Ellen DeGeneres definitely knows what the fox says. The talk show host invited Norwegian band Ylvis onto her show Thursday (Sept. 19) to discuss their song "The Fox."

Never one to pass up an opportunity for fun, DeGeneres showed off her singing skills with the brothers by performing a bit from the viral hit. And -- surprise! -- she nailed every weird lyric in the song's catchy chorus. 

Following the funny performance, which had DeGeneres busting out some dance moves, you can even hear her say "oh my God, that was fun!"
