It's the new, yet old, dance craze: The Harlem Shake.
The dance move has been revived after a YouTube video appeared of a few young men going crazy for a song called 'Harlem Shake' by Bauer.
Most videos seem to do the same thing: In a room of people, one person, often wearing head gear, starts dancing. This one dancer continues to move as the rest of the room ignore him. Then, when Baauer's track begins, the whole room begins to dance.
Here are a few of the best and biggest ones:
Students at The University of Texas gather in front of the iconic clock tower in the main mall.
Employees at the Maker Studios take a break from work to show their moves.
A news team in Shreveport, Louisiana, covers the new fad and then gives their rendition.
The track "Harlem Shake" was released in the summer, but barely became a hit in early February.
The previous dance craze and viral video was by artist, Psy, for his 'Gangnam Style'.
