GLaDOS: Congratulations, you managed to break both yourself and Aperture Laboratories Product's Warranty all at once, certainly you look happier with a third party manufacturer's repair service, and that's good because i can't fix you up again, you know, because you broke your warranty. now i'm a good person and i still care for your safety, as a part of our big family of Aperture Laboratories' products i'm concerned about your proper performance, that's why i decided to conduct some… tests on you, nothing big, just the usual simple tasks, it'll be fun i promise

Wheatly will find a way to break it; don't worry about it.
