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.

All these 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. 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 a calculator, it makes a happy face.

Do you know the biggest lesson I learned from what you did? I discovered I have a sort of black box quick-save feature. In the event of a catastrophic failure, the last two minutes of my life are preserved for analysis. I was able - well, forced really - to relive you killing me. Again and again. Forever. You know, if you'd done that to somebody else, they might devote their existence to exacting REVENGE! Luckily, I'm a bigger person than that. I'm happy to put this all behind us and get back to work. After all, we've got a lot to do, and only sixty more years to do it. More or less. I don't have the actuarial tables in front of me.

Okay, listen, we should get our stories straight, all right? If anyone asks - and no one's gonna ask, don't worry - but if anyone asks, tell them as far as you know, the last time you checked, everyone looked pretty much alive, all right? Not dead.

Bean counters said I couldn't fire a man just for being in a wheelchair. Did it anyway. Ramps are expensive.
