Sean Penn's really the only one stupid enough to put anything down on paper.

When someone goes, 'Oh, this group is really pissed off at what you said,' there's not a piece of my body that goes, 'Sweet!' That means I did it wrong. I'm just trying to make people laugh.

Living is having ups and downs and sharing them with friends.

Before the church responded, a lot of people would ask us, 'Are you afraid of what the church would say?' And Trey and I were like, 'They're going to be cool.' And they were like, 'No, they're not. There are going to be protests.' And we were like, 'Nope, they're going to be cool.' We weren't that surprised by the church's response. We had faith in them.

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.

All the religions are super funny to me.

It's this simple law, which every writer knows, of taking two opposites and putting them in a room together. I love anything with Cartman and Butters at the same time, it's great.
