The No Pants Subway Ride is an annual event staged by Improv Everywhere every January in New York City. The mission started as a small prank with seven guys and has grown into an international celebration of silliness, with dozens of cities around the world participating each year.
The 13th Annual No Pants Subway Ride took place on January 12, 2014 in over 60 cities in over 25 countries around the world.
