8. Cinco de Mayo is actually NBD
Every May 5, Americans drink margaritas and wear sombreros, eat guacamole, and just assume that their neighbors to the south are doing the same. Reality check: they aren’t, and they think you look stupid. Not at all Mexico's Independence Day, Cinco de Mayo is a very, very minor celebration to highlight the Mexican army’s underdog victory over French troops at the Battle of Puebla. It'd be like Canadians going crazy over Patriot's Day. Actually, Canadians don't get crazy. Bad analogy.
9. Meteorites are illegal
Essentially, anyway. In 2014, the government passed a law requiring federal protection against space threats, most specifically, meteorites. This all came after the Chelyabinsk meteor scared the living crap out of the Ural region of Russia in 2013. Hopefully, Bruce Willis and Ben Affleck learn to speak Spanish before the next Armageddon approaches.
