... it's true. http://www.newsinenglish.no/2011/12/06/butter-shortage-keeps-spreading/ It's all over the news here in Denmark and a collection of butter is going on here, which will then be transported to Norway. Apperently people in Norway offer beers in exchange for butter so if you're going to Norway in the near future, bring butter!
This is not the first time Norway has run out of things. Years ago they ran out of toilet paper! It's true... http://www.dailytimes.com.pk/default.asp?page=story_10-5-2004_pg9_3 Again Denmark organised a collection of toilet paper which was transported to Norway. Don't think they got any beers in exchange though.
