I am watching this episode because it's his final one.
Over the years he has been on late night, I probably only seen a dozen of his episodes and that was only because he had a particular guest that I like on like the actors who played James Bond or an actress or supermodel or female singer I liked.
I still have that episode with Madonna on VHS where Madonna was embarrassing him and she wouldn't let him cut to commercial and she took up most of the episode and wouldn't let him bring on his other guests for that night.
