The events of the French train terror attack seem almost too incredible to believe, which is why you really need to watch this video of Anthony Sadler, one of the three men who stopped the attack, describing what happened to Jimmy Fallon on "The Tonight Show." Sadler is incredibly calm while telling his story, which we assume is the kind of attitude that helped him during the attack. Of course, the military experience of his two buddies was probably also a factor, but how many people hearing a friend say "go" when someone is firing a gun would actually get up and follow? One of his friends from the train, Alek Skarlatos, was also just announced as one of the new "Dancing with the Stars" contestants, so they've been having a busy couple of weeks.
