Sometimes you just create a joke out of thin air in the editing room. I'm really glad I've had that experience. It gives me a little more confidence in front of the camera.

The improv stuff, that's always surprising so a lot of times that's really funny.

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.

So long as your desire to explore is greater than your desire to not screw up, you're on the right track.

I was just fooling around with the piano and Todd [Phillips] was like, 'Hey there's a great spot in the movie [The Hangover] where we need a little bit of a breath in the narrative. You should write a song and stick it in there.' And I was like, 'Well, what should the song be about?' And he said, 'The tiger.' 'Oh, okay.' So I went off and I wrote this song. I came back and Todd and I tinkered with it a little more and then we shot it right then. It all happened in a day.

[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.
