I used to have a friend who was probably a diagnosable psycho but was undeniably a funny guy. He once wrote a pretty funny cartoon about hating his neighborhood full of yuppie scumbags. He was a drunk, too, and one night he went out with a pack full of plain white stickers and went around covering up their Erase Hate and Al Gore bumper stickers with slightly different messages. I recall one went Dig Up
Polly Klass So I Can Fuck Her In The Ass. And "I (swastika) Jews". Then he went home and passed out.
Imagine his surprise when he woke up and watched the local news the next evening. Lots of vandalism to yuppie cars, and at least one physical assault. I don't know where he is now, but I'd like to think that wherever he is he's doing something to piss off rich lefties.
