The United States of America, should convert to the metric system.
Why do you ask? Because it's a better system, and it would satisfy Europeans and notable others, who apparently have nothing better to do than to insult and make fun of Americans on this very trivial matter.
How it personally affects and offends them, would be the question of the year. Maybe they are as oversensitive as Sheldon Cooper( the nutty, arrogant genius, that has ego and superiority complex that would understandably bring harm to himself in the real world), or maybe they are in desperate need of getting some snoo snoo. I don't know, and I don't really care.
Convert us over Mr. Obama, if you have the time ofcourse....
