Not any more. Hayes quit South Park, solely because of its take on Scientology. First of all: Lighten the fuck up. Scientologists take their pseudo-religion way too seriously considering it's based on a science fiction author's ramblings about ghosts from space. Second of all: South Park has made fun of anything and everything for almost 10 years now, and he chooses this one thing to quit over?
Matt Stone (co-creator of the show) said it best:
"He has no problem — and he's cashed plenty of checks — with our show making fun of Christians.....He wants a different standard for religions other than his own, and to me, that is where intolerance and bigotry begin."
Yup. I'd say he's one of the smartest guys working in the entertainment industry.
P.S. This creepy bronze bust is supposed to be Isaac Hayes.
