"Improv Everywhere" is a New York City-based prank collective that causes scenes of chaos and joy in public places.

For their latest mission, They recreated the famous "triple dog dare" scene from A Christmas Story on an NYC subway car. Instead of licking a flagpole, our character licked a subway pole. Using a prosthetic tongue with a magnet inside, we were able to get his tongue to appear stuck to the pole, much to the surprise of New Yorkers on the train.
