Two Canadians die and end up in Hell. Satan decides to pay them a visit, so he walks into their room and sees them talking and laughing. Confused, he asks them why they're happy.
They tell him, "Well, we're so sick of the cold where we're from, and this place is nice and toasty."
Satan, annoyed, storms away and goes to Hell's boiler room, where he turns up the temperature.
He goes back to the Canadians' room, along the way being begged by all sorts of people to put the heating back down. He enters the room to see the Canadians having a barbecue. Furiously, he asks them what they're doing.
"Well, we can't pass up this wonderful weather without getting out the barbecue!"
Satan realizes he's been doing the wrong thing. He goes to the boiler room and turns it down until it's at a colder temperature than ever seen on earth.
He knows he's won now, so he goes back to the Canadians' room, only to see them jumping up and down in excitement. He shouts at them in fury, "WHY ARE YOU STILL HAPPY?!?!?!"
They look at him and shout at the same time, "Hell froze over! That means the Leafs won!"
