Escaped Midget Psychic

Hey, listen up, smarty pants. So, a midget psychic escaped from jail, right? Get it? A "small medium at large"? Because a psychic is sometimes called a "medium," and the midget is, well, small. Plus, "at large" means they're still out there, see? You probably think "at large" means something that's really big, huh? You probably play with toy cars, and then eat the toy cars. You're the reason why they make warning labels, aren't ya?
