Remember 'What Does The Fox Say'? It was that goofy song from the Norwegian comedy duo Ylvis. Well, the brothers are back with a funny look at those popular acapella groups like Pentatonix.

This parody is perfect, right down to the reference to the leather straps these groups always seem to wear, and what's with all the smiling? You enjoy this video, I'm off to the mall to grab one of those cool infinity scarves.
