I do not watch ANY late night talk show any more. I watched Carson up to a point. I watched Letterman. Never got into Leno or Rivers or Colbert or O'Brien.
I guess Jimmy Kimmel is the only one who sort of makes me laugh. But none of them make me laugh like Steve Allen did. His man on the street interviews, his soap operas that panned to faces in the audience, his introductions designed to deflate egos....his piano ad libs.....
