Ylvis, made up of the Bård and Vegard Ylvisåker brethren, became an online superstar in September when they published a YouTube movie that inspired audiences around the world to wonder what a fox makes.

Both in the film and in last night's show they dressed up like chestnuts, singing and dancing together with a multitude of other creatures such as a steed, an bull and a seabird. Fallton and the soot even came on scene and put on their own fox outfits as they were joining the band on set.

The Fox (What Does the Fox Say?)" has over 100 million viewpoints on YouTube. On Friday the Brethren will take their fox uniforms to Rockefeller Plaza when they play their song on Today.
