Jogger finds a tennis ball So Joe is out jogging alongside a tennis court. Unspurprisingly, he spots a tennis ball which has gone over the net. It's getting late and nobody's left playing, he figures they just left the ball there. So Joe picks up the ball and puts it in his shorts pocket, to play with his dog later. He runs off, and stops by his regular watering hole to rehydrate. One of his friends spots the bulge in his shorts and asks: ""What have you got there Joe?"" ""That? That's a tennis ball."" ""Dear lord, and I thought having a tennis elbow was bad!""
