French prankster Remi Gaillard is behind a bat costume prank video on YouTube. In the video, Gaillard dresses up in a bat costume and scares unsuspecting people in various situations and locations, including parking garages, public restrooms, elevators and subways. In one clip, he sneaks up on a man at an ATM and winds up getting pushed into the street. In the final scene the giant bat runs into a police officer, who doesn't appear to find the prank funny.http://www.youtube.com/watch?v=g1dxNsjYeIs
