Susej Dog is the old testement spelling of 'Sausage Dog'. The great and all might Sausage Dog is the true creator. He is the only real diety, and quite a lazy one at that. Quite long too.
Texts written about him have been mistranslated backwards, to form 'Jesus' and 'God', which have apparently been adapted into a couple of manmade religions.
Tyler: "If you could fight one diety, who would it be?"
Narrator: "Sausage Dog."
Tyler: "Good answer."
