Although I've long thought that very witty smartassing was one of the British National Pastimes, my vote is going to that Far-Flung Heathen, MOWOG.
Three of his latest jokes I can remember: the Isle of Mann banning lawyers; changes being allowed on the basis of safety because the cars are so slow, they're liable to get rammed from behind; and today's wing nuts prevalent as F1 fasteners.
I'm expecting the Brits here to step up, defend your National Wit Honor, and make this place a lot funnier. To many of the arguments here are posed as though the collapse of the Local Space Time Continuum (Back to The Future II) hinges on their resolution.
