Sweet Old Love

A husband leans over and asks his wife, 'Do you
remember our first time 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'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.  As she leans against
the fence, the old man moves in.. Then suddenly they erupt into the
most furious love making that the policeman has ever seen. This goes on for about
ten minutes while both are making loud noises and screaming. 

Finally, they both collapse, panting on the ground. 
 
The policeman is amazed. He thinks he has learned
something new about life and old age. 
 
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.'
