As an editor, you're constantly dealing with the best way to convey an exchange between two people. So when I'm shooting, I'm just aware in the back of my head what an editor might want.

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.

My friend and I sang an a cappella rendition of Extreme's "More Than Words" at one of our football pep rallies in a desperate attempt to look cool. For a while, I wore pink Converse All Stars because I thought it made me seem daring and irreverent.

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.

You are literally too stupid to insult.

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.
