The best feud on Twitter added another chapter on Sunday.

Brad Marchand and Torey Krug never have shied away from taking jabs at each other on social media, and Marchand just landed the latest blow.

The Bruins winger wanted to wish everyone on social media a happy St. Patrick’s Day, but just couldn’t keep himself from taking an easy shot at his teammate.

Krug could use some luck of the Irish, as the defenseman is dealing with a concussion that kept him out of Saturday’s tilt against the Columbus Blue Jackets.

But we can surely expect some retaliation from Krug once he’s feeling a bit better.
