Cinderella was getting ready to go to the ball when she realized that she started her period and had no tampon.  Her evil step-sisters would not give her one before they left for the ball.  She started crying and her fairy godmother asked:  "What's wrong Cinderella?"  She replied:  "I started my period and have no tampon."  
The godmother said:  "I'll give you a tampon but on one condition.  You must be home at twelve because at midnight, the
tampon will turn into a pumpkin".  "No problem" said Cinderella and left for the ball.  The godmother was waiting for her to return - 12:00, 1:00, 2:00, 3:00, - Cinderalla comes waltzing in at 4:00 in the morning.  The godmother said:  "What happened to you?  I was worried sick about you".  
Cinderella's answer was:  "I was on my way home at midnight when I met a man named Peter Peter something".
