[echoey] Hello, test subject. Echo. Echo. Welcome to your first test. I'm your overseer, Cave Johnson, and I think, if you keep testing, you might find something very interesting about this planet. [chuckle] [beat] It's me. I'm the planet. You live on me. Wanted to save it till later, but man -- it's just too darn good. You really wouldn't have seen it coming. Do me a favor, don't tell any of the other test subjects. Also, don't pollute.
