THE FIRE DOG英语笑话阅读

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 Dalmation dog.
The children started discussing what the dog's duties might be.
"They use him to keep crowds back," said one youngster.
"No," said another, "he's just for good luck."
A third child concluded. "No silly, they use the dogs to find the fire hydrant!"
