This one comes from “Overheard in New York”(see here) which I think means it’s something that someone actually heard:
Apple’s Next Anti-PC Marketing Campaign Takes Shape
Office thug #1: Yo, Windows is, like, mad-retarded!
Office thug #2: Say what?
Office thug #1: I said Windows is bullshit, man.
Office thug #2: Man, I been telling you that shit for years. My G5 is way better than whatever computer you got.
Office thug #1: Nigga, my laptop has AIDS!
