Most unusual: I have a Kyle Wellwood jersey (the old 3rd - still one of my favourite designs), and my dad has Maple Leafs nutcrackers (one home, one away) that his brother gave him for Christmas one year.
Coolest: Darcy Tucker handed me a warm-up puck at my first ever regular season NHL game in Montreal (got a fist-bump from Shayne Corson (who I was actually named after) after that same warm-up, as well), and Dougie Gilmour responded to a letter of mine when I was a kid with a package that included an autographed picture of himself, a 94/95 team photo, a letter, and an 'IBELEAF' sticker.
