Do you think we're fools? We know of your "secret" plans to invade the US and escape the horrors of your tundra-plagued landscape. We'll be more than ready when you make your move.
Fools. We're already making our move. We've been infiltrating the US for decades. We send down Doctors, Nurses, Lawyers, Computer Scientists, Actors, Comedians and more, all insinuating themselves into the fabric of American culture waiting for the day to take control.
The only problem is that with all our smartest people heading to the States, there is no one left up here to make the decision.
