Ylvis is made up of brothers Bård and Vegard Ylvisåker. Besides being talented musicians and pretty good dancers, the brothers have worked as comedians and talk-show hosts in their home country of Norway for many years. Their music video "The Fox (What Does the Fox Say?)" appeared on YouTube on September 3, 2013. Within a few months, it had become a global phenomenon, with more than 200 million views. Now, the brothers have taken their fun lyrics and have paired them with Svein Nyhus's playful illustrations for a whole new take on the fox's unique way of speaking. What Does the Fox Say? is Ylvis's first picture book. Learn more at Ylvis.com. Christian Løchstøer cowrote the lyrics of "The Fox (What Does the Fox Say?)" with Ylvis.
