I was a fan after seeing one of his first shows, in which he had his dentist on as a guest to critique Reds, the Warren Beatty movie about the Russian revolution, all from the point of view of dentistry. The guy was deadpan serious, using still images to point out historical fallacy in dental work, anachronism and such. It came across as the real thoughts of a real dentist, in the sort of conversation one might have during an office visit. Dave's affection for the guy was obvious - and you can see that in this interview with Grace Hopper, too. He shows genuine interest in her, and enjoys her qualities as a person, so he lets her talk. So many talk show hosts obstruct and interrupt and make themselves the center of attention. Dave was different from the start and it was refreshing.
