There's been some fierce competition at a basketball game in the US - but not from the teams battling it out on the hardwood.
During the Detroit Pistons' clash with New York Knicks last week, a dance-off broke out between a young fan and an usher at the stadium – much to the delight of the crowd.
The video, which has had more than 2.5 million views on YouTube, shows the two dancers busting their best move before 'throwing it back' to the other for their turn.
Meanwhile on the court, Rodney Stuckey scored 15 of his 21 points in the second half to help the Pistons to their first win over the Knicks in eight meetings.
Carmelo Anthony was the Knicks' top goal-scorer with 25 points, but couldn't help get his side over the line; the Pistons claiming a 92-86 victory.
