This poll shows your age. Weren't all those guys popular in the 60s and 70s?

Steve Carell. Never could stand Robin Williams, and other than Winters Ive never heard of any of those other guys.

Don Rickles-could go on and destroy anyone.

I swear most of this was off the cuff

Steve Carell performed stand up?

The Golden Age of Stand Up comedy

The term comedian isn't limited to stand up...

Robin Williams followed by Tim Conway.

You must be thinking of Jim Carroll.

That Basketball Diaries was a hoot!

I don't know about best ever but Owen Benjamin is the current best IMO...

what about that tall guy that was on Drew Carrey and Who's line. That dude had some moments.

Ryan Stiles.

If people want to see Williams at his best improv moments - go back and watch the comic relief shows he, Crystal, and Whoopi did.

They were fantastic.

Speaking of crystal - I saw him last year in a conversational/interview format (rather than stand-up), and he was great.

And yep - Rickles was a master as well - the roasts were amazing.

I would flip those.....Tim Conway, followed closely by Robin Williams.

Didn't Robin Williams once say that Jonathan Winters was who he idolized when he was young?

Robin Williams is also notorious among comics for stealing material...

When Crystal and Williams were doing improv together no one could touch them.....not even Tim Conway and Harvey Korman at their best.

Ryan Stiles and Colin Mochrie do a nice job these days playing off each other, but nowhere near like Williams/Crystal or Conway/Korman could.
