One time, back in the day, a boy named Johnny was walking to school with his girlfriend. He was trying to impress her, so he said, "I bet you I can push my father's outhouse into the river."
She didn't agree with him, so he proved her wrong. Impressed, she walked the rest of the way to school hand in hand with Johnny. That day at school, they studied the story about George Washington and the cherry tree. The moral that they learned was "never tell a lie."
After school, Johnny went home. When he walked in the door, his dad met him. He said, "Son, did you push my outhouse into the river?"
Johnny said, "Dad, I want to be like George Washington and never lie, yes, I did."
And his dad beat him from one end of the house to the other. You could have read the newspaper off of Johnny's rear end.
After Johnny was finished sobbing, he asked, "Dad, why did you whoop me? I didn't lie. George Washington cut down the cherry tree and didn't lie about it, and he didn't get a whooping."
Johnny's dad looked at him and said, "Son, I bet George Washington's dad wasn't sitting in that cherry tree when he cut it down, was he?"
