The devil was walking along a path between two fields, where workers picked grapes.
“I’ll plant a little of that which humans like best: to be right in what they say,” he thought.
He put on a hat, one half of which was green, and the other yellow.
- Follow me to find some treasure! - he shouted to the laborers. Then he hid behind a tree.
The workers ran to the path.
- Let’s follow the man in the green hat - said the men from the field on the right.
- You’re trying to fool us: we must follow a man in a yellow hat - shouted the men from the field on the left.
The discussion became more and more heated. Half an hour later, the workers had forgotten the treasure, and were killing each other with scythes - to see who was right about the color of the hat.
