WATCH: Questlove Answers the Musical Question “What Does the Fox Say?”

The drummer and Jimmy Fallon got furry with Ylvis.

In case the runaway viral smash “The Fox” by Norway’s Ylvis slipped under your radar until right now, or if you’ve always wondered “just what does a fox say?”, we present for your lazy Saturday viewing pleasure the duo’s stunning performance with The Roots on Late Night with Jimmy Fallon, featuring everyone’s favorite afro-pick’d drummer/band leader rocking it vulpine style.

If you’re wondering just who the heck Ylvis is, it’s actually brothers Bard and Vegard Ylvisaker, and they’re sort of like Norway’s Flight of the Conchords. They host a show called I Kveld Med Ylvis (Tonight With Ylvis) on TV Norge and they and their runaway hit just got the New York Times treatment:

This week, “The Fox” reached No. 6 on Billboard’s Hot 100 singles chart, surpassing hits like Robin Thicke’s “Blurred Lines” and Lady Gaga’s “Applause.” An equally mystifying video that features the photogenic Ylvisakers and other performers in a variety of animal outfits, evoking “I Am the Walrus,” if it had been directed by Lars von Trier, has been viewed more than 100 million times on YouTube.

Here’s the original video for “The Fox”:

And here are some of the group’s other weirdo videos, including this one about being obsessed with Stonehenge:
