Well, for me, it's the relationship between comedy and life - that's the edge I live on, and maybe it's my protection against looking at the tragedy of it all. It's seeing life in balance. Comedy and tragedy co-exist. You can't have one without the other. I'm of the school that anything can be funny, if seen from a comedic point of view.

Nothing reinforces a professional relationship more than enjoying success with someone.

I never work just to work. It's some combination of laziness and self-respect.

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.

We are all several different people. There are different aspects of our nature that are competing.

How one handles success or failure is determined by their early childhood.

Life has all of these contradictory feelings and contradictory results. People spend their whole lives struggling to get what they think they want, and even if they get it, they find that it's either not what they wanted, or it comes with so many unwanted consequences. We're always shut off from pure joy.
