What You'll Need: This one is pretty simple. Just strap a white board to yourself like a sandwich-board and make sure you have some erasable markers to keep changing those oh-so-witty slogans. "Half of all marriages end ... in sweatpants." (Groan.)

Optional Accessories: An arsenal of smug faces to make when people ask who/what you are; your own laughtrack for when no one laughs at the explanation.
