The wife says to her husband "Remember that first night we met here, when you took me outside and we made love up against the farmer's fence round the back in the moonlight? I'd love to do that again Bert"...
"So would I" says Bert...
The man propping the bar up can't believe what he hears. this 80-odd year old couple still at it? Never! So he decides to follow them outside....
What he witnesses over the next 20 minutes is the most frantic, rampant sex he has ever seen, they go at it hammer and tongs, he gives her the pounding of her life, up and down faster than a frog on a bike pump......
Eventually the couple collapse in a heap on the floor, at which point the man who's been watching decides he has to ask them the secret of their fantastic sex life....
The elderly man replies "Well, we first had sex against this fence 50 years ago, and it was fantastic. But the bloody thing wasn't electrified then!"
Rick!
