I bet doctors have humor all their own.  Dentists, Anesthesiologists, Surgeons, Veterinarians, General Practitioners, Cardiologists.  Especially Electro-Physiologists.  I bet their conventions are raucous with wild hilarity and very few actual human body parts sneaked in for some of the more elaborate humor.

Not that you or I would get ALL the jokes.  Orthopedists, for instance, think that “humorous” is funnier spelled “humerus”, and that one gets past me, somehow.  It just doesn’t tickle my funny bone.
