A nursery school teacher was delivering a station wagon full of kids home one day when a fire truck zoomed past.
Sitting in the front seat of the fire truck was a Dalmatian dog.
The children fell to 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.
She said firmly, "They use the dog's to find the fire hydrant."
