A little over a minute into last night's Canucks-Sharks game, the puck bounced off the boards on a Joe Thornton dump, rolled up the net, and knocked off Roberto Luongo's shoulder for a goal. It was an ugly moment for Luongo, who could have easily made the save with more strategic water bottle positioning.
The closest non-hockey equivalent I can think of in terms of sheer luck, weird physics, and lack of intention is the "saving-it-from-going-out-of-bounds three," but even that shot has happened a few times in recent memory. This seems to be a whole new thing.
