The husband leans over and asks his wife, 'Do you remember the first
time we had sex together over fifty years ago? We went behind the village
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 Jim, you old devil, that sounds like a crazy, but good idea!'

A police officer sitting in the next booth heard their conversation and, having a chuckle to himself, he thinks to himself, 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.

The elderly couple walks 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. Then suddenly they erupt into the most furious sex that the policeman has ever
seen. This goes on for about ten minutes while both are making loud noises and moaning and screaming.
Finally, they both collapse, panting on the ground.

The policeman is amazed. He thinks he has learned
something about life and old age 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 is still watching and thinks to himself, this is truly amazing, I've got to ask them what t heir secret is.

So, 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?'

Shaking, the old man is barely able to reply, 'Fifty years ago that wasn't an electric fence.'
