Question: How do you fight someone possessed by a demon?

Answer: I don’t know, but make sure someone is recording it so the police don’t think you’re just assaulting some girl.

Case in point: the video below, which shows a girl freaking out on a subway train (Is she on drugs? Maybe, although saying she’s possessed by a supernatural entity is probably as apt.). During said freak out, the girl attacks a hapless passenger nearby who was simply trying to eat some Pringles. What ensues is a classic example of why riding the subway can sometimes suck.

Now, having watched the video, what would you have done if you were attacked?
