Ole and Knut are solid friends with the artist and great pretender, Georges Bête.
They all live in Paris.
Ole and Knut are always seen rushing about together, tremendously focused on some errand, work or indistinct purpose. Their full Viking garb is their everyday wear, but on rare occasions they will attend certain events "dressed down" but with a noticeable modern Viking flair. They are recognized all over the city, and known to each and every one who lives their neighborhood as being good guys.
Neither of them have actually been to Norway.
They just like it.
