0 5 Points: Talk about unoriginal. You're going to spend way too much time this year making a costume of some lame, over-done character. Harry Potter? Are you serious? This is against my principles, but I'm going to give you some advice that is going to help salvage your idea. Pretend you haven't read the books and be dead Harry Potter. Take the idea you've been working on all week, add fake blood and maybe one of those arrow-through-the-head things and you've turned your lame costume hilarious. If you're a girl you'll pick a slutty looking movie heroine, probably Tomb raider.
6 10 Points: Be honest, are you a history professor? You're going to be some boring early-American hero like Paul Revere for Halloween. Your costume will be historically accurate right down to the last detail. No one else will know who you dressed up as. Be prepared for comments like "Neat, a pilgrim."
11 16 Points: Welcome to the world of topical Halloween costumes. Depending on your wit this could range anywhere from a recent internet phenomenon like Chris Crocker or Dramatic Chipmunk, to something clever like Facebook Application Zombie. There will be much more of the former walking around campus.
17 21 Points: Taping a toaster to your head doesn't mean you dressed up. The pledge working the door at the "No one admitted without a costume" basement frat gala might think it's awesome, but we all know you only dressed up to get drunk, cause trouble and sleep with the girl who got 0 6 points.
