I spend shockingly little time thinking about real-world stuff.

Me and Matt love to argue, but in general our sense of humor is pretty much alike.

When you're superhot, you don't have the time to enjoy being superhot, because you're working your ass off. By the time we will actually have time to really go out and screw around, we won't be hot anymore.

My fear is that, as soon as I get married and have kids that I'll kind of do what a lot of people do and suddenly start making, 'Now I'm gonna make films for kids.' I really hope I don't do that.

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.

It's all based on saying the shocking thing. We used to have a great time going to Hollywood parties and saying 'I think George Bush is doing a great job.' We'd clear out the room. I used to love it.

It's not like we have a formula, but I think one of the reasons this show has survived is that it has a big heart at its center. Other cartoon shows have people crap on each other and make racist jokes. But I don't think people tune in for that. I just don't think a show lasts for 10 years without a heart.
