Out jogging the other day, I passed the local tennis club.

The fence around the courts is very high, but that doesn't stop some people from lobbing a ball or two over it.

As I jogged past, I found two tennis balls, which I stowed in my shorts pockets.

A bit further on, at a set of traffic lights, I had to wait, jogging on the spot, for the crossing signal.

I saw a young lady, already waiting there, notice the bulges in my short's pockets, with raised eyebrows.

I said to her, "Tennis balls."

She exclaimed, "Oh, how terrible. I once had tennis elbow and it was so painful."
