The really silly shepherd

Sam the Silly Shepherd found three baby wolf cubs left all alone by their mother. He remembered how the big bad wolf had eaten all his sheep once before, but then he had another of his silly ideas. "If I look after these cubs myself, they'll grow up kind and gentle," he thought. So he fed them by hand and gave them toys to play with, and day by day they grew bigger and bigger. At last they were the same size as their father, the big bad wolf, and they immediately attacked the sheep and killed them. But as they're three times faster than their father.
