Man's vid of NYC subway-step fail gets city's attention fast

When Dean Peterson noticed that he and his fellow commuters kept tripping over the same subway-station step, he didn't get mad. He got his camera. "[My girlfriend and I] just thought we were kind of klutzy," Peterson said. "But then I...noticed that other people were doing it too." The Brooklyn man filmed a series of people stumbling as they left the Sunset Park station, set it to a ragtime-ish soundtrack and posted it online. Less than 12 hours -- and now more than 486,000 views later -- the MTA responded by blocking off the stairway and prepping it for repairs. See? Watching all those viral videos can serve a purpose.
