I thought the use of sterotypes and bad music made it even funnier, but that's just my opinion. I still remember when his song "Amish Paradise" was big...it's still one of my favorites. Anyone who has made fun of Michael Jackson's songs has a few points in my book. Thanks for the link, palefrost.
You have to wonder what kind of drugs he's taking to come up with some of this stuff. Either that, or he just has WAAAY too much time on his hands. He is funny, though. He probably just says the things everyone else thinks and is afraid to say.
