Keep Calm and Don't Blink
Sure, we may have broken away over 200 years ago, but there are a lot of British things 'mericans love. Shakespeare. Monty Python. Lion bars. Hitchhiker's Guide. Moggies. Did we say Lion bars? Mmm. Lion bars. Note to self: don't write copy while peckish.
We love us some good contingency planning. And Britain has that in spades. When everything goes all pear-shaped, there's a plan for that. Nazis taking over? Yep. We got the poster. London overrun by Weeping Angels? You bet. Get your caffeine and cartoon toothpicks right here.
