Myth Creation... "and then he punched a man's head clean off"

This is the moment in the new Rambo film when an ordinary blue collar guy just couldn't sit back any loner and watch the injustice around him. Mostly all he wants is the quiet life but if you piss him off he is capable of punching a mans head clean off. It seems pretty stupid but in its idiocy their is actually a glint of genius. How better could you sum up the sublime in the ridiculous that is another Rambo film than by creating this myth. I.e. the one story that people will tell ( and the irony is all part of it) that carries the meaning of the whole film. Either that or its just my office which as you might imagine is not impartial to the odd You tube link shared by email, where this kind of thing draws a crowd. To create a powerful myth for a product or idea is not easy but when you do its gold.
