South Park started as a little video Christmas card.

Sometimes I go into my own little world. It's okay, they know me there.

I spend a lot of time thinking about what I do and how it fits into the scheme of things. I won't do something just because it's funny.

So the actual riffing came out of us just sitting there and doing it the way I think some people think we really did it, which is all spontaneously, and it really was.

If you notice any of the press from when I was with the show, I would always deny it being the year 3000.

Eventually I got asked to be in a Michael J. Fox sitcom called High School U.S.A. I didn’t think it was funny and said no. They doubled the money, and that kind of offended me. I realized, oh, that’s right, my opinion means nothing in Hollywood. I’d seen other people compromise, and I felt that once you gave up on what you wanted to do, you couldn’t go back. It was selling out. So I decided to go back to Minneapolis.
