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 ago? 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 devil, that sounds like a good idea," she answers. > >There's a police officer sitting in the next booth listening to all >this, and 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 no 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 pt'>>couple struggles to their feet and put their clothes back on. The >policeman, still watching thinks, that was truly amazing. He 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 must have been having 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."
