well, I heard the version Loki was smart enough to tell that the wager is his head, not neck, so they're not supposed to cut it. Dwarfs weren't happy about that, but they agree and just saw his mouth. But Loki removed that in moment he was hungry.
the stories just based on the myth, but aren`t 100% a copy of it. So some things will be always a little bit different. I know that Loki tricked the dwarfs by not allowing to hurt his neck, wich made it impossible to cut his head off, but nevertheless his mouth became sewed up by the gods to avoid trouble with the dwarfs, which didn`t amused Loki very much...
da bekommt er diese blöden nähte raus und dann muss er
zum zahnarzt xDD
