Passengers strip off as annual No Pants event goes global

Subway riders around the world got an eyeful when their fellow transit users stripped down to their underwear on Sunday for the annual No Pants Subway Ride.

The event, organized by the Improv Everywhere comedy collective, started in 2002 in New York with seven participants.

"We want to give New Yorkers a reason to look up from their papers, from their phones, and experience something that's a little different than their average run-of-the-mill stuff," said Jesse Good, one of the event's organizers.
