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.

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.

The Daily Show was an incredible training ground for that kind of thing. It was all about discipline and generating material constantly.

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.

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.

It was never tough [ being the new guy]. It's just the warmest group of people [The Office stuff] you could ever hope to work with.

To be totally candid, it was really born out of a panic attack the summer between my sophomore and junior years, when I realized I wasn't going to graduate in four years unless I somehow managed to glue together all the courses I'd taken. That said, I'm really glad I did it, 'cause it was really fun, and I was able to just take whatever the hell I wanted.
