A video of a NBA referee dancing to "Gangnam Style" has been gaining attention.

Psy's "Gangnam Style," which was first released 6 months ago, still has not died down in terms of popularity.

A video on YouTube titled, "NBA Referee Dances Gangnam Style VS Mascot" was uploaded.

In the video, during a break, the NBA team mascot and the referee battle one another with the 'horse-riding' dance.

The referee then takes off his shirt and dances to the song, while fans and players watch in awe.

On the other hand, Psy hit a billion views on his video on December 21.
