First it was "Call Me Maybe." Then it was "Gangnam Style. And now it's the "Harlem Shake."

The newest dance craze has arrived, and the world of sports is all over it.

For those who are unfamiliar, the "Harlem Shake" was an obscure dance move invented some three decades ago that has recently exploded in popularity. The viral videos consist of an individual, usually masked, dancing alone to the song "Harlem Shake" by Baauer. This individual dances for 15 seconds while the rest of the crew stands or sits nonchalantly in the background.

At the 15-second mark, the beat drops and the rest of the crew joins in ridiculous fashion.
