There's a crisis in Norway, a butter crisis.
Butter is so scarce there, that it's selling for $20 a pound, four times its normal price.
People are desperate for butter because of Christmas cooking.
A new low-carb diet sweeping the country is partially to blame. The diet emphasizes high fat intake, and dieters have bought butter until the shelves are empty.
Sales of butter soared 30-percent last month.
Denmark, right across the channel, is a world exporter of butter, but high tariffs makes it too expensive to import into Norway.
