19. Theodoric of Yorick, Medieval Barber
Original Airdate: April 22, 1978
Steve Martin is one of SNL's all-time greatest hosts not merely for the record-holding frequency with which he's appeared (second only to Alec Baldwin), but for how he was the rare host that brought his own comedic sensibility to bear on the show's format. Theodoric of York, Medieval Barber was typical SNL in its period satire and silly costumes, but there was something very Martin about the shrewdly embedded commentary on the smug superiority every era feels about the previous era's scientific practices and customs. "Just 50 years ago, we would've thought that your daughter's illness was brought on by demonic possession or witchcraft. But nowadays we know that Isabelle is suffering from an imbalance of bodily humors, perhaps caused by a toad or a small dwarf living in her stomach."
