Bård and Vegård Ylvisåker made the fake documentary about  Mikkel Eriksen, who is half of the Stargate Production duo behind hits for Rihanna and Beyoncė, for his 40^th birthday earlier this year. 

“In exchange we asked if they would help us create a song,” Vegård Ylvisåker told Norway’s VG newspaper. “We said it really just nonsense, but they said yes, for some strange reason. We were a little caught off guard.” 

In the video,  Vegård impersonates Eriksen,  who the narrator solemnly intones is known as "the bald wizard", and mocks his Norwegian-inflected English, particularly the way he pronounces the word 'cook' as 'cock'.

The Fox last week reached number six on the US billboard charts, the highest Norwegian entry since Take On Me by A-ha, which hit number one 28 years ago.
