The 'Harlem Shake' is 2013's Gangnam Style, and everyone is getting in on it, including Lebron James.

The scene starts with the Birdman flapping around a bunch of Heat players stretching in the locker room.

Then the beat drops.

Bosh is holding a golden boombox, Wade is wearing a horse head and Lebron is dressed as that guy selling butter.  I thought only bad teams were supposed to do stuff like this, not defending champs.
