If looks could kill.
The Blue Jackets exploded for four goals in six-and-a-half minutes to start the third period Thursday against the Penguins, and Pittsburgh head coach Mike Sullivan's reaction to Columbus' seventh goal - Scott Hartnell's third of the night - was priceless:

As hats rained down on the ice, Sullivan kept his eyes peeled on the Blue Jackets bench, using a smile to try to get the attention of Columbus coach John Tortorella.
Hartnell's hat trick goal came just as a Blue Jackets power play expired, and Sullivan was apparently ticked off about Columbus' first power-play unit being on the ice in a 6-1 game.
According to the Blue Jackets broadcast, though, the Penguins did the same to Columbus last season, so it appears Tortorella was only returning the favor.
The game ended 7-1 Columbus, running the Blue Jackets' win streak to 11.
