It's not every day a music video leaves everybody wondering what the hell they just saw. Congratulations, Ylvis -- you just made the entire world scratch their heads in unison!

In arguably what is the most bizarre music video of all time, Ylvis, made up of brothers Bard and Vegard Ylvisaker from Norway, dance in a trippy jungle rave and cavort with people dressed in animal costumes. But the part that has everyone talking is the crazy animal noises that the band sings during the song's chorus.

Following the song's question 'what does the fox say,' the brothers scream out several strange phrases. While we admittedly don't know how foxes sound in Norway, we can say with certainty that in the US they don't say "fraka-kaka-kaka-kaka-kow" or "A-hee-ahee ha-hee."

This is the song and video you and all your friends will be talking about for the foreseeable future. It's just too weird not to be.
