When I've written for Bill Murray - I've written six films for him - people would read it and say, "Oh, that's so perfectly Bill." He'd read it and say, "Are you kidding? I can't say these words." So it's all about perception.

I've never taken a script to the stage or to principal photography and said, "This is perfect. This is as good as it can possibly be." It's not Shakespeare, you know; you know it can probably be better.

It's a great luxury for me to be able to write on the films that I direct, and kind of a nice thing to be able to write enough to get credit, which is difficult for a director.

Stand-up is every man for himself; you learn from hanging out at these clubs and watching other guys, and then trying not to be like them.

First and foremost, you have to make the movie for yourself. And that's not to say, to hell with everyone else, but what else have you got to go on but your own taste and judgment?

I'm not a believer in the pratfall. I don't think it's funny just to have someone fall down.

You don't have to know much, just a little bit more than everybody else.
