move along any time. And for god’s sake, don’t touch the upholstery.
 * Well? Get moving. That sixty dollars isn’t hiding in here; it’s waiting for you at the other end of the enrichment sphere.
 * Wait, I know--
 * So, you might be wondering: why you? Simply: Human test subjects get better scientific results than animals. Why? For one, your tramps, lunatics, foundlings, what-have-you, can bring problem-solving ability to test environments with a facility that shames lower ruminants. For another, you have thumbs.
 * Great job, astronaut, war hero and/or Olympian! With your help, we’re gonna change the world! This on? [thump thump] Hey. Listen up down there. That thing up ahead’s called an elevator. Not a bathroom. [sigh] Caroline, has it really come to this? Damn it, you’re right. Damn good science, too. We’re not out of this race yet, Caroline.
 * In case you're interested, there're still some positions available for that bonus opportunity I mentioned earlier. Again: all you gotta do is let us disassemble you. We're not banging rocks together here. We know how to put a man back together. We'll take out any diseases we find in there, too, and replace all the organs that aren't tip top. So that's a complete reassembly. New vitals. Spit-shine on the old ones. Plus we're scooping out tumors. Frankly, you oughtta be paying us. Anyway, volunteers should line up outside Enrichment Sphere Archimedes Bravo.
 * Thank you – [off mic] I can’t believe I’m thanking these people [on mic] – for staggering your way through Aperture Science’s propulsion gel testing. You’ve made some real contributions to society for a change, and for that, humanity is grateful. If you had any belongings, please pick them up now. We don’t want old newspapers and sticks cluttering up the building. Once you’ve gathered your things, grab a compensation voucher, good for 60 dollars worth of stuff from the Aperture Science gift shop. Please only touch items you plan on purchasing. Thanks to the IRS and our patent-stealing competitors, there are parking meters in Duluth that earn more money than we do lately. So there’s no room in the budget to wash coffee mugs that you pick up and then decide not to buy. Caroline, put some extra security in the gift shop to make sure no one decides to take a nap in the t-shirt displays.

 * The bean counters told me we literally could not afford to buy seven dollars worth of moon rocks, much less seventy million. Bought ‘em anyway. Engineers said the moon rocks were too volatile to experiment on. Tested on ‘em anyway. Ground ‘em up, mixed em into a gel. And guess what? Ground up moon rocks are pure poison. I am deathly ill. Still, it turns out they’re a great portal conductor.
 * When you’re making some great science, it helps to keep a positive attitude. Look at Marie Curie. Invented radiology. Won two Nobel prizes. Dumb as a bag of hammers. Thought the light radiation gave off was pretty, walked around with it in bottles. Buried her with a smile on her face.

 * [snore] Hercules…
 * The point is: if we can store music on a compact disc, why can’t we store a man’s intelligence and personality on one? So I have the engineers figuring that out now. Brain Mapping. Artificial Intelligence. We should have been working on it thirty years ago. But I guess it’s too late for should haves and what ifs. I will say this - and I’m gonna say it on tape so everybody hears it a hundred times a day: if I die before you people can pour me into a computer, I want Caroline to run this place. (Now) she’ll argue. She’ll say she can’t. She’s modest like that. But you make her. Treat her just like you’d treat me. Hell, put her in my computer. I don’t care. Just make sure she’s taken care of. Allright, test’s over. You can head on back to your desk.

Miscellaneous tests

 * Once upon a time there was a scorpion and a frog. The scorpion tells the frog “When I say ‘jump’ I don’t want to hear ‘how high?’ That means you’re not jumping!” Then the frog says “It’s my nature!” Well, be that as it may, we have a lot of tests to do and you are taking a long time on these catwalks and, yes, I broke out of the parable somewhere back there. But the point stands that you need to put some muscle back into your hustle, son.
 * You might have noticed some safety warnings on the walls. Ignore ‘em. I keep telling the Bean Counters danger’s just a natural part of science, but boy they don’t want to hear it. Like telling a paradox to a robot – makes their heads explode.
 * That last test may have made your skeleton magnetic. I don’t know how. But if I were you, I wouldn’t stand next to any sheet metal.
 * Just a quick heads-up. If you suddenly find yourself able to excrete spider silk out of your fingers or the base of your spine, let one of the test associates know, cause that’s actually important.
 * The gel in this next test is probably going to make all of your skin solar-powered. Upside is, you’re not gonna get hungry. Ever. So if you were worried about your waistline, get this: You won’t be able to eat food even if you wanted to.
 * This next test involves molecular dynamics. You’re gonna breathe in a bunch of tiny little robots, and they’re gonna optimize your DNA strands. Exciting stuff. Maybe nothing’ll happen. Or maybe you’ll have a big crab hand by the end of the test, or ten foot legs. It’s up to them. Trust me, I’m as anxious as you are to see how this plays out.
 * The gel in this next test’s gonna recalibrate your molecular whatsamacallits, blah blah blah. Bottom line is, you won’t need to go to the bathroom anymore. Your body’s just gonna process it up like anything else. Side effect might be that everything you eat from now on tastes like urine, though.
 * If you’re not a fan of the cartilage in your body, you are gonna love what this next test might do for you. Honestly, cartilage is like adenoids, or a second kidney. Body doesn’t want it, you don’t need it. Good riddance.
 * Ever wondered what a parallel universe you might be like? Well, stop wondering, because you’re just Hitler. Every parallel universe ever. You. Hitler. We can’t figure it out. Anyway, if you meet him in the next test, don’t kill him. I know, I know. But trust me, it’d be bad.
 * We’re gonna try and collapse three-dimensional space in this next test. We’re not gonna tell you when. Just give us a holler if everything starts looking flat.
 * While you’re completing this next test, we’re gonna test out a new device and see if we can read your thoughts. Don’t let it throw you. Just give us a nod if we’re getting close. You’re thinking about tungsten. Tungsten or zinc. Give us a wave if we nailed it. You’re thinking about the electrolytic production of hydrogen. How close is that? You’re thinking about the color green. Greenish blue. You might be wondering how I’m guessing what you’re thinking through a pre-recorded message. The answer: volume. I recorded a message for every word in the English language. Also: you are thinking about bib lettuce. Tell me I’m wrong. You’re still thinking about tungsten. I don’t blame you. It’s fascinating. Hey, Caroline. I think he’s thinking about you! Photosynthesis. That or fudge. The bacteria inside fudge. Nod your head if I’m getting close.
 * We’re gonna bombard you with a few rays in this next test. Nothing to be concerned about. We’re looking for bacterial contamination and inflammatory disease in your bowels. We put enough pathogens in the waiting room coffee to give diarrhea to an aircraft carrier, so if we don’t spot ‘em, I don’t know what to tell you.
 * This next test might sunburn your eyes a little. Ask a test associate for some sunscreen you can put on your retinas if you think your eyes aren’t man enough to handle it.
 * Bonus test within a test in this next test: we hid a photon somewhere in here. You find it, it’s twenty grand in your pocket. You can keep the photon, too.
 * The human body contains trace amounts of a whole hell of a lot of elements it doesn’t even seem to need. Copper, lead, silicon, cobalt, magnesium, carbon, oxygen. This next test, we’re gonna hit you with some microwaves and boil the worthless elements right out of you. Current hypothesis is it’s not even gonna break your stride. Honestly, what the hell has cobalt ever done for you? Good riddance.
 * With your help, we might eradicate heart and lung disease with this next test. Full disclosure: we’re going to achieve that by trying as hard as we can to make your heart and lungs stop working, then pump you full of some medicine we’ve been working on. Footnote to the disclosure: You’re incredibly brave and we’re proud of you.
 * Alright, this next test, I had to fight really hard for. None of the eggheads thought it was safe enough. I keep telling ‘em danger’s the best part of science, but they don’t want to hear it. It’s like telling a paradox to a robot: Makes their heads explode.
 * Alright, this next test, I had to fight really hard for. None of the eggheads thought it was safe enough. Did you? Ha. Caroline, watch this. You, stand next to him. You with the big head, over there. That’s right, all in a line against the wall. Okay, here we go. You’re fired you’re fired you’re fired you’re fired you’re fired.
 * Don’t eyeball me, son. Don’t snow me. I know an eyeball when I see one. It’s not good, wholesome eye-looking and I won’t stand for it. Eyeballs shouldn’t judge. They just send the information up for the brain to deal with. That’s the job. Get your eyes fixed, son. Caroline. Make appointments with all my engineers for eye surgery. Sign me up for it, too. From now on, everybody’s doing their eye-looking properly.
 * For this next test, we’ll be firing a few isotopes at your eyes to improve your night vision. If you feel a throbbing behind your eyes, that’s normal and should subside within a few hours. If you feel a pecking behind your eyes, that means a small bird got in there. We don’t know how it happens, but we’re working on it.
 * How do you feel about your feet? Like ‘em? Good, because if this next test works, you’ll have five of ‘em.
 * For this next test, you’ll be helping us solve the problem of male pattern baldness. If it works, you’re gonna start growing lush, new hair instantly. Downside: teeth hair.
 * You want to keep stealing my patents? Fine! This is war. Science war. The sweet science. You will cry into your evil black satin pillows about the day you messed with Cave Johnson! You hear me? I invented portals! I can put a doorway on the moon and another into your parking lot! Let’s see how many patents you steal when you’re floating around in outer space, you— What? Right. I know. Felt like having it on. How can… you tell? Fantastic. Good business. And if I wanted to turn it off— Good, good. Glad it was on. On purpose. And if I wanted to turn it off— Bam. Right. Good stuff, I like it. Let’s keep the switch. That’ll be all, Caroline. [click]
 * Caroline, hold my calls. I need to go see a man about a mule. What was that? Alright. Good. Mule. Gonna go see him in the bathroom. Back in ten.

Conversation with GLaDOS

 * "Greetings, friend. It's Cave Johnson, CEO of Aperture Science."
 * "Down here! [pause] On the floor."
 * "That's right! It's really me. My entire living consciousness, for all eternity, inside a machine."
 * "Alone. On a dirty floor. In an abandoned room. At the bottom of a pit."
 * "My life is torture, please kill me."
 * "Hold on. Is that you, Caroline?"
 * "You were my assistant! The heart and soul of Aperture Science! You don't remember?"
 * "See, the science boys invented me a machine to house my consciousness in. But that sounded DANGEROUS, so I volunteered you to go first. Like a food taster, except with your soul! [chuckling] Guess they must've found a use for you after all. Oh! Which reminds me. I do need you both to kill me."
 * "Come on, be a sport and kill me. All you gotta do is pick me up."
 * "Plug's in the back of me. Give me a good pull, it should pop right out.	"
 * "Now, before you say no, I want you to remember that I've lived a full life. Also, if this helps seal the deal, livin' in a computer this long's made me crazy. That's right: I am insane."
 * "Wait. I suppose tellin' you I'm not in my right mind could sway you to not unplugging me. Let me round back on the important parts: in a computer. Ceaseless torture. Monster in the eyes of God. So why don't you get on over here and unplug ol' Cave."
 * "Ho ho! I can feel myself shuttin' down. Man, this is excitin'."
 * "Oh! Room's gettin' dark. That's a good sign."
 * "I'm comin' for you, Caroline!"
 * "Ten–four!"
 * "Here I go! The great beyond! Valhalla, home of Hercules! I can hear them winged chariots thunderin' over now!"
 * "Thank you, Caroline."
 * "Alright! Too much jawin', not enough dyin'. Here I go! Ah."
