lol..Sadly I've made one of those before. After watching Signs me and one of my friends went back to her house and made a few to wear around.

"Fairly Stern Warning to deadbeats:
No Non-Paying-Bidders please! If you back out, I will hunt you down and taunt you to within a centimeter of what the local laws allow.By asking for a refund you forfeit your ghost to me but it will be returned if you bake me a cake and hand deliver it."

This guy has way to much time on his hands though.
