'Walking Dead' Zombie Subway Grate Prank Terrifies New Yorkers

Though it seems like a bad idea to be standing downstream of an intensely frightened person (some of us are wetters), everything else about the latest NYC horror prank is spot-on. To promote the new season of The Walking Dead, a mastermind marketing team sent a subway-grate full of extras through hair and makeup before placing them below Union Square in Manhattan. The rest ensures that we'll always walk around the subway grate from now on.
