A brilliant, quick witted comic whose heyday was the late 1950's and early 60's. Had his career side tracked with some mental problems. I always loved seeing him on the Steve Allen Show in the early 1960's. He even did a stint on Mork and Mindy as their son. Probably at the request of Robin Williams who is a big fan. See "It's a Mad, Mad, Mad World for some of his best film work. He was one of the key characters in a movie that had at least 50 well known comedians in it.

A genius. Even after fifty years, he is as quick-witted and hilarious as ever- for proof, just buy the "Outpatients" CD he released a few years ago. Any comedian who knows the business of making people laugh must bow down before the king of improvisation. His mind works so quickly that it amazes me- he can come up with things off the top of his head that most writers would kill to come up with.

I used to sneak to a tv to watch him because I knew that he would make me fall down.time went on, no more sneaking, I fell down for decades. he was incredible.I loved that he would break up any host who had him on a show

Greatest improvisational ever!

Very funny and was WAY ahead of his time in the late 60s/early 70s.
