An old man leans on his cane and says to his wife, “Do you remember the first time we made love 50 years ago? We went behind this very building where you leaned against the fence and we made love.”
“Yes,” she replies, “I remember it very well.”
“OK,” the man says, “let’s take a stroll and see if we can do it again for old time’s sake.”
“Oh, you old devil,” says the wife, “that sounds crazy at your age, but let’s try.”
A police officer nearby hears their conversation and, chuckling to himself, thinks, “I have got to see these two old-timers having sex against a fence, just in case he has a heart attack.” He follows them.
The elderly couple walks slowly, leaning on each other for support, aided by walking sticks. Finally, they reach the fence and partly undress. As the wife leans against the fence, the old man moves in. Suddenly, they erupt into the most furious sex the policeman has ever seen. This goes on for 10 minutes with both making loud noises, moaning and screaming. Finally, the man and the wife 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 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 truly amazed. “I have to ask them what their secret is,” he says to himself. As the couple passes, he says to them, “Excuse me but that was fantastic. You must have had a wonderful sex life together. Is there some secret to this?”
Gasping, the old man replies. “50 years ago, there wasn’t an electric fence.”
