During the 11th annual No Pants Subway Ride subway riders throughout New York, London, Washington, Toronto, Mexico City and dozens of others nonchalantly stripped to their underwear from the waist down Sunday afternoon.
It was a part of a global practical joke coordinated by prankster outfit Improv Everywhere. The first No Pants Subway Ride took place in 2002 with seven riders. Over the years, the act seems to have become infectious. Now at its eleventh edition, the No Pants phenomenon has spread across the the world and people take part in at least sixty cities across the globe.
