My (last) Friday Yuk
Two country bumpkins were sat in a pub having a beer. One was telling the other about the new flame he had met. He was saying that she was a local girl from the next village and that the rumour was that, at 24, she was still a virgin.
"Well Harry", the second man commented, "I'd make sure if I was you...there ain't many virgins left round these parts."
"How do I go about finding out then, Fred?" asked the first.
"Well, if I was you, I'd be getting one of they new-fangled virgin detector kits."
"A virgin detector kit? How does that work then?", Harry asked.
"Well", said Fred, "a virgin detector kit comes with three pots of paint and a paintbrush. You paint half your todger green, half your todger red and you paint the knob blue."
"And?", replied Harry enquiringly.
"Then, when it gets to that time when you are starting to get a bit friendly, whip out the 'old man' and show it to her. If she says she's never seen one like that before....she probably ain't no virgin!!!"
