Don't you think it's funny that the United States was one of the first colonies to fight a war and die to be independant of the Brittish Empire, yet they're one of the last countries on the planet still hanging on to the Imperial system of measurement.
It would be "funny" if the one had anything to do with the other; you know, if the American Revolution had been a revolt against a system of weights and measures then yes, it would be "funny".
You can keep your arbitrary, based-on-nothing, only-divisible-by-2-and-5, French-sytem-imposed-by-law-with-long-winded-dorky-sounding-unit-names.
