Back when Ted Turner ran a network, he commissioned a video to be shown if and when the world was ending. It apparently featured the Air Force band playing Nearer My God to Thee at a slow tempo. The same song that the band played on the deck of the Titanic. Pretty boring stuff.
John Oliver had something to say about it in 2015 and he created an alternative video to be played at the end of the world. I don't know that we're there yet, but when it comes we might be busy and the internet might be down. So watch it now. It will be the funniest thing you see today.
