The first NBPA Summer Camp is well underway at Baruch College in New York City and campers have been surprised by different NBA players each day of the camp.

On Wednesday, Detroit Pistons star Andre Drummond showed up to the camp to teach the campers a thing or two about basketball and life.
 

The 2016 NBA All-Star wasn’t the only special guest in attendance on Wednesday, though. Drummond was joined by actor Justin Bartha, best known for his role as 'Doug' in The Hangover trilogy, and the 39-year-old gave the Pistons centre a run for his money in a game of one-on-one.
 

It was a close call for Drummond, but the 6-foot-11 NBA star ended up coming out on top in the end.
