“South Park” takes on “Scientology”

“Have you seen this, have you heard about this?”

On Wednesday’s ninth-season debut, Hayes’ character, Chef, pops up in an episode which creators Trey Parker and Matt Stone are devoting to his mysterious return to “South Park.” They are expected to poke fun at his religion, Scientology.

While details are scarce, Comedy Central officials say the duo are putting the finishing touches on the episode (Wednesday, 10 p.m.) — which, like many others, is being written and animated in less than a week.
