The Walking Dead is a very serious show, with life-or-death consequences that have viewers glued to their seats whenever it airs on AMC. With that being said, the network decided to see how real New York residents would react if zombie hands suddenly emerged from a sewer grate in an epic prank that sent several unsuspecting pedestrians scrambling. AMC released a video of this prank, showing how they put several actors in zombie makeup and placed them below the street, just waiting for the right victim to walk by. How would you react if several hands sprung up through the street? Hopefully, you'll never know, barring a real zombie invasion or AMC taking this prank on tour, but in the meantime, check out the video below.
