Who has a long joke? Not too long but not too short?

Once upon a time, there was a king who had two daughters. When the two daughters reached the age of marriage, the king decided to marry her. On the wedding day, the king said to the prince of the country, if one of you can test the questions I gave, I will marry my eldest daughter to him! So the king asked the guards to take an elephant to the river. Then he said: If anyone can make an elephant jump into the river with his ass covered, I will marry my eldest daughter to him!

All the princes in the world can't think of any way. Just then, a prince from Persia came up to the king and said, If I can do it, will you marry my daughter? Although the king didn't want to marry his daughter to this "black man", he had no choice but to agree.

The prince went to see the elephant and suddenly took out a needle from behind and stuck it in the elephant's ass! When I saw the elephant, I immediately grabbed my ass and picked it up in the river! The king had no choice but to marry his eldest daughter.

When the second daughter got married, the king thought it was not so easy to marry her, so he asked another question: Who can make the elephant nod first, then shake his head, then nod, and then jump into the river, and he married the second daughter!

Coincidentally, it was still the elephant, but the princes of all countries tried their best! Finally, the boss prince came up and said, if I can do it, should I marry my second daughter, too? The king had no choice but to agree.

Prince Bos went to see the elephant. After a while, he said to the elephant, Do you still know me? The elephant nodded. Do you still want to be like last time? The elephant shook his head. Do you know what to do? The elephant nodded again, and then jumped into the river, clutching his ass!
