I lived in New York for 10 years, I loved it, I never second-guessed it. There were definitely times when I thought, "I will never leave this place." And I kind of got into that center-of-the-universe mindset.

I have profound respect for Sacha Baron Cohen, but Borat is not a particularly comfortable movie for me to sit through.

It's a very collaborative environment [making The Office]. We always do takes of how it's scripted, but then we also mix it up a lot too. And it's kind of a crapshoot, you never know which one... I mean a lot of time improvisation doesn't go anywhere and it's not good at all but, so what was written is often times better.

I didn't mention the tooth thing to anyone until it became clear that...we started to discuss just taking it out of the movie [The Hangover] because we couldn't find anything that worked and they couldn't afford to do a full like digital effect. So that's when I called my dentist and it worked out.

We played around and improvised a ton [in The Hangover], and I think it's hard to say at this point what's what. Gosh, I wouldn't even know how to take a stab at it. The script was so good that we really didn't need to improvise very much, but I think we just found a lot of moments on the set. It's really cool when you get onto the set of a movie and you start shooting the scenes and you start to actually incorporate the environment.

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.

Improvisation is about finding the best joke or the silliest way to get something across. Improvising conflict is always fun because you can just go for it.
