When I was in NYU Film School I drove a taxi in New York for two years, I felt like I owned my own business with that little taxi.

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.

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.

There's such an awkwardness to most heterosexual male relationships. You see women who are friends, and they kiss each other good-bye, and they're just so much warmer with each other. But there's this thing with guys where, even between best friends, there's a standoffishness.

You're only as good as your body of work, and everybody has issues, whether it's Steven Spielberg or Martin Scorsese. I'm not comparing myself to those guys, but you learn more from the misses than the hits.

I never had a ton of male friends and it's always been something that's really interesting to me, what brings guys together? The bonding. 'Old School' is a good example of that. And even 'Starsky' and even 'Road Trip.'

Comedy is so subjective. You could be in a room with 400 people laughing at a joke and you could just not think it's funny. You're just sitting there like, 'Am I in the twilight zone? Why is everyone laughing?' It's such a personal thing. People have such a personal visceral response to comedy.
