The video starts with one person, often masked, dancing while everyone else in the room pays no attention but when the chorus kicks in they all join in, usually wearing crazy costumes or with props like blow-up giraffes or bicycles.
YouTube said the craze appeared to have started with a posting by a vlogger and spread quickly, with more than 12,000 Harlem Shake videos posted from the start of the month to mid-week watched up to 44 million times.
Harlem Shake has a way to go to top Gangnam Style which made history last December when it became the first ever video on YouTube to reach 1 billion views.
But latest figures show one office version of Harlem Shake has received over 10 million hits while an underwater version by University of Georgia’s men’s swim and dive team has 7.8 million hits.
The Museum of Natural History in Halifax, Canada, has jumped onto the bandwagon, with its staff donning hats in front of a stuffed moose and carrying Granite the Python in their version.
Curator Jeff Gray said the video was part of the museum’s educational outreach (here).
