I realised that all one really had to do was just observe. Observe and slightly exaggerate, and you had comedy. Instead of creating a mythical premise for a stupid joke, I found playing off truth got the best result.

When I was a little boy, I thought when I grew up I would talk Yiddish. I thought little kids talked English, but when they became adults, they would talk Yiddish like the adults did. There would be no reason to talk English anymore, because we would have made it.

Comedy is serious - deadly serious. Never, never try to be funny! The actors must be serious. Only the situation must be absurd. Funny is in the writing, not in the performing. If the situation isn't absurd, no amount of joke will help.

When I was a little kid at home, I thought the whole world was Jewish. For years I thought Roosevelt was Jewish. I loved him. I thought of him as my father. I'm always stunned when I find out that people like Roosevelt and Tolstoy weren't Jewish. How could I love them so much?

Rhetoric does not get you anywhere, because Hitler and Mussolini are just as good at rhetoric. But if you can bring these people down with comedy, they stand no chance.

Cat angels are the reason there are no mice angels.

Well, you know, 'Spaceballs' is a weird combination, because it's a simple, sweet little fairytale, and it's crazy and out-there and making fun of and taking apart sci-fi, 'Star Wars', and 'Star Trek'.
