Sven and Olie died and went to Hell. After awhile, the Devil came by to see how his new guests were doing. To his amazement, he found Sven and Olie were still wearing their winter gear and seemed to be quite comfortable. The Devil asked why they weren't hot.
Olie replied, "We come from Minnesota where it's always cold. This is feeling pretty good to us." This upset the Devil, so he turned up the thermostat. Awhile later the Devil looked in again on Sven and Olie. To his surprise he found they were still wearing their winter gear. The Devil questioned them on it again. "You have to remember that we are from Minnesota and it's very, very cold there. This is feeling nice to us."
The Devil was even madder at this, so he turned the thermostat all the way up to maximum temperature. The Devil waited some time and then went back to Sven and Olie. This time he found they had only unzipped their coats, but still had all their winter clothes on. The Devil couldn't understand what was going on. The punishment down here was supposed to be the unbearable heat. It wasn't working on these two. He had to ask again what the deal was. Sven replied, "We are Minnesotans and we just got over a freezing winter. This is really great for Olie and Me.
A light flickered in the Devil's mind. He went to the thermostat and turned it off. He thought if the heat wasn't a punishment, maybe he'd give them some freezing temperatures. A little while later the Devil came back to check in on Sven and Olie only to find them cheering and giving each other high fives, happier than ever! The Devil questioned them on their actions and Sven said happily, "Back home they always said, the Vikings will win the Super Bowl when Hell freezes over!!!"
