Mullen, the Wenham ad agency, broke another ad for the Boston Bruins after the B's swept their arch rivals, the Montreal Canadiens -- a.k.a. the dastardly Habs.

The ad is the latest in a series of spots with the theme of "Bruins Hockey Rules."

The message of this spot: "Always have your victory dance ready."

An earlier ad in the series showed a Bruins buff committing the most grievous of hockey mortal sins -- dating a sightly Habs fan.

According to Mullen, ads from the campaign have already been viewed more than 500,000 times on YouTube.
