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.
