Forget Gangnam Style, the Harlem Shake is the new online dance craze you need to know about.
And to teach you, here are our five favourite videos demonstrating how to do the dance (which was inspired by a track by Baauer):
The TSCS Edition
The Portland Edition
The Shaytards Edition
The Firefighter Edition
The Office Edition
So there you have it, all you need is one crazy dancer who does a short solo before a bunch of crazy dancers join in. Simple!
