"Don't touch my exoskeleton!" is probably what the silent but pissy alien from Indepedence Day was telepathically screaming as Dr. Brackish Okun sliced in to reveal his puny self. Whether the loony doc could hear him is a different story, but the warning was there -- and when you touch another man's exoskeleton, expect hell. With one cut, the alien leaps into action, strangling Okun and using him to vocally explain to the President that he and his kind aren't here to sing Kumbaya.
