Oh, Canada.

The United States and Canada don't always see eye to eye, or "eh" to "eh." But when the chips are down, Americans know they can always count on Canada to have our back.

That fact was on full display in Toronto Tuesday night, when the mic cut out while a girl was singing the U.S. national anthem at the start of a Maple Leafs' game. Instead of mocking the girl with laughter or a group chant of "anthem fail!", the Canadian crowd stepped up and finished the song without missing a beat.
