Also discovering that the American 2nd Amendment, The Right To Bear Arms, isn't actually for hunting, or to protect themselves from Native Americans back in the ol' Wild Wild West. Which as far as I'm aware, is what everyone thinks it's there for.
It's because they were fucking shit scared of us British coming back and being kind of angry about all that tea they dumped into the harbour, and they also sort of stole it from us because back then it was sort of one of our laws and then we got all uppity about one school shooting and banned handguns, although we haven't actually had one since. Anyways I'm veering off my point here.
Edit: Although I'd like to point out, I'm not sure why they were worried, since we'd been proper fucked up by the French because they're bloody gits.
