Alcohol causes conflicts, firearms resolve conflicts.

I'm pretty sure no one's reading action scripts saying, 'This has got to be Ed Helms.'

The improv stuff, that's always surprising so a lot of times that's really funny.

We spent six weeks there [in Vegas]. The only thing crazy that I did was shoot that movie [The Hangovers]. The stuff in that movie is way crazier than anything I might have done, drunk one night in Vegas. I mean we did it for real in the movie, so that's as crazy as it got.

I mean the fun part about when Andy Bernard sings on The Office is he usually embellishes the songs in fun, stupid ways. That's just something that I do in life, like in the shower or whatever. So a lot of that stuff is pretty spontaneous.

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.

What's cool is that in the story of the movie [The Hangover] our characters are also really kind of getting to know each other and bonding over the course of the movie. And I think you're seeing a real, a literal sort of friendship growing both in us as actors and on screen as characters.
