Honestly, it's really hard improvising and it's really stressful and humiliating at times. You're taking really big swings that potentially are eating up a lot of people's time and resources at set in your attempt to discover something funny.

There was a year straight where every weekend, I went to at least one bar mitzvah or bat mitzvah, and we would all go, and it was a lot of fun. We sneak some beer; we'd hang out; we would try to get with girls and not. And usually we'd just end up hanging out together alone.

I guess it's a kind of a goal for any actor to be the lead of a movie. Not for ego reasons, but because it is creatively the biggest challenge.

We [with Judd Apatow] started talking about ideas and he said, 'Well, I'm going to do this movie Knocked Up with Seth [Rogen], but after that you guys should do a movie together.' I read it and thought that it was very funny.

I actually live right near a high school and I always walk by...I live in a high school. I actually live in the boiler room of a high school at night. When I see high school guys now I'm actually like, 'Thank f - king God I'm not in high school anymore because they look like they could kick the living s - t out of me.'

After every single take, I laugh. It's my own awkwardness and discomfort about being an actor.

I'm the person who writes most of my movies so every role is exactly what I want to be doing.
