Few things are as awkwardly entertaining to watch as when live TV goes wrong. Tuesday night on 'NBC Nightly News,' a fire alarm went off in the middle of the broadcast as Brian Williams was reading a report about American Airlines' bankruptcy. Williams handled the distraction like a pro, pressing on to deliver the news over the noise. It was almost disappointing that he kept his composure and didn't melt-down into a "We'll do it live!" moment, but the video is still oddly hilarious to watch anyway.
