Cinderella wanted to go to the ball so she sought out her Fairy Godmother for advice. "I will let you go to the ball, Cinderella," she said, "but you must do two things. You must wear a diaphragm and you must return before 2:00 a.m. or else your diaphragm will turn into a pumpkin."
Well Cinderella went to the ball but it was already past 2:00 a.m. and she wasn't home yet. Then it was 3:00 a.m....then 4:00 a.m....and finally Cinderella arrived safely home. Her Fairy Godmother looked at her and said, "I see you have finally made it home. How was the ball?"
"Just fine," replied Cinderella. "Everything went fine."
"Well how can that be?" replied the Fairy Godmother.
"I met this nice Prince and we had a wonderful time."
"You knew what would happen to your diaphragm if you didn't return by 2:00 a.m. and this is always a sure thing. So tell me about the Prince. What was his name?"
"I'm not sure but it was something like, Peter, Peter, Pumpkin......."
