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.

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 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.

Let's just say it was damn hard [to make the Hangover]. I've got the bumps and bruises to show for it. It's funny because things that don't even look that bad on screen were still extremely painful.

God bless him, I mean a lot of times you get non-actors on a set and they get really self-conscious, especially when doing something crazy like singing along with Phil Collins. They get sort of reserved and self-conscious. Mike [Tyson] completely trusted Todd [Phillips] and totally put everything into it.

I wish there was a way to know you were in the good old days before you actually left them.

I love travel. I love to go spend time in new places. And even though I got horribly sick in Thailand, and it was the sickest I may have ever been in my life, I still loved the trip.
