Looking for a fable about the king and a group of lunatics

Once upon a time, a majestic and clever king ruled the distant city of vilani. His majesty makes people fear and his wisdom makes people love.

At that time, there was a well in the city center, which was clear and transparent. All the residents in the city, even the king and ministers, drink the water from this well, because it is the only well in the city.

One night, when everything on the earth fell asleep, a witch entered the city, dropped seven drops of magical liquid in the well, and then said, "From now on, whoever drinks the water from this well will go crazy." 」

The next morning, except the king and the guards, all the residents drank the water from the well, and everyone became crazy as the witch predicted.

On this day, in the narrow streets and markets, people were whispering and doing nothing: "The king is crazy, our king and guards are crazy!" " We can't let a crazy king rule this country, we must depose him. 」

That night, the king took a golden cup of water from the well. As soon as the water arrived, the king took a swig and gave the rest to the guard.

Therefore, the faraway city of vilani celebrated warmly, because their king and his guards came to their senses again.
