This word gets overused in describing actors but I think it applies to Mike [Tyson] in this case - he was totally fearless. He jumped in and played with us comedically and improvised a lot. A lot of jokes in those scenes with him are from him improvising.

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.

I found myself often asking the question, "Who deserves to be made fun of?" Depending on your mood, the answer can be no one or everyone. It took me a while to understand the math of how those field pieces came together. I don't think that ridicule is ever funny, but there are times when that gets the biggest response.

Chickens are a symbol of chaos. Wherever you stick a chicken, unless it's a chicken farm, it's just chaos.

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.

It's incredibly fun to play someone that you don't like. It exorcises your own demons in a way. It's cathartic. We all have things that we don't like about ourselves, little things. And I get to amplify those things and put them out there. It's fun and it has a cleansing effect.

As much as you do get beat-up doing even small action sequences, it's incredibly fun.
