Video: This adorable young fan gets the surprise of a lifetime!

Liam Fitzgerald is a Bruins superfan, and he made national headlines earlier in the season when a video of him fist bumping members of the Bruins went viral. Liam has down syndrome and his interaction with the Bruins and how happy it made him struck a chord with fans and players alike. He's been somewhat of a mascot for the team ever since, and on Thursday the Boston Bruins and Upper Deck decided to reward him with something that every young fan dreams about. Liam was in attendance at TD Garden for the unveiling of his very own Upper Deck hockey card. You can see his excitement in the video below.
