Now, you've got to understand that I have no real interest in South Park -- it's just not my thing. But there's been a bit of a fuss going on since Isaac Hayes announced that he was quitting the show, because of the way that it made fun of religion. I understand that Hayes' character, Chef, once punched out Jesus in a boxing match on the show, which apparently was not a problem for him. Making fun of Scientology, however, was beyond the pale.
Rumor has it that Tom Cruise pressured Comedy Central's parent, Viacom, to pull the scheduled rerun of the Scientology episode, which the network did. The response from the creators of South Park is here.
