50 Year Anniversary...

An elderly couple was celebrating their 50th anniversary over dinner at their favorite pub; the same pub where they had their first date 50 years prior.

As they're flirting with each other during dinner the old man says to the old woman "Do you remember 50 years ago when I took you out in the alley and had my way with you? Whattya think...for old time's sake?" The old lady nodded in approval and they stood up to head out the side door for some fun.

An eavesdropper at the next table couldn't believe what he'd just heard. These geezers are like 75 years old, NO WAY they're going out in the alley to get it on! I have to see this! So he sneaks outside and hides in the shadows.

Sure enough the old lady faces the fence, hikes her skirt up, grabs hold of the fence with both hands, and they proceed to get it on. Up and down, side to side, bucking like a couple of crazed monkeys. This furious romping continued for about 10 solid minutes before the old man and woman dropped to the ground, rolling around and panting.

As they stood up to walk back inside, the eavesdropper stepped from the shadows and stopped the old man.

"Excuse me, Sir?! I don't mean to be a pervert, but my god, that was amazing! You shagged her ass like a madman for 10 solid minutes! I have to know, what's your secret?!" and the old man replied

"No secret, but I'll tell you one thing. 50 years ago that wasn't an electric fence!"
