Not exactly sure when or how but at some point in time the Harlem Shake experience went viral. The phenomena has invaded Nokia Music and it has now come to your Windows Phone in the form of the Harlem Shake app.
If Wikipedia is right, we can blame a group of five Australian teenagers for this craze. Some of the renditions of the Harlem Shake are interesting, some humorous, some leave you wondering "what were they thinking?".
