Just as we had finally prised Psy's 'Gangnam Style' out of heads along comes another irritatingly catchy and just as ridiculous novelty hit (complete with a new dance craze, natch) to take up residence inside our skulls.
'The Fox (What Does the Fox Say?)' by Ylvis has already notched up over 100 million YouTube hits and is currently riding high in the US Hot 100 Billboard singles chart.
Next stop: Great Britain.
'The Fox (What Does The Fox Say?)' asks that really important question that keeps us all awake at night: What noise does a fox make?
"Dog goes woof, cat goes miaow, bird goes tweet and mouse goes squeak. But there’s one sound that no one knows… what does the fox say?" go the lyrics.
So what does the fox say? Well, you'll have to watch the video above to find out, but be prepared to have the tune in your head for the remainder of the day, or possibly into the new year.
Don't say we didn't warn you.
