How to Know You're in a Movie, Part 2

In case you can't find any people with serious gunshot wounds, an alternative way to find out if you're in a movie or not is to locate an alien, a demon, a mutant or a robot who wears a rubber mask in order to appear human. Once they've taken the mask off, you'll have your answer instantly. Here's how:

Aww, he looks like a nice guy!

Oh no, now he's pissed! Watch out, he's taking his mask off! What could he possibly be hiding under there???

Scenario A: Well this makes a lot of sense. Without the mask his head looks slightly smaller, which means this is real life. I, for one, welcome our new alien/demon/mutant/robot overlords.

Scenario B: Huh. He's actually bigger without the mask. I guess this is a movie after all. Let the alien/demon/mutant/robot ass-kicking commence!
