I don't think there's really observational magic.

Every day I live by only one rule, be a good guy.

It was always the most fun thing in the world to think of a joke area and talk about it with someone like Jim Carrey, and then he would get on stage fearlessly and tear the house down. That's something I always enjoyed. It also allowed me to not be terrified.

I've come to believe that the simpler the title, the better. Whenever I try to get cute with it, it seems to be a problem but if it's just The 40-Year-Old Virgin, people seem to know what they're in for.

I remember the Time review [on the Hit and Run]said that there wasn't one laugh in it. And I had watched the movie 50 times with audiences, and it always played great. There was certainly a moment where you could tell the audience was like, "Wow, this is really getting weird."

A lot of times, it's easy to trim the movie 'cause you just start losing things that you thought would be there just for amusement's sake that actually are not funny. My favorite part of the process is seeing it with an audience. I do about eight previews to see how things are working.

All my cuts are always about three hours, at the start, mainly because any scene in the movie that's 90 seconds, I probably shot a five-minute version of. If you just extrapolate that through the whole movie, I have a very long version of every scene, usually because, if there's one funny joke, I'll shoot five because I don't know if the one I like is going to work. I'll get back-ups because my biggest fear is to be in previews, testing the movie, and a joke doesn't work, but I have no way to fix it because I have no other line.
