From the Parents Television Council, August 22, 2001:
Some people here think South Park is great simply because it is politically incorrect and takes shots at liberal sacred cows like Barbra Streisand and Janet Reno. It's a shame it takes sickos like the creators of South Park to get that done.
The July 11 episode [of South Park] began with Cartman, the most clueless of the fourth-graders, informing his pals that he now had pubic hair. He reassures them that “this doesn’t mean we can’t still hang out. It just means that I matured faster than you.”It seems that Cartman, unaware that a person grows pubic hair when he or she’s old enough, bought the hair in question from Scott, an unscrupulous ninth grader, for ten dollars. Once he realizes he’s been taken, Cartman is furious (“I’m gonna get that son of a bitch!…That a—hole!”) and plots his revenge. He tries to train a pony to bite Scott’s penis off, but the pony won’t cooperate, instead fellating the fake penis Cartman provides.
That, incredibly, brought to a close the more tasteful portion of the episode.
Cartman then devises a scheme which results in Scott’s parents trespassing on land owned by a “crazy redneck.” The landowner fatally shoots the parents. Cartman takes their bodies, saws them up, and makes them one of the ingredients in a chili which Scott eats at a cookoff. (The dismemberment isn’t shown, but once Cartman tells Scott what he’s done, Scott reaches into the chili and pulls out one of his mother’s fingers, her engagement ring still on it.)
