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.

It's the business of movies, it's the fights that go along with the level of budget, and more than anything, it's the creative constipation of having to live with one idea for two or three years. It's just not that fun.

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

I love to musicalize things. You do employ a whole level of gravity. You use the emotional heft of music.

That decision to commit your life to certain principles and a certain narrative, if I wrote a paper on that, I know I'd find inconsistencies.

There are good characters and bad characters.

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.
