What is the funniest joke?

Four priests Tang went to travel by plane, and the plane crashed on the way, but there were only three parachutes.

So, the Tang Priest said, let's answer the question, and jump if we can't answer it.

Tang Priest: Wukong, how many suns are there in the sky?

Wukong: One.

Tang Priest: OK, here you are.

Tang Priest: Friar Sand, how many moons are there in the sky?

Friar Sand: One.

Tang Priest: OK, I'll give you one, too.

Bajie on the side is so happy, such a simple question.

Tang Priest: Bajie, how many stars are there in the sky?

....

Bajie jumped down.

Before long, the four of them flew to travel again. They crashed on the way and there were still only three parachutes.

They went on answering questions.

Tang Priest: Wukong, when was People's Republic of China (PRC) founded?

Wukong: 1949.

Tang Priest: OK. Here you are.

Tang Priest: Friar Sand, how many people died in the Liberation War?

Friar Sand: 2.5 million people.

Tang Priest: OK, I'll give you one, too.

Tang Priest: Bajie, what are the names of those 2.5 million people?

..... Bajie had to jump again.

The third time, the four of them traveled by plane again and had an accident on the way.

Then Pig said, Master, you don't have to ask. I jump by myself.

Then jump.

Tang Priest put his hands together: Amitabha, there are four parachutes this time.
