The teachers at my DS10's elementary school dress up as characters for Halloween. One year, the kindergarten teacher was the old lady who swallowed a fly. She wore a gray wig, and had Beanie Baby animals from the song pinned to her clothing. Last year, all of the teachers were "Cloudy with a Chance of Meatballs"....they carried umbrellas which were decorated with pictures of food, and had meatballs (crumbled brown tissue paper) and clouds (fluffs of batting) hanging from the spines of the umbrella. Of course, one year everyone was the Cat in the Hat. I can't think of anymore...
