Vampires: I believe that they exist, but it's not proven. With
vampires, it's really a matter of belief. People claim to be
vampires, but if I were you, I wouldn't trust everything people
tell me.
Witches: Yes, but not the ones with green skin, flying
broomsticks and disgusting potions in a black cauldron. Yes,
sometimes we make potions, and yes, sometimes they're in a black
cauldron. But we rarely mix things that would win a smelliness
contest against a Boys' Locker Room.
