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 piano song that I do in the movie [The Hangover], it's a great example, that was never - that wasn't in the script.

When we were not shooting [The Hangover] we were sleeping, so pretty much every waking moment we spent together. And, you know, Bradley [Cooper], Zach [Galifianakis] and I were acquaintances before the movie started but we became good friends very quickly and spent so much time together that it was just inevitable we were either going to really hate each other or really like each other. Thank god it turned out to be the latter.

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 happen to think singing is hilarious, especially when it pops out at the wrong time.

I'm glad to always have that connection to a part of the country that doesn't really have anything to do with what I do. That said, there seems to be a lot of production drumming up in Atlanta these days. It would be kind of a dream come true to go back to Atlanta to work on a movie, but we'll see what happens.

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