How about a good joke?
There was a boy who had to live with his grandparents, and all they had to use the bathroom was an outhouse next to a river.
The boy hated that outhouse. It stunk in the summer and was frezzing in the winter and was swarming with bugs.
So he decided he was going to get rid of it. He waited till a good rainy day had made the water of the river rise and soften the ground, and then gave it a hard push and nocked it into the river. He felt really good as he watched it float down the river.
Later that day when he got home he found grampa there waiting for him and he didnt look happy. He ran up to grandpa and said he was sorry for pushing the outhouse into the river, but he just couldn't use it anymore. He told his grandpa how when George Washington was young he chopped down his dad's cherry tree, and since he told his dad the truth he wasn't punished.
After hearing this his grandpa game him a long hard look and told him that George Washington's dad wasn't in that cherry tree when it was nocked over.
