On October 12th in 2013, Vancouver Canucks defenseman Dan Hamhuis misplayed a breakout from behind his net, deflecting the puck off both of Roberto Luongo's skates and into the net for an own goal, giving the Montreal Canadiens a 2-1 lead with four minutes to play in the middle frame.
The bizarre miscue, coined by NHL goalie turned Hockey Night In Canada commentator Kelly Hrudey as "one of the strangest goals you'll ever see in hockey", was credited as a shorthanded goal for Canadiens' forward Lars Eller, the Dane's fifth marker in as many games.
Asked about the gaffe in the post-game interview, Luongo noted "I didn't see it, I don't know what happened". When asked if he had ever given up a more bizarre winning goal, Luongo made clear "I didn't give that up".
The Canadiens scored two more goals to beat the Canucks 4-1.
That's today in NHL history.
