In a tavern in Sandpoint, Idaho...

... a husband leans over and asks his wife, "Do you remember the first time we had sex together over 50 yrs ago?

We went behind this very tavern where you leaned against the back fence and I made love to you."

"Yes, she says, "I remember it well." "Ok," he says, "How about taking a stroll around there again and we can do it for old time's sake?"

"Oh, you old devil that sounds like a crazy, but very good idea!"

There's a police officer sitting in the next booth listening to all this, and having a chuckle to himself. He thinks, "I've got to see these two old-timers having sex against a fence. I'll just keep an eye on them so there's no trouble." So he follows them.

They walk haltingly along, leaning on each other for support, aided by walking sticks. Finally they get to the back of the tavern and make their way to the fence.

The old lady lifts her skirt and the old man drops his trousers. As she leans against the fence, the old man moves in.

Suddenly they erupt into the most furious sex that the watching policeman has ever seen. This goes on for about ten minutes. Finally, they both collapse panting on the ground.

The policeman is amazed. He thinks he has learned something about life that he didn't know.

After about half an hour of lying on the ground recovering, the old couple struggle to their feet and put their clothes back on.

The Policeman, still watching thinks this was truly amazing. I've got to ask them what their secret is.

As the couple passes, he says to them, "Excuse me, but that was something else. You must've had a fantastic sex life together. Is there some sort of secret to this?"

The old man says, "Fifty years ago that wasn't an electric fence!"
