I find both Leno and Letterman rather pathetic. Jay Leno has this thing he does at the beginning of the show where he bounds out and shakes hands (or just touches) members of the audience. I find it rather revolting.

I agree that neither Leno or Letterman are that funny. Leno's habit of repeating the punch line of a joke is irritating. Actually, towards the end of his run, I found Johnny Carson's monologues incredibly boring but at least he was a decent interviewer.

And that brings me to another point. I seem to remember that Carson's monologue was about ten to fifteen minutes followed by several guests. Leno, on the other hand, uses half the show's time for his monologue and skits and spends far less time with guests. Occasionally I listen to Leno or Letterman when there's a guest on I want to see. Inevitable I'm dissapointed.
