It's the tooth fairy. Yep, he'd do it. He always answers people's wishes. And after everyone's given up on their governments more eager to spy on their people than tackle crime, surely got to be Tooth Fairy. But well, Tooth Fairies dont really exist, do they? Well then, it's Santa. It's a Christmas present. Santa's known to do it. Bring gifts unknown to us every winter. But then why would Santa be a non-state actor? There's no evidence he's done that before. Well, it's No-man from the Odyssey. Anonymous No-men, are known to poke the eyes of Cyclops. But then, no tales of no-men have emerged since a thousand years, and who is anonymous anyway? Enter the physicists: it's a combination of all these. All improbabilities that are probable, have probably occurred and there's every probability, they coexist, improbably. Well then that's it. There's no way of knowing who did it, but all we can say, Schadenfreude, dear Leader, it all goes in circles anyways.
