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!
DON'T MESS WITH US OLD FOLKS!
Thanks sis & Grant! This is an old one but still just as funny now!
