I noticed this in a gif someone made from Adventure Time. The cup has runes on it, which (sort-of) say in modern English “Cup of many ale.” They’ve made an error in “cup,” however, and that last rune is either a thorn or a wynn (I can’t really tell), so technically what it says is either “cuth of many ale” or “cuw of many ale” — but I’m just happy to see it there at all!
