Sir Ian Wilmut, the scientist who cloned Dolly the sheep successfully made a clone of himself and took it down the pub to show off.
The clone goes up to the bar and shouts, "Hoi! Big milky-titted barmaid, get me a pint!"
The clone gets his pint and swaggers across the pub, pinching women's arses, giving their boobs a wee jiggle and saying filthy suggestions to them on the way back to Sir Ian, who is sitting there thoroughly embarrassed.
Sir Ian decides there and then to do away with his creation and leads him up to the highest building he can see and pushes it off the edge.
Sir Ian gets back down to the bottom and is swiftly huckled by the police.
"I suppose I'll be doing life for murder." he says, resigned to his fate.
"No" the policeman says, "We're arresting you on suspicion of making an obscene clone fall."
