Dalmatian

A nursery school teacher was delivering a station wagon full of kids home one day when a fire engine with lights flashing and a wailing siren at full blast zoomed past. Sitting in the front seat next to the driver of the fire engine was a Dalmatian. The children, never having seen a dog in a fire engine before, started to discuss what the dog might be for.

"They use him to keep crowds back," said one youngster.

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

Several more ideas were put forward and an animated discussion soon ensued when a little girl who had sat quietly throughout the discussion and deep in thought finally brought the argument to a close...

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