If you remember you don't remember Jack Parr, then you must surely remember him. (sounds like a "Rummy-ism)
I liked Jack Par best of all those characters.
Ahhh, I must admit I'm a Rummy fan! I don't remember watching The Tonight Show when Jack Parr was the host, but, I do know (remember) that he was Carson's predecessor. (whew, I think I got out of that one :-))
