Hitch-Hiker

A girl hitch-hiking along the motorway was picked up by a lorry driver... She was a good-looking girl with big tits and short skirt and after a while the lorry driver noticed that he'd developed a thumping erection.

When he showed it to her she produced a bread knife from her hand bag, cut off his cock and tossed it out of the window. Now it just so happened that a couple of Irishmen were driving along in the car behind, and when the severed penis landed on the windscreen with a liberal smattering of blood, Paddy, the driver, turned on his windscreen wipers, swept it away and said:" Jaysus Mike, did you see the size of the cock on that fly!!!!"
