Americans just have to be different to the rest of the world anyway.
For example, Who else in the world writes dates as month/day/year ?
Also, Ameirca's "imperial" system isn't the same as the imperial system used by the rest of the world when going nostalgic for pre-metrication.
For example, US pints are smaller than the 568ml pints used everywhere else. That makes a glass of beer smaller and that is serious
