For old time sake

A husband leans over and asks his wife, "Do you remember the first time wehad sex together over fifty years ago?
We went behind this very tavern where you leaned against the back fenceand 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 doit for old time's sake?"

" Oh Charlie, 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 tosee 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 forsupport aided by walking sticks.

Finally, they get to the back of the tavern and make their way to thefence. 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 theyerupt into the most furious sex that the policeman has everseen. This goes on for about ten minutes while both are making loud noisesand moaning and screaming. Finally, they both collapse,panting on the ground.

The policeman is amazed. He thinks he has learned something about life andold age that he didn't know.After about half an hour of lying on the ground recovering, the oldcouple struggle to their feet and put their clothes back on.

The Policeman, is still watching and thinks to himself, this is trulyamazing, 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. Isthere some sort of secret to this?

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