Participants in the 13th "No Pants Subway Ride" travel on an Underground train in London on Sunday, January 12. The annual event first started in New York City in 2002, when one pantsless participant boarded a subway at each of seven consecutive stops, claiming to have forgotten his pants. Since then, cities all over the world have seen bare-legged patrons on subways. LEON NEAL/AFP/Getty Images
