Life is too serious to do farce comedy.

I've simply been brought up being knocked down.

I'm so sorry I fell down.

The camera can't catch my blushes!

It was an event when you could get all three of them on the set at the same time. The minute you started a picture with the Marx brothers you hired three assistant directors. One for each Marx brother. You had two of 'em while you went to look for the third one and the first two would disappear.

Tragedy is a close-up; comedy, a long shot.
