A man in a restaurant overhears an elderly couple next to him celebrate their 50th wedding anniversary.
"Dear do you remember 50 years ago when I proposed to you right here in this same spot?" the old man asks caressing his wife's hand.
"Yes honey I do remember." she replies smiling.
"Do you remember after you said yes we went out back and made passionate love?" he asks with a devilish grin.
"Oh yes I remember." she answers coyly.
"Want to do it again?"
The younger man overhearing this watches as the old lady nods enthusiastically and grabbing their canes the elderly couple head out the back entrance. Glancing around to see if anyone else has noticed he decides to follow them, not believing what the elderly couple are doing.
He peeks out the back door into the ally and freezes in astonishment at what he observes. The old lady is bent over grabbing a fence with her dress hiked up while behind her the old man has his trousers around his ankles and is thrusting vigorously. The old couple scream and moan as they make wild passionate love for over 30 minutes finally collapsing to the ground covered in sweat, their chests heaving from the exertion.
The young man rushes up as the elderly pair lay gasping and exclaims, "My God are you alright? I don't want to seem like a pervert but I am in shock how after 50 years and at your age you can still make love like that!"
The grey haired lady tries to compose herself, smoothing out her dress she looks up from the ground and haggardly replies,"You're in shock? 50 years ago that fucking fence wasn't electrified!"
