You’re at the beach and notice a couple in a ball gown and tuxedo. Then another. Then another. Is it a wedding reception in the sand? No, it’s more spontaneous fun with Improv Everywhere

For our latest mission we had several hundred agents spend a day at Coney Island / Brighton Beach wearing black tie attire. We covered a mile-long stretch of beach with a diverse group of people of all ages (from babies to sixty-somethings) laying out, playing games, and swimming in the ocean, all in formal wear. Agents were instructed to find cheap tuxedos and ball gowns at thrift stores for the occasion.
