Once upon a time...
There was once upon a time a witch, who in the shape of a hawk used every night to break the windows of a certain village church. In the same village there lived three brothers, who were all determined to kill the mischievous hawk. But in vain did the two eldest mount guard in the church with their guns; as soon as the bird appeared high above their heads, sleep overpowered them, and they only awoke to hear the windows crashing in.
Then the youngest brother took his turn of guarding the windows, and to prevent his being overcome by sleep he placed a lot of thorns under his chin, so that if he felt drowsy and nodded his head, they would prick him and keep him awake.
The moon was already risen, and it was as light as day, when suddenly he heard a fearful noise, and at the same time a terrible desire to sleep overpowered him.
