I've always thought that comedy was just another dramatic expression. I try to measure the amount of truth in a work rather than just looking at the generic distinction between comedy and drama. There's a lot of bullshit drama that leaves you totally cold. And there's a lot of wasted comedy time too. But when you get something honest, it doesn't matter what label you give it.

The comic impulse is sometimes a reaction to sadness. You feel like you can make one choice or the other.

I can't imagine a successful comedy movie without a successful comedy performance at the heart of it.

With both Caddyshack and Vacation, it's not like the subjects were serious enough that they engaged my interest for another round. I love the characters, and the actors were great, but I didn't see the need to make another Vacation movie.

I believe things happen that can't be explained, but so many people seem intent on explaining them. Everyone has an answer for them. Either aliens or things from the spirit world.

If people work together, if they can keep a cooperative spirit and use their ingenuity and balance it all with good humor and good will, then there's nothing to be afraid of. That's the sappy part of it, ... On the other hand, every Halloween for many years when my kids were trick-or-treating I would put on my 'Ghostbusters' jumpsuit with a police flashlight to protect all the kids from ghosts.

I think satire is a luxury of literate middle-class people. People who are well fed and relatively secure in their beds can laugh at their troubles. They can enjoy sitcoms. For those who aren't quite so lucky, well, the irony might be lost on them.
