Dirk Nowitzki did some holiday good last week at Children’s Hospital in Dallas. The 7ft-tall Mav passed out some awesome presents to kids spending the holidays at Dallas Children’s Medical Center.

Everything was going great and then Dirk met Will Kolassa. The 4ft-tall Chicago Bulls fan went toe-to-toe against Dirk in a game of hospital hoops, and Dirk got schooled.

Will’s first shot was a fade-away jumper right over Dirk’s head. Dirk came back with a dunk or two, but in the end Will proved that he plays a pretty mean game.

Dirk succeeded in making a fan out of Will, and you can watch the epic battle above.
