Well, maybe Einstein or Jonathan Winters. The comedian, who died Friday at the age of 87, was immediately hailed by Steve Martin, Robin Williams and others as a genius.

He made hit comedy albums, was a regular on the old Tonight Show, memorably knocked down a gas station in It's a Mad, Mad, Mad, Mad, World and co-starred with and inspired Robin Williams.

But Winters was best known for creating a repertory company of characters that he carried around in his head. He told us how he built that cast after some advice from another performer at a club in New York:

"You know, we did Cagney and we did Karloff and John Wayne — Duke Wayne, you know, and these guys. And an old man said to me, 'You know, your routines that you're doing, these impressions are great, Jonathan, but can you accept a little criticism?' I said, 'Sure. You've been here longer than I have, Jack. Let's hear it.'
