Never trust Kyle Walker. Sure, he may be a hardworking fullback, a willing passer, and a good teammate on the pitch, but as the video above shows, he's not above freaking out his fellow players and capturing their reactions for all to see. Which we love him for, obviously.

SpursTV recruited Walker to help play a prank on a few Tottenham players. After being lured into a small room ostensibly to film a short clip about Halloween, the unsuspecting players are greeted by a roaring, masked Kyle. Andros Townsend probably comes off the worst, immediately crumpling to the floor. Jan Vertonghen though? Ice water in those veins.
