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

Do goofy stories make people nice? What if, in their goofiness, these stories somehow inspire that in the right way. Is that a social good?

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.

We're kind of like the smoking section in high school. We're immature, keep to ourselves.

It is like football with coaches, like, 'We're only going to think about the next game.' It is really true, all you think is, 'Okay, we have to make a good next episode.'

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

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.
