Today was marred by violence this morning as a man wielding a knife invaded Rockefeller Plaza!
Ch-ch-check out the video (above) to see footage of NBC's crack security team shutting down the man's apparently self-harming intentions!
Host Matt Lauer was on the scene and tweeted just moments later:
Matt and company continued their thanks later on the air. See them tell their whole story …AFTER THE JUMP!!!
