I was thinking of Theodoric, Barber of York from the old SNL's. Those were some sick skits.
The Julia Childs skit where they had her cutting off all her fingers.
Does anybody else remember the SNL parody automobile commercial where the rabbi performed a bris in the backseat of a car? It was a parody of the Ford diamond-cutting commercial to illustrate the smooth ride. The front tire hits a pothole just as the rabbi is making the delicate cut. It was pretty amusing.
