Brevity is the soul of wit.

Humor is kindly. Wit is caustic.

Never argue with a fool, onlookers may not be able to tell the difference.

I was young and foolish then; now I am old and foolisher.

I've never fooled anyone. I've let people fool themselves. They didn't bother to find out who and what I was. Instead they would invent a character for me. I wouldn't argue with them. They were obviously loving somebody I wasn't.

I am a fool, but I know I'm a fool and that makes me smarter than you.
