What Is Your Cheap Halloween Costume Idea?

I thought for sure that I had dodged a bullet this year, but it turns out that one of my best friends is hosting a Halloween party where we have to dress up. It's too late to order something online and I can't fathom going to a store and paying $60 for something I will never use again. A few years ago a friend and I went dressed as Paula Dean and a stick of butter, I thought it was genius up until we didn't win the costume contest. I am fresh out of ideas and have no idea what to do this year. If you are the creative one in your group chances are, a few people have already called you asking for a costume idea. Have you ever pulled off a genius or hilarious Halloween costume that cost you little to nothing? We want to try out your homemade Halloween costumes.
