Once upon a time there was a little shepherd boy who had a very bad habit. He would be out in the fields, tending the sheep when suddenly he would cry out.
The townspeople would all grab their guns and run out to the fields, ready to fight. But there was never any wolf. They would only find the little shepherd boy rolling on the ground, laughing like crazy.
Finally, the townspeople had enough of this. They all got together and shipped the boy off to drug rehab. He returned clean and sober and his hands no longer shook. He went back to tending the sheep and never saw wolves again.
