This might just be the scariest Halloween prank we've ever seen. Or, frankly, any prank we've ever seen. In fact, we're not sure if this is even legal.
Made my Remi Gaillard, a French prankster. Fun fact about Remi: he starting making prank videos on YouTube after he lost his job in a shoe store. Anyway, check out this madness. If you need us, we'll be awake for the next three days.
