Not A Referee, A King
The NBA has provided several amusing moments, and this one is right there among them. These three referees were diligently discussing their next move when this Budweiser ad decided to crown one of them a king. As you would expect, the camera stayed on them for a few minutes longer than usual, and the audience enjoyed it.
The chosen king looked like he had no idea what was going on, but he probably found out later because it seemed his face was headed in the direction of the jumbotron. The jumbotron is the large screen in basketball courts that displays replays and in-game footage.
