The Norwegian brothers who answered the longing question, “What does the fox say?” and attempted to explain “Stonehenge” are back with a new trancing music video that takes on the a cappella craze that’s still storming the nation (see: Pitch Perfect and its sequel, The Sing-Off, Pentatonix). In it, Vegard and Bård Ylvisåker are members of an a capella group whose apparent sole mission is to stave off bullies by making pit stops along their tour route at schools where children need a helping hand, er, voice. This latest viral parody by Ylvis includes the tried-and-true ingredients they’ve used before: it’s very silly while simultaneously wanting to be somewhat serious as it makes fun of a cappella tropes and takes down bullies in the most non-violent manner possible. Oh, and no surprise here–the song happens to be extremely catchy so I’ll save you a step in finding the tune for keeps. Catch a funny behind-the-scenes look after the break.

Boodelooap!
