An elderly woman talks to passengers in underwear in the Sofia City subway as they take part in the 2014 No Pants Subway Ride on January 12, 2014 in the Bulgarian capital. Started by Improv Everywhere, the goal is for riders to get on the subway train dressed in normal winter clothes (without pants) and keep a straight face.
