So, Farmer John called the local police station to complain, "You've got to do something about all these people driving so fast and killing all my chickens," he said to the local police officer.
"What do you want me to do?" asked the policeman.
"I don't care, just do something about those crazy drivers!"
So the next day the policeman had the Council erect a sign that said:
Three days later Farmer John called the policeman and said, "You've still got to do something about these drivers. The ‘school crossing' sign seems to make them go even faster!"
So again, they put up a new sign:
That really sped them up. So Farmer John called and said, "Your signs are no good. Can I put up my own sign?"
In order to get Farmer John off his back said "Sure. Put up your own sign.
The phone calls to the Police Station stopped, but curiosity got the better of the Officer, so he called Farmer John, “How’s the problem with the speeding drivers. Did you put up your sign?"
"Oh, I sure did and not one chicken has been killed.
The policeman was really curious and thought he'd better go out and take a look at the sign. He also thought the sign might be something the Police could use elsewhere, to slow drivers down.
So he drove out to Farmer John's house.
His jaw dropped the moment he saw the sign.
