Occurred on May 17, 2017 / Las Vegas, Nevada, USA
Info from Licensor: "There is a part of the walkway by the MGM in Las Vegas which is blocked off due to construction, but people walk into it very often and then have to go back. This guy was singing to people, letting them know that there was indeed no exit, however most people just ignored him or assumed he was crazy or something. Eventually though, they found out he was right all along."
