Lately, there’s been a whole lotta shakin’ goin’ on. The "Harlem Shake," that is, and it’s a dance that in-house counsel should be thinking about.

Versions of the "Harlem Shake" are being recorded in offices around the country and uploaded to the web. And it’s not only folks working in cubicles: LeBron James and the Miami Heat are doing it. Employees in NASA’s control room are doing it. Even bottles and cans of Pepsi, it seems, can’t resist getting in on the "Harlem Shake" action. The clips feature a now predictable sequence of first one, then a growing cast of costumed characters dancing to the song by Brooklyn deejay Baauer. There are thousands of the 30-second videos on YouTube, and some of them are causing unforeseen aftershocks in the workplace.
