There are currently more political parties in Iraq than unbombed buildings to hold them.

People who grew up in New York City or Los Angeles tend not to even understand what goes on in the rest of the country. I'm really glad to have grown up in an environment where I actually was kind of a weirdo because I was obsessed with comedy and movies and stuff.

I'm sort of laughing and so Zach [ Galifianakis] started laughing [on the set of The Hangover]. And Todd [Phillips] was baffled because what we were saying wasn't that funny, you know what I mean? And it was like all the baby's face. So Todd was like, 'What is going on? Get it together guys.'

We spent six weeks there [in Vegas]. The only thing crazy that I did was shoot that movie [The Hangovers]. The stuff in that movie is way crazier than anything I might have done, drunk one night in Vegas. I mean we did it for real in the movie, so that's as crazy as it got.

Getting any movie made is just like trying to push a giant boulder up a mountain, and there's so many moving parts. Obviously, there's the creative side, and then there's the logistical side, and they're both colossal.

That's actually a rare thing to be on a set full of people that you admire and make you laugh all the time.

I'm working on a script right about Civil War re-enactors who go back in time to the actual Civil War. It's kind of a big, crazy Back to the Future comedy. So, of course, it's the Civil War - I play the banjo. I was just having a conversation with one of the producers about some of the material and he was like, 'You know, we have to work in a scene where you play the banjo. And I was like I'll get behind that.
