Because of Mozart, it's all over after the age of seven.

Sometimes I want to clean up my desk and go out and say, respect me, I'm a respectable grown-up, and other times I just want to jump into a paper bag and shake and bake myself to death.

Being a grownup means assuming responsibility for yourself, for your children, and - here's the big curve - for your parents.

So when you tell a joke, you want to make someone laugh, or if you tell a story about someone who had a heart attack, it may be because you want the listener to exercise. Stories are tools to create social cohesion and to get humans to strategize together.

I'm not a comedy guy. I don't do comedy shows.

I started being a comedy fan when I was, I'm going to guess, like 5 or 6 years old.

As a director, you can't stop a guy if he thinks something's hysterical, because if you do, then he'll get depressed because he thinks he didn't come up with a good joke. So if a guy's going on some run and it's killing him, and he thinks it's hilarious, you gotta do enough so that he thinks you can use it in the movie.
