I have never been one to not share -- but then we don't do very original costumes. We went to a costume party several years ago and the host would not share what he was going to be for Halloween. But when I saw him...it was so creative (and amusing...and topical) that I can understand the not sharing. He was Roy (or was it Siegfried?!) -- he had on a tuxedo with fake blood and attached a white tiger stuffed animal to the arm.
