Jan. 8 (UPI) -- Commuter trains in New York and around the world were filled with disrobed passengers for the 2018 No Pants Subway Ride.
The global event, which began in 2002 as a prank by New York group Improv Everywhere, featured hundreds of strap-hangers in more than 60 cities braving sometimes frigid temperatures to ride the rails in their skivvies.
The No Pants Subway Ride -- or, as its known in Britain, the No Trousers Tube Ride -- took place Sunday in more than 60 cities, including New York, London, Chicago, Los Angeles, Jerusalem, Berlin, San Francisco, Montreal and Lisbon.
The temperature in New York during Sunday's event was only 17 degrees, while Chicagoans dropped their pants with temperatures in the mid-20s.
Participants in Montreal may have faced the worst conditions Sunday, with a temperature of 0 degrees.
