One of the biggest breaks we had actually, one of the biggest, the hardest I laughed on the movie [The Hangover] was the baby was just doing ridiculous things and making hilarious faces. But I'm sitting there and I'm supposed to be having this exchange with Zach [ Galifianakis] and the baby is like staring at me with these huge eyes and acting, and just making the most cerebral faces, and I could not keep it together.

[Chickens] are very frenetic. So if you think about it and you look back in other movies, like if someone's taking a crazy bus ride somewhere and it's like, 'Oh, what makes this bus ride crazy?' There's a chicken in the aisle, or like there's a chicken in a crate. So I just think the presence of chickens makes things crazy.

God bless him, I mean a lot of times you get non-actors on a set and they get really self-conscious, especially when doing something crazy like singing along with Phil Collins. They get sort of reserved and self-conscious. Mike [Tyson] completely trusted Todd [Phillips] and totally put everything into it.

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.

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

Working on The Daily Show, I co-produced all those field segments, and that's another huge thing.I probably did more than 100 field segments.
