English KS1/KS2: Aesop's Fables - 40. The Boy who cried 'Wolf!'
A boy has the job of protecting a flock of sheep from wolves. If a wolf comes he is to ring a bell and cry out 'Wolf!' to rouse the villagers. After a few days with no wolf the boy is getting bored, so he pretends that a wolf is attacking. The villagers come running and praise him, believing his story that the wolf has since run off. The boy enjoys the attention, so he repeats the trick; but this time he is not praised and not believed. When a wolf really does attack the villagers do not come, thinking that the boy is fooling them again.
