Okay, send in those spreadsheets tonight and tomorrow! I'll have results early next week.
If you've never done this before, just send in an e-mail/spreadsheet/napkin with the following information:
--costume character (as best you can determine)
--quantity
My favorite, from several years ago, is still the little girl whose costume I couldn't identify. I asked and she said--proudly--"I'm Paris, France."
