An old couple celebrate their 50th anniversary at a restaurant that they used to regularly go on dates to.
It was a particularly fancy establishment and a few drinks into their visit, the elderly husband stood from his seat, looks around and asks his wife, "Do you think we should go behind this place and relive our first time here, like against the fences?"
With a smile and a nod, the wife agrees and they venture outside and into the alley around the restaurant.
Not long afterward, a bike patrol cop rolls past the alleyway and hears the most intense love-making session known to man, the couples' shouts echoing into the street.
He flashed his headlights onto the couple just after they had finished and with a puzzled look, he asked "What are you two doing? I don't think I've ever seen a couple go at it with such passion and intensity in all my years."
The old man, pulling his pants up and buckling his belt, replied, "Yeah, well fifty years ago this place didn't have electrified fences here."
