"Late Night with David Letterman" is without a doubt the most clever, experimental (apologies to Steve Allen and Ernie Kovacs), and downright hysterical television program in TV history. To describe it would be pointless, because so many different things would happen in a given show. From about 1986 to about 1990 was Dave's finest period (he was still smiley sarcastic Dave and hadn't yet become angry sarcastic Dave), but the show was very solid overall. The Top Ten lists on those shows were 50 times better than the lists on the CBS show, and to me are some of the most valuable comic documents of this century, a sort of numerological Dave Barry.
Kids, you think Tom Green was the first person to get into confrontations on camera? Check Dave when he went to bring "those weasels at G.E." a fruit basket and was promptly escorted out. Sure Viewer Mail and Stupid Pet Tricks were Dave's trademarks (both superior to the CBS versions), but it was things like the "Late Night Thrill Cam" and "Network Time Killers" and the show filmed in an airport, and the show that was played at a high speed to "save time," etc. that made Late Night the best thing on TV when it was on.
