BERLIN, GERMANY - JANUARY 12: A participant of the No Pants Subway Ride reads an e-book next to another participant on a train on January 12, 2014 in Berlin, Germany. The annual event, in which participants board a subway car in January while not wearing any pants while behaving as though they do not know each other, began as a joke by the public prank group Improv Everywhere in New York City and has since spread around the world, with enthusiasts in around 60 cities and 29 countries across the globe, according to the organization's site.
