The husband leans over and asks his wife, 'Do you remember the first
time we made love 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 “I've got to see these two old-
timers up against a fence. I'll just keep an eye on them so
there's no trouble”. And 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.
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 their 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.'

Great one.
