You're in Antarctica at a research base and a dog comes sprinting out of the whiteness pursued by a helicopter with a crazy Swede (actually, they're Norwegian, Mac) taking shots at it from a high-powered rifle. What do you do? Do you try to understand what the crazy Swede is doing trying to kill this dog, or do you stupidly shoot the frantic foreigner in the head and give the mutt a friendly pat? If you answered to the latter, well, bad luck - because you're about to be "assimilated" by an alien life form. Should have learnt to speak Swedish (I mean, Norwegian!...).
