You take a vacation to a place like Thailand and you're ready for the excitement of something new and foreign. But when you're working 14-hour days, all you want is something familiar to ground you. And there's just nothing there.

It's incredibly fun to play someone that you don't like. It exorcises your own demons in a way. It's cathartic. We all have things that we don't like about ourselves, little things. And I get to amplify those things and put them out there. It's fun and it has a cleansing effect.

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.

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.

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.

We did some camera tests blacking it out, we made a prosthetic with a gap in it, but that made me look like a donkey, so I vetoed that right away. And then I just finally called my dentist and said, 'You know, I've had this implant for 20 years. What's it involve in taking it out?' And he said, 'It's actually not that big a deal. We can do that.' So we took it out and I was toothless for three months, for the run of the movie [ The Hangover] .I take my job very seriously.

I'm kind of embarrassed by how quickly I adjusted to L.A. I really love it. It's so pleasant.
