The reigning champions can't just sit around while the Mavericks and Raptors get their shake on. So they did what champions do, they put up the best Harlem Shake video on all of YouTube to end all competition. Shout out to Mario Chalmers for bringing back a dance move I haven't seen since 2005, and for that Mario costume.
The NBA on TNT crew joined in on the fun later in the day. This is what happens when Ernie is not in the studio.
