An elderly couple is enjoying an anniversary dinner together in a small

>tavern. The husband leans over and asks his wife, "Do you remember the
>first time we had sex together over fifty years a go? We went behind
>this tavern where you leaned against the fence and I made love to you."
>
>"Yes," she says, "I remember it well." "OK," he says, "how about taking
>a
>stroll round there again and we can do it for old time's sake.
>
>"Oooooooh, Henry, you old devil, that sounds like a good idea," she
>answers.
>
>There's a police officer sitting in the next booth listening to all
>this,
>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 not any 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, takes her
>knickers down and the old man drops his trousers. She turns around and
>as she hangs on to the fence, the old man moves in.
>
>Suddenly they erupt into the most furious sex that the watching
>policeman
>has ever seen.
>
>They are bucking and jumping like eighteen-year-olds. This goes on for
>about forty minutes! She's yelling, "Ohhh, God!" He's hanging on to her

>hips for dear life. This is the most athletic sex imaginable.
>
>Finally, they both collapse panting on the ground.
>
>The policeman is amazed. He thinks he's 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, "that was truly amazing -- that old
man
>was going like a train-I've got to ask him what his secret is."
>
>As the couple pass, he says to them, "That was something else. You had
>sex
>for about forty minutes. How do you manage it? You must have had a
>fantastic life together. Is there some sort of secret?"
>
>The old man says, "Fifty years ago that wasn't an electric fence."
