geraint and Patrick were coming out of a pub in Wales one evening when geraint spotted a Sheep with its head stuck in the railings.
"Look at that Paddy, we cant miss a chance like that" says geraint
So geraint walks up behind the sheep, drops his trousers and does this business.
geraint then says "Okay Paddy its your turn next"
So Paddy drops his trousers and stuck his head in the railings......
