While he was out jogging in the park one morning, a man found a brand new tennis ball on the ground.
He looked all around him and seeing that nobody else was in sight, he picked the tennis ball up and tucked it into the pocket of his shorts.
Later, on his way home, he stopped at a pedestrian crossing and waited for the lights to change.
A young girl who was standing next to him at the crossing, couldn’t help but notice the large bulge in his shorts.
“What’s that?” she asked, pointing at his shorts.
“Tennis ball”, came the breathless reply.
“Oh my gosh”, the girl remarked sympathetically. “That must be very painful. I had tennis elbow once!”
