I think Johnny Carson was the best late night entertainer they have had. I dont remember him when I was growing up cuz he was on too late but I have seen some old reruns of him when he was younger and he was so silly and got himself into some funny stuff. He quieted down when he was older but I still liked him better than Jay Leno who I dont find funny at all. I enjoyed Letterman's monologues and when he does that segment "Great Moments in Presidental Speaches" and made fun of Bush. That was some funny stuff right there. But none of them are good now I find. If there was a good one I would tape it and watch at another time. I dont find the appeal for Conan O'Brien at all.
