A young bloke goes into a chemist shop to buy some condoms .
An experienced shop assistant serving him asks , What size ?
Well , I don't know , how do I find out . Well there's a fence out the back with
some holes in it , try them  , then come back & let me know .
The bloke goes out the back , as does the unlucky for love shop assistant .
The young bloke trys all the holes . Comes back into the pharmacy . Well ,
what size are you ? He says Forget the condoms , How much for the fence .
