An older gentleman had an appointment to see the urologist who shared offices with several other doctors.
The waiting room was filled with patients. As he approached the receptionist's desk, he noticed that the receptionist was a large unfriendly woman who looked like a Sumo wrestler. He gave her his name. In a very loud voice, the receptionist said,
"YES, I HAVE YOUR NAME HERE; 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, and in an equally loud voice replied,
"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!
