A mom is driving her second-grade daughter and two of her friends to school one day when a fire truck zoomed past. Sitting in the front seat of the fire truck was a Dalmatian dog. The children started talking about what the dog's duties were.
One little girl said, "They use him to keep crowds back."
"No," said another, "he's just for good luck."
The daughter said, "No! No! They use the dogs to find the fire hydrants."
