Bros Fake Zombie Apocalypse For Drugged Sister's Ride Home From Surgery

When fleeing zombies, don't forget the cat or the funfetti cake.

Let’s face it: Those “kids acting funny after dental surgery” videos are a little played out.

That is, until these two brothers put a fresh and mildly cruel spin on the whole thing -- convincing their little sister that a zombie apocalypse is afoot.

They really went to elaborate lengths to make it seem somewhat realistic, too — creating fake radio announcements and staging phone conversations with their parents.

Not only did they fool their sister, they also learned her true feelings about the family pets.
