There's probably a point where a prank turns into something a bit too scary.
The jokesters at PrankvsPrank went all out with their latest effort, dressing up hordes of helpers like real 'Walking Dead' stylezombies and letting them loose on the local population.
Their make-up and special effects were so good a lot of people looked like they genuinely feared for their lives, including a few small children.
It's quite impressive how realistic it was, and it is funny, but we almost feel sorry for the poor people who must've thought they were in the midst of a '28 Days Later' style apocalypse.
