Little Johnny's parents got divorced. One night Little Johnny walked past his mother's bedroom, the door was open, and he sees his mother lying on her back playing with herself, saying "I need a man... I need a man..."
A few nights later he walks past her bedroom again, the door's open, and he sees his mother with a man on top of her.
Little Johnny runs to his room, jumps on his bed, pulls down his pants and starts playing with himself, saying, "I need a bike... I need a bike... "
The angry wife met her husband at the door. There was alcohol on his breath and lipstick on his collar. "I assume," she snarled, "that there is a very good reason for you to come waltzing in here at five o'clock in the morning?"
