You're never nice to your friends. You're nice to people you don't like!

I'm not worried about young people seeing an opportunity and taking advantage of it.

My dog's a gentleman.

How many days do you have that are just purely dramatic? How many days do you have that are just purely comedic? It's usually a combination and I think that's what real life feels like.

Directors tend to be more underrated than overrated because it's a quiet job and people don't really understand it.

I make decisions to do movies based on the cast. I'd just been working with Zach Galifianakis on 'The Hangover', and I was thinking, I've got to find something to do with this guy immediately.

I think that 'Hangover II' is as funny as 'The Hangover I,' honest to God, but I think that it's a little bit darker, and the stakes are a little bit higher.
