New York - Hundreds of men and women around the world “dropped trou” recently in celebration of the 18th annual No Pants Subway Ride, reports the Association of Mature American Citizens. Immodestly clad in panties and scanties, young folk and old from New York, the flagship city, to the far reaches of the globe they boarded London’s Tube, Tokyo’s Metro, Berlin’s U-Bahn and Lisbon’s Metropolitano for a near-nude fun fest. 

New York-based comedy collective, Improve Everywhere, established the event in 2002 and it went viral across the planet. Their aim: “to surprise and delight random strangers through positive pranks.”
