Well done. Here are the test results: You are a horrible person. I'm serious, that's what it says: "A horrible person." We weren't even testing for that. Don't let that horrible-person thing discourage you. It's just a data point. If it makes you feel any better, science has now validated your birth mother's decision to abandon you on a doorstep.

Cave Johnson: 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-...

Caroline: Sir, the testing?

Cave Johnson: Right. Now, you might be asking yourself, "Cave, just how difficult are these tests? What was in that phonebook of a contract I signed? Am I in danger?" Let me answer those questions with a question. Who wants to make sixty dollars? Cash. You can also feel free to relax for up to twenty 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. So! Welcome to Aperture. You're here because we want the best, and you're it. Nope. Couldn't keep a straight face.

The square root of rope is string.

Did you feel that? That idiot doesn't know what he's doing up there. This whole place is going to explode in a few hours if somebody doesn't disconnect him. I can't move, and unless you're planning to saw your own head off and wedge it into my old body, you're going to need me to replace him. We're at an impasse.

Crushing's too good for him. First he'll spend a year in the incinerator. Year two: Cryogenic refrigeration wing. Then TEN years in the chamber I built where all the robots scream at you. THEN I'll kill him.
