Perhaps The Great Man Isn't To Blame

Isaac Hayes did not quit "South Park." My sources say that someone quit it for him.

I can tell you that Hayes is in no position to have quit anything. Contrary to news reports, the great writer, singer and musician suffered a stroke on Jan. 17. At the time it was said that he was hospitalized and suffering from exhaustion.

It’s also absolutely ridiculous to think that Hayes, who loved playing Chef on "South Park," would suddenly turn against the show because they were poking fun at Scientology.
