One day the teacher walked to the back of the room where Little Johnny was sitting and found him with his hand down his pants. She asked, "Johnny, what are you doing?" Little Johnny said, "It hurts down there." "Well then," said the teacher, "You need to go to the nurse and see if you can go home."
A little while later, Johnny came back to the classroom and took his seat. When the teacher walked over she was shocked to see Little Johnny had his dick hanging out of his pants. The teacher said, "Johnny, what's that doing hanging out of your pants?!"
Little Johnny said, "The nurse called home, and my mommy said if I can stick it out till noon, she'll come and pick me up."
