The single Kjendisparty - Celebrity party - by Jaa9 (Johnny Engdal Silseth) and OnklP (Pål Tøyen) has been a Norwegian hit for independent label C + C Records, run by the first winner of the Norwegian version of reality show "Survivor", Christer Falck.

The single also attracted media attention due to its video being censored in the UK because Falck appears and gives the finger to the camera.

Falck confirmed Wednesday that the sale of the single had been stopped, and also revealed a few other quirky conditions of his contract with the Lillehammer rappers.

If their album sells 10,000 copies Falck is obliged to wash Jaa9's mother's house, wearing only tennis socks.

"There are many ways to wear tennis socks and I am used to housecleaning, so this will go fine," Falck told NRK. Falck said that his company is so small that he lets artists design dream contracts. Each of the rappers reportedly has asked for a hockey bag "full of Falck's porn".

The rappers, who also have an agreement not to be contacted by the media until after noon, said that they did not want the sale of their single to damage their album sales, and decided to hobble the single to make sure this didn't happen.
