An obnoxious system of measurement that, contrary to popular belief, Americans know, but don't see the need to waste billions, or time, on implementing. The metric system uses decimals and units of ten because fractions are just so much more convenient than whole numbers.
Canadian: Americans are too stupid to use the metric system.
American: Did you write that on the internet?
Canadian: Of course, stupid American.
American: Why didn't you use that global system of interconnected computer networks that Canadians invented?
