What's cool is that in the story of the movie [The Hangover] our characters are also really kind of getting to know each other and bonding over the course of the movie. And I think you're seeing a real, a literal sort of friendship growing both in us as actors and on screen as characters.

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'm sure I cause just as much consternation for editors as any other actor, but it definitely makes me feel more comfortable understanding how and why all the different camera setups exist.

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.

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.

A lot of kind of like the way that Andy [Bernard] talks, you know, the writers pick up on those things - little moments that I inject and then they start to write it in later. It's hard to say if a whole storyline is spun out of an improv. I feel like it has happened on The Office, I just can't think of it.

The biggest thing that comes out of improv that gets built on is just character traits. You know, for me the singing was born out of improv.
