“Improv Everywhere is a New York City-based prank collective that causes scenes of chaos and joy in public places. Created in August of 2001 by Charlie Todd, Improv Everywhere has executed over 100 missions involving tens of thousands of undercover agents.”
For the Second Annual Black Tie Beach, hundreds of participants spent a day at Rockaway Beach in black tie attire. They covered a half mile-long stretch with a diverse group of people of all ages laying out, playing games, and swimming in the ocean in formal wear. “Agents” were instructed to find cheap tuxedos and ball gowns at thrift stores for the occasion. The event also happened on the same day in five other cities around the world, including Sydney, Australia and Malmö, Sweden. See a 2-1/2 minute video and a selection of more photos here. (One of the pranksters was 90!)
