Claude Julien had a few words of advice for goalie Tuukka Rask after the final horn sounded Saturday night at TD Garden, officially sending the Boston Bruins off to the Eastern Conference Finals. "You can start laughing now," Julien said, repeating the words he told Rask. Talk about relief for Rask -- and one pretty darn comical memory from the conference semifinals against the New York Rangers. It was Rask's gaffe in the second period of Game 4 that gave the Rangers momentum and the belief that maybe, just maybe they could do the same thing to Boston that the Philadelphia Flyers did four years ago -- win four straight games after losing the first three. Rask fell on his rear end -- "Butt Stumble" is what they're calling in it Boston, a play off the "Butt Fumble" from the New York Jets-New England Patriots game last fall -- and Carl Hagelin's wonky, wobbling, deflected backhanded shot went trickling past him to bring the Rangers within 2-1 at 8:39 of the second period Thursday night. The Rangers found their legs and some life after that goal and went on to win the game 4-3 in overtime to send the series back to Boston on Saturday. But Rask got, ahem, the last laugh, with 28 saves in a 3-1 series-clinching victory at TD Garden. His best stop came on Ryan Callahan's breakaway with 8:38 left in the game and Boston hanging on to a 2-1 lead.
