The Bruins had gone more than two months without a gut-busting laugher. On Jan. 5, they booted the Flames out of TD Garden nursing a 9-0 beating.

On Monday at the Garden, another Canadian club finally felt the Bruins’ wrath. The Bruins laid an 8-0 thrashing on the Maple Leafs to cap a six-game season sweep of their division rivals.

The ferocity of the beatdown was captured in a second-period fight between old combatants Milan Lucic and Mike Komisarek. After trading jousts along the boards, Lucic and Komisarek - they had tangled repeatedly when the defenseman was in Montreal - shed the gloves. Lucic ravaged Komisarek with several ringing uppercuts to send the following message: goodbye and good riddance.

“It seems like so long ago,’’ Lucic said of his previous scraps with Komisarek. “He’s a guy who’s definitely going to compete. He’s just trying to show some emotion at a time like that. You don’t ever like to be on the other end of things. Whatever happened, happened there. Fortunately for me, I came out on top.’’

Benoit Pouliot scored twice. Brian Rolston (goal, three assists) led the Bruins with four points. Nobody had more than 21:50 of ice time (Johnny Boychuk was the leader). Tim Thomas laughed off a mere 13 shots to notch his fifth shutout of 2011-12.

“I have to be ready for whatever, so I wasn’t even thinking about the workload side,’’ said Thomas, who should get at least one breather during the upcoming road trip. “I started to feel better against Philadelphia. I think you could see it in my play. I felt good in practice this morning. I just wanted to carry it over, no matter what kind of shots I had. With the way the team played tonight in front of me and being able to get away with a zero will help me continue moving forward.’’
