In this needlessly scary YouTube video, a group of reckless teens play chicken with an oncoming subway train. Certainly we don't need to mention how insanely dangerous this is. That's common sense, or at least it should be. (Don't worry. No one gets hurt.)

The five kids jumped onto the tracks at the No. 3 line's Kingston Avenue station, risking their lives with each passing moment. Most of them quickly climbed back onto the platform, but two stayed on the tracks until the lights of an approaching train were clearly visible. Eventually, they use better judgment and get out of harm's way.

Not surprisingly, the MTA takes a dim view of such foolishness. “Playing on or near subway tracks is one of the most dangerous things anyone can do,” said MTA spokesman Charles Seaton, adding that the video will be turned over to the NYPD.
