For many centuries man has called his genitalia by the name shlong or talliwhacker. For those men who have yet smaller ones, they call them wee wees. A wee wee is a gross looking penis with a face on the head scribbled in blue ink.
Little Georgey asked him mom for a new toy, so she told him to go play with his wee wee if he had nothing to play with. He played with his wee wee and soon the house blew up.
