By far, one of my favorites was watching Fleury in the pre-Winter Classic shootout. (Starts around 0:50 of the video).
By the time he said "I have quick legs! Unforgettable!" I was dying of laughter. Even if you're not a Pens fan, you have to admit, it is hilarious.
And it was even more hilarious when a few minutes later I remembered this commercial, also featuring a cocky goalie with a French accent.
I wish Fleury had yelled "Sensationale!" but I guess watching him yell "fuck face" is also pretty great. I kind of love him now.
