Norwegian brothers Vegard and Bård Ylvisåker—better known as Ylvis—went viral in 2013 with their hit single “The Fox (What Does the Fox Say?), ” which finally asked the vulpine question on everyone’s mind (and resulted in a book deal). You might think of Ylvis as a one-hit wonder, but they’ve been busy hosting a variety show on TV Norge and making silly music videos, the latest of which is a pitch-perfect spoof of self-serious a cappella groups like Pentatonix.
In this video, Ylvis and friends set out to rescue a bullying victim using only their voices and beatific facial expressions. In trademark Ylvis style, this video pays close attention to detail (note the quintet’s coordinated woolen hats) and features plenty of non-sequitur punchlines (we finally learn why a cappella groups have been singing “boodelooap” all this time). Purists will note that this is not strictly a cappella—the track seems to have gotten some electronic help post production—but that’s not really the point.
