Video: John Wall vs. a fan in a 'Dougie' dance-off

John Wall is the preeminent NBA 'Dougie' dance-off expert.  Back in January, Wall had an impromptu dance competition with hip hop superstar Chris Brown in a club.  Wall is back at it.

At the Reebok launch party of his new signature snearker, the Washington Wizards point guard got into it with a fan.  At the same event, Wall told IamaGM's Shaina Auxilly that he was planning on entering the NBA All-Star Dunk Contest at some point over the next year or two.
