Altogether, 13 guests are expected at the little girl's party, and this is nothing but a cutesy-coy list of what each will be fed. Mother, who's plump and dumb-looking, will get diet soda, carrots, and celery, and the old tattletale next door is slated for grape juice to spill on her frilly pink dress. For her doctor, this vindictive child plans buckets of liver, eggplant, and paregoric--via a ""shot needle"" if he doesn't clean his plate; and for the dentist, cotton balls, rubber tubes, and mouth wash: ""I'll put everything in his mouth at once and then ask him lots of snurky questions."" Sister Shannon fares better with health foods, and brother Scott with his likely choice of kiddy snacks. Williams' final little twist has fond Grandpa arrive for a real visit, at which he and the little girl will ""very s-l-o-w-l-y"" share a package of lemon drops--whatever that indicates about his needs and/or deserts. For Williams' audience, empty calories.
