It's part of this parody comic book:
Blått Blod/Blue Blood in which Crown Prince Haakon, with the aid of a time machine, gets to meet his alter ego, Johnny from Stovner. It's not a very good book, in my opinion, not as a parody, a comic book or a book about royalty. Se & Hør's caricatures of the royal family have more point to them than this.
