Dirk Nowitzki gets a little too excited after an alley-oop dunk by one of his teammates.

It appears that Dirk Nowitzki has not been able to shake off the hangover from the Dallas Mavericks’ 2011 championship party because the way he reacted after an alley-oop dunk by teammate Brandan Wright against the Minnesota Timberwolves on Jan. 25, Dirk sounded like a college student partying at Oktoberfest.

On a night when the Mavericks got their 2011 championship rings, Nowitzki was helping with TV commentary when Jason Terry picked up a loose ball and dished it off to Wright for a spectacular slam. That play not only got Dirk off his seat, but he started screaming “Shut it down! … Let’s go home!” His teammates were probably listening because the Mavericks did shut it down, and the Timberwolves went on to spoil the Dallas party with a 105-90 victory.
