Although it would help if you wore some proper fucking winter clothes.
But In The Original:
Frozen was inspired by Hans Christian Andersen's "The Snow Queen." The story opens when a demon creates a magical mirror that hides the beauty in whatever it reflects, while intensifying its nastiness. When said demon and his pals attempt to carry the mirror to heaven to troll some angels, they drop it and it shatters. Enter best friends Kay and Gerda. Similar to Anna getting struck by Elsa's powers, tiny shards of magic glass spear Kay in his eye and his heart. This has the side effect of transforming him into a Joffrey-caliber little dickhole, Which is pretty understandable, actually. Ever put a contact in backwards? Well, you try getting slivers of demon glass in your eye, you'd be grumpy, too.
Kay is then kidnapped by the Snow Queen, and Gerda sets off to find him. Along the way she, too, gets help from a reindeer and its owner. But this ain't hunky Kristoff and his wacky pal -- it's a psychotic little robber-girl who tells Gerda, "I tickle [the reindeer's] neck every evening with my sharp knife, which frightens him very much." Between the ice theme, the eye-stabbing, and the animal torture, we're not sure if this is the source material for Frozen, or the inspiration for the first season of Dexter.

We guess "Oh fuck, my eye! Jesus Christ, that hurts!" wasn't as catchy.
