At a jewellery store, an old man bought an expensive locket as a present for his girlfriend.

“Don’t you want her name engraved upon it?” asked the jeweller.

The Old man thought for a moment, and then, ever the pragmatic steadfastly replied,

“No, just engrave it:

To My One And Only Love.

That way, if we break up and she throws it back to me in anger, I can use it again.”
