Dirk Nowitzki's just the best.
With 36.1 seconds left in regulation in Thursday's game between the Kings and Mavericks, the officials needed to review a play. As is NBA procedure during a review, players aren't allowed to interact with officials or influence anything. So there's typically a security official or a police officer to make sure players keep their distance.
Dirk, being Dirk, decided to have a little fun with that.
Pretty good defense by the security guy too. Look for Geoff Petrie to sign him to a 10-day contract in the next week or so.
