KTIV News 4 Sioux City IA: News, Weather and SportsTrain commuters take part in annual no pants ride

Train commuters in major cities around the world got a little cheeky Sunday as part of the annual "no pants subway ride".
    The pranksters were asked to converge at train stations wearing everything but their dungarees, and act nonchalant.
    New York-based Improv Everywhere says it started the No Pants Subway Ride in New York 10 years ago.
    It says cities, including New York, London, Mexico City and Tel Aviv took part in Sunday's rides.
    The group says it has no political agenda -- the goal is to get people to laugh
