Forget Boston Bruins-Montreal Canadiens. The biggest hockey rivalry in Boston is Brad Marchand vs. Torey Krug.

"But wait," you ask, "aren't Marchand and Krug teammates?"

Yes, but in the hockey universe, that's license for the two to give each other endless grief on the internet.

Case in point: A few hours after the Bruins' 4-3 overtime win over the Carolina Hurricanes on Tuesday night, Marchand came out of nowhere to chide Krug about his height.

But Krug didn't take Marchand's jab sitting down. Instead, the Bruins defenseman fired back Wednesday morning with a burn of his own:

Marchand took a while to respond Wednesday, but he didn't disappoint. 

We have some questions here... Is the label in Krug's tweet Photoshopped? If not, how much time did Krug spend on creating it? Did he actually go find a label-maker, come up with all of these witty lines and paste them on a pill bottle just to get back at Marchand?

Given their history, we wouldn't be surprised by the latter. Take this back-and-forth from early January:

Or this exchange from a month ago:

OK, one more:

And that's just from the last two months.

Long live the Krug vs. Marchand Twitter rivalry, which clearly isn't affecting either player on the ice: Krug is on pace for a career high in assists with 40 through 55 games, while Marchand leads the Bruins with 77 points (27 goals, 50 assists) as they ride a 17-game point streak into Wednesday's tilt with the Florida Panthers.
