Cave Johnson here. Ever hate hiring people to do work? Not here at Aperture, we got robots replacing all of our jobs. Actually, now we need mechanics to fix the robots. Eh, just replace the mechanics with robot mechanics, then fire the guys that thought of the 'replacing people with robots' thing. Introducing the pants supplier of the future, a cotton gin. This baby separates things faster than a blac-what do you mean I can't say that joke? Anyways, it works on things, cotton, grenade pins, test subject limbs which, trust me, took a lot of time to clean up. Robot janitors, that's what we need next. Cave Johnson, we're done here.
