Interesting post from Shaarique on Serendipity. The post says it all!
A girl reacts as participants ride the train in the annual “No Pants Subway Ride” in New York January 13, 2007. The event is run by the group Improv Everywhere, and is intended to make people laugh and have an interesting New York experience. When asked, participants are not supposed to reveal the purpose, they are asked to respond with something such as, “I forgot my pants today.” [Reuters]
