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.

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

Sometimes we come up with something great, but a lot of times it just feels like work.
