My favourite minor recurring character was the literal doctor...
Dr. Fishman: "It looks like he's dead."
Michael: "Just to be clear. Looks like he’s dead, or he is dead?"
Dr. Fishman: "It just looks like he’s dead. He’s got like blue paint on him or something. But he’s going to be fine."
Also, I believe this was taken at one of those Tea Party rallies last year...
