A grandfather was delivering his grandchildren to their home one day when a fire truck zoomed past.
Sitting in the front seat of the fire truck was a Dalmatian dog.
The children started discussing the dog’s duties.
“They use him to keep crowds back,” said one child.
“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 hydrants.”
