Advice Urgently Needed

[rainmaker]

I know this is going to sound like an open invitation for abuse and general insult, but it's a serious question and I hope you'll save the clever and humorous banter for later, after the problem is solved.

I am suddenly called upon to don a costume and stand in the doorway of a store handing out candy to trick-or-treaters. Of course, the ref stuff comes immediately to mind, but I'm wondering if there would be any little additions that might make it a little more costume-y or funny? I don't have time to do anything that involves much time or money. I've got a bright pink whistle, anytning I could add to that? suggestions?
