The latest round of "knock out" was played right in the nation's capital. The women reported being punched right in the face by a bicyclist. The dangerous game played by teens has been spreading across the states. "I was shocked at the whole narrative of it," a 50-year-old Pittsburgh teacher told Fox. A group of boys knocked him out in 2012. While he does not remember the moment, he said the footage spoke for itself: "Boom came the punch and down I went. Straight down with my face falling and hitting the cold concrete."
