My film about Bush didn't prevent his reelection.

North Korea has taught a great lesson to all the countries in the world, especially the rogue countries of dictatorships or whatever: if you don't want to be invaded by America, get some nuclear weapons.

I've been encouraging documentary filmmakers to use more and more humor, and they're loath to do that because they think if it's a documentary it has to be deadly serious - it has to be like medicine that you're supposed to take.

I really didn't realize the librarians were, you know, such a dangerous group. They are subversive. You think they're just sitting there at the desk, all quiet and everything.

The libraries are just like the ass end of everything, right?
