The bear returns, but wants your input, in this new installment from Mullen's Bruins Hockey Rules effort. The campaign's ursine enforcer puts his paw down, again, in the latest spot, but this time, viewers are asked to come up with the rule that drives him. Fans can upload their ideas at the Bruins Hockey Rules site and winners earn a chance to have their rule shown during a Bruins Game, a ride on the Zamboni and other prizes.
