the most outrageous, eccentric stories come out of the mouths of munchkins who simply do not want to go to bed, whether there is a monster under the bed, they have to pee or require a drink of water.
Mind you, they only need a drink of water when they are supposed to go to bed. Any other time of the day they need Juicy Juice, orange juice, lemonade or, when they really think they can get away with it, just a little glass of pop. Forget the water, baby, except at bedtime. And when they have to pee during normal waking hours they walk around all bunched up, grabbing and generally carrying on like they are inventing a new danged dance. At bedtime they civilly just have to pee.
