While having drinks in a bar in their old neighborhood, an elderly husband leaned over and asked his wife, "Do you remember the first time we had sex together, over fifty years ago? We went behind this very tavern, where you leaned against the back fence and I made love to you." "Yes," she said. "I remember it well."

"OK," he said, "How about taking a stroll around there again and let's do it there again, for old time's sake?"

"Charlie,- you old devil, -it sounds crazy, but why not?"

A police officer, sitting in the next booth listening to all this, chuckled to himself. He thought, "I've got to see these two old birds in action.I'll just keep an eye on them so there's no trouble." So he followed them.

The couple walked haltingly along, leaning on each other for support,Finally, they got to the back of the tavern and made their way to the fence. The old lady lifted her skirt, and the old man dropped his trousers. As she leaned against the

fence her husband moved in.

Suddenly, they erupted into 'most furious sex the spying policeman had ever encountered. The action went on for what seemed to be at least 10 minutes. Loud noises, moans, groans, grunts and sighs were emitted from both partners. Finally, they both collapsed, exhausted, on the ground.

After half an hour of lying there, trying to recoverr, old couple struggled to their feet, re-arranged their clothing and started to leave.

The policeman said to himself, "I've got to find out what their secret is".As couple passed, he said, "Excuse me, -I happened to see that, and I must say - it was truly amazing! You must have had a fantastic sex life together.Is there some sort of secret to your ability to perform like that?"

The old man replied, "Well - fifty years ago that wasn't an electric fence".
