New York City-based prank collective Improv Everywhere has been pulling off large-scale stunts for some time now. The No Pants Subway Ride is one of the many they do every year that catches the public off guard. The most recent finds the group inside GAP’s Fifth Avenue flagship location tricking the customers and staff by posing as the store’s mannequins.

It was all in good fun, and people actually believed they were dummies. That was until one GAP employee ruined the fun and snitched on these good for nothing pranksters by calling the cops. Nobody got hurt, and all they got was just a slap on the wrist.
