At the beginning of the Adventure Time episode Card Wars we can see Finn drinking from a wooden mug with runic inscriptions:
I've tried my best to figure out what those runes are, and my googling headed me to Wikipedia (Adventure Time Wikia doesn't mention the mug nor the runes).
In order of appearance in the mug I've identified the runes below:
Which seems to be some Elder Futhark runes. But even if I can identify some runes, the meaning is a mistery for me.
Does anyone know what the meaning of the inscriptions is and from where Finn got this mug?
