People have a lot of different beliefs, and at the end of the day, we all have deeply held beliefs that probably don't make sense to anyone else.

To me, every episode is like a song, and every season is like an album. There's that part of the day when you first get the idea and you say, "This could be really funny." And you sit down and you write it. There's just something that happens there that doesn't happen when you really give it a lot of time beforehand.

In terms of the creative side of it, it's really been a thing where you come up with the funny stuff is usually at a bar or out talking to people or whatever.

We're the guys who, if someone says you really shouldn't do an episode making fun of Scientologists, we say, 'Whatever.' Someone says, 'They might come try to burn your house down,' we say, 'We'll just get another one.'

Bargaining makes you come up with the best ideas.

No, writing musicals is the hardest thing in the world. And it was really funny, because I remember when the South Park movie came out, there were some critics that said, 'Well it's obvious that in order to get it to be 90 minutes they filled some time with music.'

Sometimes what's right isn't as important as what's profitable.
