Purpose of the Dog

      A Sunday School helper was delivering a station wagon¹ full of kids home one day when a fire truck zoomed² past. Sitting in the front seat of the fire truck was a Dalmatian dog. The children began discussing the dog's duties.
      
      "They use him to keep crowds back," said one youngster.
      
      "No," said another, "he's just for good luck."
      
      A third child brought the argument to a close. "They use the dogs," she said firmly, "to find the fire hydrant."
