Isaac Hayes was an unfunny singer and voice actor who was most famous for being the voice of the token black character "Chef" in South Park and then became much, much less famous when it was revealed that he had left the show because of his firm belief in Scientology. Many are still of the belief that he may have actually left because Chocolate Salty Balls became far more popular than his much famed score for Shaft.
On August 10th, 2008, Isaac Hayes died from a stroke. By dying, Chef managed to avoid a more humiliating death at the hands of a white cop or from going broke by donating all of his money to fight an impending Thetan invasion. Some fans think that, despite Isaac Hayes's loyalty, the Co$ had him killed when they finally realized that he was not the kind of person they wanted as a celebrity spokesman. What a fucking sucker.
