Little Billy'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,
saying, "Billy, this is where you came from."
Billy went to school the next day smiling, insisting that all his
friends refer to him as "Lucky Billy."
"Why?" one asked.
Billy held his fingers an inch apart and said,
"Because I came this close to being a turd."
