I think all the fans know who really jinxed the Habs

It looks like Trudeau's going to have to pay up. Earlier this week, the prime minister challenged the U.S. president to a bet Monday as the Montreal Canadiens squared off against the Tampa Bay Lightning in the Stanley Cup final.

"Two of the best teams in the NHL are facing off right now; how about a friendly wager?" Trudeau asked the commander-in-chief over Twitter, adding the hashtag GoHabsGo.

Biden replied three minutes later: "You're on pal. .GoBolts."

This isn't the first time world leaders have placed sports bets. For example, Patrick Brazeau, an indigenous senator from Quebec, responded to Biden's reply with a tweet addressed to the president. "The last time he offered me a 'friendly wager,' I lost and he snipped my hair. .GoHabsGo," Brazeau said of Trudeau, posting a photo of the haircut. Brazeau was referring to the charity boxing match he undertook with Trudeau back in 2012, which Trudeau ultimately won.

Pointing out that hair has a cultural significance for First Nations peoples, Trudeau said, 'I know, that's why I proposed it: When a warrior cuts his hair, it's a sign of shame, so it's very apropos."'

In 2014, president Barack Obama ended up owing former prime minister Stephen Harper two cases of beer when the Canadian women's and men's hockey teams triumphed over their American counterparts. In 1998, the Washington Capitals' victory over the Ottawa Senators in the Eastern Conference semifinals in 1999 forced the hand of prime minister Jean Chretien, who was made to wear a Capitals jersey presented to him by the U.S. president at the time, Bill Clinton.

So what humiliating task will Trudeau have to perform for Biden? We're waiting with anticipation!
