Picture the scene. I've invited you into my house on Halloween. You've been trick-or-treating. I have no candy to offer you, as it's all in my mouth. I blow some big bubbles with bubble gum and smoke a cigarette. But there's one thing you don't know about me: I'm actually a witch. You awaken to find yourself in my bedroom. I tell you that on the count of 3, I will turn you into a frog. I blow 3 bubbles, and then...bam. You're now a little frog, and I'm going to release you into my garden. Happy Halloween!
