I've always been into toys and kits and models. I'm kind of a toy nerd.

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

I'm the worst in The Office. It's a problem. They've had to shut down the set for like 30 minutes because of me.

It's a fascinating culture [the South in the Civil War period] and so rife with comedic possibilities. And not in a way that...I have no intention of making fun of re-enactors. I think it's more just a celebration of their passion and enthusiasm, which is so infectious and maybe at times a little misguided.

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.

[Mike Tyson] was fantastic. Well, here's the cool thing about Tyson. It turns out he's a huge fan of Old School, which was one of Todd Phillips' earlier movies. So he got to the set and he already liked Todd and he trusted Todd.

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.
