A five-year-old kid raised his hand at school. The teacher declined to let
him leave the room. Five minutes later she reversed herself. She said, "All
right, Sonny, you may go now."
The little boy looked up and said, "I don't have to."
She said, "What do you mean you don't have to?"
He said, "I opened up my geography book and went in the ocean."
