Spurs center and future Hall of Famer Tim Duncan is widely perceived as a quiet, modest person who avoids the limelight and eschews flamboyance in his style of play. Hence his nickname, “The Big Fundamental.”

Contrarily, Duncan reportedly loves pulling practical jokes on his friends, teammates and Spurs head coach Gregg Popovich.

During Saturday night’s Spurs-Raptors game in San Antonio, Duncan showed fans his prankster side. Watch as Duncan pranks former teammate and Spurs TV analyst Sean Elliott on live TV during the pre-game warm-ups.
