I distinctly remember a "Tonight Show", it HAD to be with Leno due to my living situation at the time, with both Robin Williams and Harry Connick Jr. I expected Williams to be his normal crazed self, but Connick kept up with him every step, pratfall, and joke of the way. It HAD to be Leno, because I rarely watched Letterman, and I remember Jay putting his feet up on the desk and letting them go at it the rest of the show.
I remember them jumping across seats in the audience, running all around the studio, absolutely hilarious. Probably second funniest thing I saw there, after Buddy Hackett's Duck joke. (see You Tube for that one!)
Am I nuts? Was it Letterman? Did it really happen? I can't find any listing that shows those two on either Letterman or Leno or Carson together. But I KNOW they were. Connick had a movie out, or soon to be out, but I can't correlate his films with anything either.
Am I nuts?
