An old couple drive through town and stop by the diner where they first met. As they delve into nostalgia, the topic moves to the first time they made love and it happens to be by the fence behind this very same diner. “How about going back there for old times sake?” asks the old man, with mischief in his eyes. To his surprise, the wife says, “Let’s go for it!” and they proceed to walk out through the backdoor.
All this while a guy hears the whole conversation from the adjacent booth. “It would be interesting to see how the oldies get it on”, he thinks with a chuckle and also walks to the back of the diner.
From behind the garbage cans, he sees the old couple undressing clumsily. The busybody’s grin slowly turns into amazement as he sees the two having the most amazing s*x he has seen in his entire life. 30 minutes later, after they are fully clothed, he approaches them with an apology and asks, “I don’t want to interrupt, but I was at the adjacent booth from the diner and I am amazed to see you both in action; even after 50 years of marriage.”
The old man replies, “Son! You want to know the secret? Fifty years ago, that fence wasn’t f**king electrified”
