A few years ago,(I think in the Tour De France but probably wrong) a couple of riders had a punch up at the end of the stage. They were both skinny climber types and it was clear that neither was a master of the martial arts. The spectacle of two skinny men in Lycra basically slapping hear other with feeling was probably the wimpiest fight ever recorded. Until now, nearly.
So David Cameron mocked Ed Miliband for not being very butch. To be honest, if such things matter at all, it was a little bit pot calling the kettle black. It brought to my mind an image of the pair of them squaring up to each other. Not exactly the Rumble in the Jungle.
