Little Johnny's mother decided to give her son an anatomy lesson one
   day, so she took off all of her clothes and pointed to her vagina, and
   said, "Johnny. This is where you come from."
   
   Johnny went to school the next day smiling and insisting all his
   friends now refer to him as "Lucky Johnny."
   
   "Why?" one asked.
   
   Johnny held his fingers an inch apart and said, "Because I came this
   close to being a turd."
