Sometimes you just create a joke out of thin air in the editing room. I'm really glad I've had that experience. It gives me a little more confidence in front of the camera.

I'm sort of laughing and so Zach [ Galifianakis] started laughing [on the set of The Hangover]. And Todd [Phillips] was baffled because what we were saying wasn't that funny, you know what I mean? And it was like all the baby's face. So Todd was like, 'What is going on? Get it together guys.'

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.

Getting any movie made is just like trying to push a giant boulder up a mountain, and there's so many moving parts. Obviously, there's the creative side, and then there's the logistical side, and they're both colossal.

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

Almost everything is in the movie [The Hangover]. I think the fun little Easter eggs on the DVD will be sort of the gag reel stuff. There's a lot of takes we just couldn't get through.We were laughing.

There is something beautiful in the mundane if you take enough microscope to it and focus in on something that seems innocuous to begin with.
