While visiting a friend who works at a local hospital, I learned more than I wanted to about the sick sense of humor shared by people in the medical profession. While eating lunch in the hospital cafeteria I overheard two nurses discussing a patient who had recently gone through a lung transplant. "Well, how is Mr. Jones?" "He's doing as well as can be expected for a guy who's coughing up somebody else's phlegm."
