One day a police officer managed to get some fresh mushrooms.He was so pleased with what he had bought that he offered to share them with his brother officers.When their breakfast arrived the next morning,each officer found some mushrooms on his plate.
“Let the dog try a piece first,” suggested one careful officer who was afraid that the mushrooms might be poisonous.The dog seemed to enjoy his mushrooms,and the officers then began to eat their meal saying that the mushrooms had a very strange but quite pleasant taste.
An hour later,however,they were all frightened when the gardener rushed in and said the dog was dead.Immediately,the officers jumped into their cars and rushed into the nearest hospital.Pumps were used and the officers had a very hard time getting rid of the mushrooms that remained in their stomachs.When they returned to the police station,they sat down and started to discuss the mushroom.Each man explained the pains that he had felt and they agreed that these had grown worse on their way to the hospital.The gardener was called in to tell the way in which the poor dog had died.“Look!Here!It was killed the moment a car hit it.”
