Loki!
Loki: What is the best trick you've ever pulled on someone?
She giggles. "Ohh, boy. Ok, this is a good one. So about a year ago, I was over at a friend's house on study break, right? And her parents, they were pretty typical magic-isn't-real people. I dunno, super-religious folk, or whatever." She waves her hand. "Anyway. So I was telling my friend about this new potion that I'd been learning to brew over lunch, and I kept getting these scornful glances and disdainful mutters and whathaveyou from her parents. So then, after lunch..." She sniggers, devilish grin on her face. "My friend and I... we found a toad, in the back garden, and we m-managed to convince her parents - that s-she'd been - turned into a toad by accident!" She cackles loudly, close to tears. "Oh man, it was brilliant! She, like, hid behind the door and did this squeaky little voice - they completely fell for it!"
She pauses, wiping a tear from her eye. "'Course, I "changed her back" before too long. Wasn't invited to their house again, though."
