Headcanon that even in the twenty-first century, Maglor still makes untranslatable Quenya jokes
“What do you get when you fish with a teakettle?”
“Hamsters.”
… and he just laughs as everyone else stares blankly at him.
Just imagine if he’s finally been dragged into Gondor because no one has any idea who he is, and he’s annoying the guards by making all these horrible jokes when Aragorn walks past and just cracks up. Because Elrond had used to tell that joke all the time and explained the Quenya behind it, and he remembers it.
So there’s these two poor guards staring in confusion between this ages-old elf, who is cracking up so much he’s almost crying, and King Elessar, crown and all, who is just lying on the ground laughing into the floor.
