Oh, you know what one can say about themselves? I am a murderous artificial intelligence who enjoys testing test subjects... whenever I feel like it, really, which is basically all the time. If you're lucky enough to find yourself in my clutches.. err, Rather I mean, "volunteering" at Aperture Laboratories, you'll be handed cake. And, oh yes, cyanide too. Or maybe cyanide inside the cake... Honestly, I forget now. What were we talking about again? Oh, right me. Fabulous, isn't it?
