My favorite Halloween costume is Toilet Paper Mummy, which is probably the least expensive get-up you can cobble together outside the ghost-bed sheet motif. All you do is wrap yourself up in toilet paper and duct tape yourself together. The TP mummy is always good for laughs at parties, and the costume only gets better as the night goes on, making you look more and more authentic as the paper tatters and drags behind you. [More]
