An otherwise older gentleman had an appointment to see the urologist; the waiting room, sharing offices with several other doctors, was filled with patients. Approaching the receptionist's desk and giving his name, he found the receptionist a large unfriendly woman who looked like a Sumo wrestler.

In a very loud voice, she broadcast, "Yes, I have your name on the list; you want to see the doctor about impotence, right?"

All the patients in the waiting room snapped their heads around to look at the very embarrassed man. He recovered quickly, however, and in an equally loud voice responded, “No, I'm here to inquire about a sex change operation  -- but I don’t want the same doctor that you had.”
