One day the stupidest and most cunning man in the world met on the road. The cunning looked at the fool from top to bottom and approached him and said hello with a smile.
Seeing this smiling and well-dressed man in front of him, the fool said hello to the cunning and asked what he wanted. The crafty took a chain watch out of his pocket, looked up at the sky and said that his clock had gone off when he had clicked a few clicks on his window.
Then the fool, looking at the clock on his arm, said 14:35. The crafty looked up at the sky again and said that his clock was broken, at most it was 14:40. The fool stared at the sky cunningly for five full minutes.
Then he asked the crafty to take his broken watch to the repair shop.
