The long joke story: The test question of the King of laughter

There was once a king who had two daughters, and when they were old enough to marry, he decided to marry them. On the day of the wedding, the king said to the prince of a country: If you want to do a good job of my exam, I will marry my eldest daughter to him! So the king asked his guards to bring an elephant to the river. Then he said, "Whoever can make an elephant jump into the river with his ass covered, I will marry my eldest daughter!"

The princes of all countries could not think of anything to do. Just then a prince of Bose came to the king and said, "Will you give me your daughter if I can do the right thing?" Although the king did not want to marry his daughter to this "black man," he had no choice but to agree.

The prince went and looked at the elephant. Suddenly he took a needle out of his back and stuck it into the elephant's ass! The elephant immediately covered his butt and picked it into the river! The king had no choice but to marry his eldest daughter.

When the second daughter was married, the king thought it would not be so easy to marry his daughter, so he put out another question: who can make the elephant nod first, shake his head, nod again, and then jump into the river, and marry his second daughter!

It happened to be the same elephant, but the princes of all countries could not think of a way! Finally, the prince of Bose came up and said, "If I can do it, shall I marry my second daughter?" The king had no choice but to agree.

Prince Bose went over and looked at the elephant for a moment and said to the elephant, "Do you still know me?" The elephant nodded. Do you imagine what happened last time? The elephant shook his head. Well, do you know what to do? The elephant nodded again, and then jumped into the river with his bottom covered.
