We've rewritten entire scenes and had them animated twelve hours before the show goes on the air. It's not fun.

We've had musical stuff in the show [South Park] forever. That's mostly because Trey's a big musical fan, and he's a great songwriter. He's been writing songs his whole life. So since the beginning, we've always put a lot of musical moments.

If you're working with a band and you really want to work them into the episode, you've got to say to them, "Look, we need you around every day and on Tuesday night all night because we need you to do voices as we're changing stuff." We do the show so quickly, and you just can't get bands to do that. It's not really fair.

I've been to China and Russia, and I don't know anything about Chinese or Soviet relations.

I just get my news from the Internet.

Even celebrities, most people have a sense of humor. Most of the people we meet who we've done on the show, like it.

The last few years on ‘South Park’ we have done some of the riskiest things we have ever done, knowing it could kill the show, but we also know that’s what we have to do.
