Teachers at Westwood Jr./Sr. High School surprised students at a pep rally with a choreographed dance to Gangnam Style.
A music video for the song, by South Korean performer Psy, has garnered more than 500 million views and numerous imitations on Youtube.
Westwood Spanish teacher Jen Kavanagh organized the dance for Friday's pep rally. A student filmed the dance and later posted it online.
The dance was apparently effective, as the Cardinals went on to a 39-6 win over Pascack Hills that night.
