As a consolation, here is a GPOYW from a party a week and a half ago. The theme was movie/comic/videogame heroes. I went as Ash from Evil Dead and Candice went as Lara Croft from Tomb Raider. Best part of my costume? The chainsaw worked!* Also awesome was that my entire costume was under $50, half of which was buying the chainsaw. Half of the rest was buying the airsoft shotgun. The cut-up bomber jacket, two belts, corduroy pants and can of spray paint covered the rest.
*Worked as in it made noise and the ‘chain’ shook back and forth.
