No Pants Subway Ride

Usually, we'd advise you to keep your pants on when you ride the CTA, but on just one day each year, it's kosher to take a trip in your undies. Improv Everywhere's annual No Pants Subway Ride got its start in New York City, but the tradition has spread across the world to other cities that have rail-based public transportation options. The Chicago edition of the event takes place on the Red Line, usually boarding at the Loyola Station at noon (check out the official Facebook page for more details about where to meet and what to bring). This year, one lucky participant could take home a new desktop computer for simply stripping down and enduring the bemused stares of strangers. Don't forget to bring a pair of pants—you can't spend the entire day walking around without 'em.
