Actually I find that the "South Park kids'" swearing is about 50% of what's funny about the show. Amazingly, it has NEVER gotten old to me. Hearing Cartman yell out *SOB* in that inimitable voice with the angst in it makes me *LOL* every time...

Or when he was selling aborted fetuses...."You're breaking my balls..."

Cartman has the best comic timing of anyone on tv now with the possible exception of Kevin Dillon on Entourage.

You keep using that word...I do not think it means what you think it means...

as evidenced by the 50 or so people in my office who do a pretty good Eric Cartman...

I think the swearing is funny only because it fits.
When Cartman says SOB, anybody else in that situation would say the exact same thing.

There is a big heart in South Park because of the respect they have for their characters. For example, Token, Timmy and Jimmy, in other tv shows would be charaters who would teach everybody an important lesson. On South Park they are real kids.
