The song was really only supposed to be a promo or commercial to promote Ylvis' talk show "I kveld med YLVIS" on TVNorge, which in English means Tonight with YLVIS.
The group was shocked by the international success of what the fox say. According to the comedy group, supposed to entertain their small Norwegian audience for a few minutes. This is hilarious, I can't make this stuff up!
It was meant to be a parody making fun of how ridiculous techno club music is and you can make a song out of anything, kind of like Weird Al or Saturday Night Live in the US.
