The Vegas Golden Knights forward pulled off an amazing, between-the-legs move on a breakaway to beat San Jose Sharks goalie Martin Jones.
The ridiculous score ended up being the game-winner for the Golden Knights, which also clinched the Pacific Division with the victory.
Oh, it was also a shorthanded. Karlsson's second shortie in as many nights.
In the final home game of the Golden Knights regular season, the fans got one heck of a show, in true Vegas fashion.
