What DOES the fox say?

The latest internet sensation is a music video by Ylvis, a Norwegian comedy duo from Bergen. The duo consists of brothers Bård and Vegard Ylvisåker who debuted as professional variety artists in 2000. 
Their song "The Fox" became Viral in September of this year.
If you didn't listen to the words, you would think that it was a legitimate song on the music charts. 
The video is brilliantly produced and artistically played out, like many of the music videos that are so popular today.
Of course, when you listen to the song you realize that it's purpose is solely comic. The brothers sing about the different sounds animals make and then ask the question "what does the fox say?"
The end of the video displays a computer generated fox dancing and saying different things because, he's a fox of course. He wouldn't be a sly fox if he just let the world know what he said.
And really, what DOES the fox say?
