Put a Ghost on It

I recently sat in on a meeting of a group of pre-K through second grade teachers planning their school's Halloween celebration.They were charged with coming up with Halloween games for the event. One of the teachers provided the succint suggestion: " Take a traditional game, like bowling or bean bag toss, and put a ghost on it." This seemed to me to be a wise, efficient, and sufficiently scary recommendation for a holiday that calls for just the right balance between terror and delight.
