Dean Fisher’s sister ordered a Sidney Crosby jersey for her son, but later realised that she had accidentally ordered it in too small a size. Since there was no time to return it before Christmas, she decided to have some fun with her cousin’s son, a loyal Philadelphia Flyers fan.

The rivalry between the Flyers and the Pittsburgh Penguins is among the fiercest in hockey, and this reaction from the six-year-old fan when he opens the opposing jersey illustrates perfectly the enmity between the teams. Credit: YouTube/Dean Fisher
