Plan B, a MN-based Guerilla Improv Group hosted the No Pants Subway Ride on Sunday afternoon, gathering at the Mall of America transit station. The NPSR was started in 2002 by Improv Everywhere in New York as a prank, and has become an annual, global event. 65 riders boarded the Metro Transit Light Rail shortly after 1 p.m., and proceeded to take off their pants after the first stop. The pant-less riders were instructed not to mention the prank as clothed and bewildered onlookers asked questions and stared. The riders finally exited into the 8 degree wind at Target Field to pose for a photo and board the next train back to the Mall. PHOTOS BY B FRESH PHOTOGRAPHY on January 13, 2013.
