NBA Hall of Famer Karl Malone went undercover as a janitor in an elaborate prank staged by Red Bull, with New Orleans Pelicans All-Star center Anthony Davis as the unsuspecting victim.
The setup: Davis arrives at a local gym for a basketball video shoot, which kept getting disrupted by "Sam the Maintenance Man".
As the "Mailman" dropped hints left and right, Davis had no idea what was going on, until Malone asked him for an autograph.
