The Lifesaver
 

Two elderly ladies are sitting on the front porch, doing nothing.

One lady turns and asks, "Do you still get horny?" The other replies, "Oh sure I do."

The first old lady asks, "What do you do about it?" The second old lady replies, "I suck a lifesaver."

After a few moments, the first old lady asks, "Who drives you to the beach?

We don't have Lifesavers in the UK, but the joke works equally well if you substitute "Fisherman's Friend". :)
