UPDATE:

• SACRE BLUE!: "loser's point"
• "the greatest collapse in their franchise's eight-decade history"
• "only something out of ordinary, "supernatural" if you will, seems plausible"
• "the calamity is as simple as that"
• "At the moment I loathe the city of Montreal"
• "impossible to believe"
• "What the hell happened!?"
• "not to worry"
• "What the f**k?"
• "une équipe en mission"
• "Have you had someone build up something so much to be so great and then at the very last moment, take it all away from you?"
• "Ultimate Choke Job"

and, uhh, Maxim Lapierre scores Montreal's second goal. Poor Michael Ryder. First he loses his hat trick to Streit, now Newsday takes away another goal. Then again, it seems they left halfway through the second period.
