If I recall my O'level physics, absolute zero is -273 C. I don't know what that is in the now defunct F scale but I would imagine it to be a lesser number. A good joke though.

You'd have a point there Tom. See that's why I gave up physics and concentrated ongeology instead...it's much more of a wooly subject and you can get away with lil mistakes (or large ones like lots of expensive holes into rock that contains no oil...as we seem to be doing at the moment arf arf arf)
