The Fox was released in September 2013 by Ylvis, the Norwegian comedy duo of brothers Bård and Vegard Ylvisåker, as a joke single promoting the new season of their talk show. Uploaded to YouTube with a deadpan music video of animal costumes and forest choreography, it exploded into one of the platform's biggest viral hits, climbing the charts worldwide. The question at its center became a catchphrase, and the gibberish animal sounds turned into a lasting meme, still quoted in animal videos and reaction edits more than a decade later.
