it's where you wanna get snowed in when you get snowed in

Theory:

When God was working on the Upper Midwest, He set the thermostat before He got to work on the landscape. And it was very cold. So God picked up a bit of a bug that was going around, but kept working because He's pretty industrious, and while at work He sneezed. But - because who's going to call out God for this? - He did not stifle, or cover His divine nose or anything like that.

And that is why there are ten thousand lakes in Minnesota.
