Maybe it was double coupon day.

A video of a woman in China who appears to be the victim of some sort of demonic possession has gripped the internet and set off a debate about what actually happened.

The woman contorts her body and falls the floor while other stunned shoppers look on and come to her aid, eventually helping her walk away.

Some people think the woman is possessed, while others say she's having an epileptic fit. The true skeptics out there believe the whole thing was just staged because, apparently, people will stage things for attention on the internet (crazy, right?).

And here you were thinking the only time people lost their minds in supermarkets was when they got stuck behind the old lady in the express aisle trying to pay for her bottle of Geritol by check.
