For Improv Everywhere latest mission, pedestrians in a busy New York crosswalk begin ballroom dancing one by one as they “accidentally” bump into their partners. This project took place on the crosswalk in front of Penn Station on 7th Avenue, one of the busiest spots in the city. They have staged the mission over and over again, with the performance repeating at each change of the light and always finishing before the “Don’t Walk” countdown clock reached zero.
