A guy had an appointment to see a urologist who shared a receptionist with a group of other medical doctors. He made his way through the waiting room full of patients and as he approached the receptionist's desk, he noticed that the receptionist was a large woman with a fixed scowl on her face who looked like a Sumo wrestler.

He gave her his name and mentioned his doctor's name and appointment time.

She replied, gruffly and in a VERY loud voice, "YES, I SEE YOUR APPOINTMENT HERE. YOU WANT TO SEE THE DOCTOR ABOUT IMPOTENCE, RIGHT?"

Virtually all of the patients in the waiting room snapped their heads around to look at this exchange.

Terribly embarrassed, the man recovered quickly, and in an equally loud voice replied, "NO, NO. I'VE COME TO INQUIRE ABOUT A SEX CHANGE OPERATION, BUT I DON'T WANT THE SAME DOCTOR THAT DID YOURS."

The room erupted in applause.
