[ There is no polite way to describe the way Mouse goes about pantomiming a donkey punch (http://en.wikipedia.org/wiki/Donkey_punch). Nor is there any polite way to explain the sort of faces that he makes or the sound effects that he provides. All you need to know is that there is grunting, there is flexing of scrawny teenage boy arms, and then there is the proverbial thwack (punctuated by Mouse's very best impression of Shy Ronnie, of course). ]
