Improv Everywhere, a New York based organization dedicated to causing public scenes, struck its city with a good one last week.
Over 3,000 randomly selected participants were given an .mp3 file to download. The file contained a list of instructions delivered by an omnipotent voice.
At 6:00 p.m., everybody simultaneously clicked play.
At the same time, 3,000 people went from shopping to folding clothes, to slow dancing, to high-fiving and, eventually, to standing still.
The voice then directed everybody outside to Bryant Park, downtown Manhattan, where an epic mummy party commenced.
