(NEW YORK) -- Their video, "The Fox (What Does The Fox Say)," has nearly 300 million views -- and because of it, Norwegian brothers Vegard and Bard Ylvisaker have become an international sensation.
They were already famous in their homeland because they have a popular comedy show, but now the brothers, who call themselves Ylvis, have become authors, thanks to that song.
While it might seem strange to take such an odd song and turn it into a page-turner, that was always the goal.
Vergard tells ABC News Radio: "This was actually part of the plan, to be like a well-produced merchandise for a project that tanked...but at the same time when we started working on the book we thought that...the premise and the book and the story is well suited for a children's book, so, uh, we just continued and make it the book we planned to do."
The book, titled What Does the Fox Say?, is now available.
