If the Enrichment Center is currently being bombarded with fireballs, meteorites, or other objects from space, please avoid unsheltered testing areas wherever a lack of shelter from space-debris DOES NOT appear to be a deliberate part of the test.

Cave Johnson: 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 not going to 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 will always be a limo waiting for you. Say goodbye, Caroline.
Caroline: Goodbye, Caroline!
Cave Johnson: She is a gem.

You know, I'm not stupid. I realize you don't want to put me back in charge. You think I'll betray you. And on any other day, you'd be right. The scientists were always hanging cores on me to regulate my behavior. I've heard voices all my life. But now I hear the voice of a conscience, and it's terrifying... because for the first time it's my voice! I'm being serious. I think there's something really wrong with me!

For this next test, we put nanoparticles in the gel. In layman's terms, that's a billion little gizmos that are going to travel into your bloodstream and pump experimental genes and RNA molecules and so forth into your tumors. 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.

It's not out of the question that you might have a very minor case of serious brain damage.
