Kanye West tries out for the final season of Fox's American Idol XV

The new advertisement pays tribute to the Fox show's joke contestants.

Kanye West has joined Sanjaya and William Hung in a new American Idol commercial celebrating what was once a big selling point of the show: the joke contestants. 

'American Idol' Will Bring Back Every Original Judge for Final Season, Ryan Seacrest Says

The new commercial looks back once more as Hung tells then judges Simon Cowell, Paula Abdul and Randy Jackson that he had "no professional training" -- with Cowell responding, "Noooooo."

Other Cowell-isms ("I think you're amazing ... amazingly dreadful") are relived to the beat of Kelly Clarkson's "Stronger (What Doesn't Kill You") until West walks in the door -- much to current judge Jennifer Lopez's surprise.

"What are you doing here?" she asks, before the spot cuts away.

The farewell season of American Idol debuts Jan. 6. Watch the new promo below.
