Luna: Hello Tom.
Voldemort: Who are you Luna girl? How do you know my name? How dare you speak it? I WILL DESTROY YOU, FOR I HAVE THE ELDER WAND!
Luna: I'm Luna Lovegood, and I'm in Ravenclaw. Oh, your profile picture just looks like a Tom. Also I think you have some marbles in your head.
Voldemort: How DARE you insult the Dark Lord!
Luna: Auto-correct, it's a funny technique. I meant Nargles, I see some in your profile picture.
Voldemort: Nargles?
