In a very loud voice, the receptionist said, "YES, I HAVE YOU'R 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 am equally loud voice replied, "NO, I'VE COME TO ENQUIRE ABOUT A SEX CHANGE OPERATION, BUT I DON'T WANT THE SAME DOCTOR THAT DID YOURS".
The room erupted in applause!
There is a lesson to be learned here - Don't mess with old folk!
