Casper Ruud serenaded with improv song by Ylvis on Norwegian talk show

WATCH: Ruud has attracted his share of attention from the music world this fall: Jin from BTS watched his opener in Seoul.

We may never know what the fox says. But in the meantime, the geniuses behind Ylvis have blessed us with yet another utterly inconceivable bop—this time dedicated to our very own Casper Ruud.

The Norwegian comedy duo, who went viral in 2013 thanks to The Fox {What Does The Fox Say?} were booked alongside Ruud on Kåss Til Kvelds—or Sausage for Dinner, per Google Translate—and were challenged to improv a two-minute song in honor of the two-time major finalist.

The result is better shown than told.

Ruud has already gotten plenty of attention from the music world this fall with Jin from BTS stopping by to watch his match in Seoul, and gave Ylvis’ performance rave reviews on his Instagram.

“Already stuck in my head,” wrote the former world No. 2, who is now a national hero after becoming the highest-ranked Norwegian in tennis history.

Ruud’s victory lap has continued on social media as he hypes a Buenos Aires exhibition with French Open champion Rafael Nadal and shouts out Stefanos Tsitsipas when a throwback video surfaced online.

The 23-year-old hopefully nabbed the .mp3 before heading to Basel, where he is set to play former world No. 3 Stan Wawrinka in the first round of the Swiss Indoors.
