Ylvis. That's the Norwegian duo made up of brothers Bard and Vegard Ylvisaker and in their home country they have the top rated television show, the number one selling album and their concerts sell out night after night! Oh, and did I mention? They're just plain strange.

This video is Ylvis' latest hit single, 'The Fox'. It was released about a month ago and already has more than 40 million views on YouTube. And it is, without a doubt, the weirdest music video ever. But, like I said, once you start watching...you cannot turn it off!
