A primary 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 rather large Dalmatian dog.

The children started to discuss the dog's duties.

"I think they use him to keep crowds back," said one youngster.

"No way," said another, "I reckon he's just for good luck."

The third kid brought the argument to a close...

"They use the dog," she said firmly, "to find the fire hydrant."
