I know what it is - a two inch by four inch piece of wood - my father works somewhere where they get through tons of it.   What I meant was that I've not heard the expression "clue by four" here in the UK, perhaps partly because we're all supposed to be converting to metric measurements like good little European Union boys and girls.

Ah, but we drive on the correct side for historical reasons - ride your horse on the left, fight your enemies with your sword in your right hand.   As for the Euro - why would we want to use stupidly-named Monopoly money when we've got £ Smith?  I will agree on metrication, though - imperial measurements are interesting but tricky, it's the Big Brother behaviour of the EU telling us that we must convert that we don't like.  We've survived as an island nation this long by being bloody-minded and stubborn - we beat you when you lot were being conned by Boney, we beat the Spanish Armada, we stopped the Germans in their tracks in 1940, so we don't take well to being told what to do.

Well, having a moat certainly helps big time when the forces of evil come a-knocking at the castle gates. 

No doubt Sir BlackKusanagi will be overwhelmed,
      but this month's Goddess of AMG is . . . Monica Martin.
