The scene [in The Hangover] where the tiger actually pops up behind us, that's actually a Jim Henson tiger puppet. The Jim Henson Company actually supplied that tiger. And it's really cool. Its entire face moves. It has like all these little motors in its eyebrows and cheeks and mouth. It was amazing.

I mean the fun part about when Andy Bernard sings on The Office is he usually embellishes the songs in fun, stupid ways. That's just something that I do in life, like in the shower or whatever. So a lot of that stuff is pretty spontaneous.

My friend and I sang an a cappella rendition of Extreme's "More Than Words" at one of our football pep rallies in a desperate attempt to look cool. For a while, I wore pink Converse All Stars because I thought it made me seem daring and irreverent.

Shouldn't EVERY week be Infection Control Week?

Almost everything is in the movie [The Hangover]. I think the fun little Easter eggs on the DVD will be sort of the gag reel stuff. There's a lot of takes we just couldn't get through.We were laughing.

It's just one of those things like when you're not supposed to laugh, it makes it that much harder to stop laughing. And for some reason Zach [ Galifianakis] and I get in this feedback mood of giggling, and on the set of Hangover we just couldn't get through stuff.

[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.
