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?"

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.

Those of you who volunteered to be injected with praying mantis 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 mantis men. Pick up a rifle and follow the yellow line. You'll know when the test starts.
