Not so long ago lived a small boy who was very happy
Until one night he was driving along in a car with his parents and was going to a party, the car collided with a pin carrying truck that was driving on the wrong side of the road. The boys head was knocked off by a pin and the pin stuck into the place where the boys head should have been. The driver of the truck was never caught and all the boys doctors were very baffled until the boy said his brain was in in his trousers. He grew up being called a ‘pinhead' and was very upset.

When he left home he became a politician and made a campaign against trucks, his job was going very well and he became famous.

 
One day a man working for him found an old photo of the man and realised the guy had a pin for a head. The rumour spread and no-one would work for him.
He was suddenly chased by all the nearest grannies who wanted him for their notice boards; they chased him from his work building and down the street to a hill and the man ran up the hill and into a shed at the top of it.
He was hiding when he saw the truck driver who had made him into a pinhead,
They got into a fight and the truck driver threw a box of pins at him.
This made the man entirely into a pin and the grannies got in and used him on their notice board.
 
Moral: Don't call someone a ‘pinhead'
            They might just become one.
