Icelandic Parliament member Árni Johnsen nearly died in a car accident in 2010 but was saved by a family of elves living in a 30-ton boulder nearby. So, to thank them, he's agreed to move their boulder onto his property where they can live their lives in luxury and not off the side of a highway.
I had Ragnhildur Jónsdóttir, a specialist in the affairs of elves from Álfagarðurinn in Hellisgerði, Hafnarfjörður, to come look at the boulder with me [...] She said it was incredible, that she had never met three generations of elves in the same boulder before [...]
She said an elderly couple lives on the upper floor but a young couple with three children on the lower floor [...] But they asked whether the boulder could stand on grass. I said that was no problem but asked why they wanted grass. 'It's because they want to have sheep.'
Admittedly, I was gonna call bullshit on this one from the start, but with names like "Álfagarðurinn in Hellisgerði, Hafnarfjörður" -- I dunno, that sounds like a place where elves might actually exist. And if they do... "We should go there, catch them in a sack, then beat it with a stick till they teach us earth-magic?" Bingo.
Thanks to Ulri, who already has a family of elves living in the backyard but doesn't like to disturb them or they'll break in and steal things out of the kitchen cabinets.
