Recently, there was a public television special honoring writer Larry Gelbart, whose credits include the TV show M*A*S*H*, the movies Tootsie and Oh, God, and the Broadway revival of A Funny Thing Happened On The Way To The Forum.

At one point, Carl Reiner was seated between Gelbart and Mel Brooks, talking about the days when they all worked for Sid Ceasar.

One great moment went something like this:

Carl Reiner: (pointing at Larry Gelbart) Im sitting between the wittiest and (pointing at Mel Brooks) funniest people that I know.

(With perfect timing, Mel Brooks does a spit-take and sprays a mouthful of water at the audience.)

Host: Can you tell us what the difference is between witty and funny?

Larry Gelbart: (without missing a beat) Witty is dry.
