There's something uniquely aggravating about the smugness of liberal Hollywood.

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.

In our show, there's usually a comeuppance. Or, if not, it's an anti-ending. And you're supposed to get that.

I hate conservatives, but I really hate liberals.

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

Once you get yourselves into things that are working on a deeper level, you just have to keep going. When you reach that deeper level, you can't go back.

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