Referee Wes McCauley returned to NHL Hat Trick Trivia, hosted by New Jersey Devils defenseman P.K. Subban.

Instead of his usual rules of the game, McCauley changed things up and quizzed Alberta’s Rob and Charlie Parrotta on the signals of the game.

Typically, fans answer three questions to win prizes.  In the signals quiz, Rob had 60 seconds to get as many right as he could.  Two correct would earn him an NHL hat, four for a jersey, and seven for a hat, jersey, and two tickets to a regular season NHL game.  Check out the video and see how you fare!
