For many people, sports fandom is almost like a religion. When Boston native and hockey fan Mark Karolkiewicz saw that Coca-Cola, Shaw's Supermarkets, and the Boston Bruins had teamed up to make one lucky Bruins fan's dream come true, he entered the contest right away—and then kind of forgot about it.

"And then, a month or two later, I get an email and it's from Coke saying 'Congratulations!'," Mark told us. Because he had purchased a Coke from Shaw's in the New England area, Mark won a "Player for a Day Experience" with the Boston Bruins, an incredible offer for someone who had been a Bruins fan his whole life. So how did Mark celebrate his wish coming true? He decided to give the prize away, to his son, Eric.

Eric Karolkiewicz, also a die-hard Bruins fan (thanks to his dad), said: "This is something I've always dreamed about doing—being a Bruin. And it actually came true for a day!"

As part of the prize package, Eric signed a one day contract with the Bruins, got a personalized team jersey, and got to visit a team practice. Eric, his father, and two guests also received a private tour of TD Garden, had a meet and greet with Bruins Assistant coach Jay Pandolfo, got to sit on the bench during the pre-game warm-ups, and received 4 prime rink-side tickets to a game! Eric described the day as "an unbelievable experience," and it was all thanks to his dad's generosity.

These two Bruins fans got an opportunity of a lifetime, out of the blue! Even more importantly, they got to spend an amazing day together: father and son enjoying a wish come true.
