I can't understand this joke! !

1. In order to show that this is a cold joke, two creatures living in cold areas are specially chosen as the protagonists.

And the two protagonists are one in the South Pole and the other in the North Pole. It really takes a long time for penguins to walk so slowly and so far. It is difficult, so to speak, to get there, because he has to go through temperate and tropical zones, land and sea, countless countries and countless unknown difficulties and obstacles waiting for him.

Penguins have been walking like this for many years and have crossed the equator. When they were about to approach the Arctic Circle, it suddenly occurred to them that the natural gas in their home was irrelevant. It can be said that the reflex arc is too long and the reflex nerve is too slow. Well, since I decided to go back, it took me several years to walk back, turn off the gas, and then come back to find the polar bear.

From here, we can see the indomitable spirit of penguins and the process of penguins' unremitting pursuit of their goals. This is a great long March. Penguins are working hard for their dreams of life. He didn't give up in the face of setbacks. Faced with a major mistake (forgetting to turn off the gas), he resolutely chose to go back to the starting point to deal with all the problems before starting again. At this moment, I was in tears.

Well, our hero, Mr. Penguin, finally reached the North Pole and found the home of the polar bear. He is only one small step away from realizing his ideal in life. Just before he knocked, he thought a lot about what happened after knocking, even after he finished with the polar bear. Where should he go? He was at a loss. He stood at the door of the polar bear's house, but he was lost at the fork in the road of life. Suddenly, he found that he couldn't knock, because as soon as he knocked, whether the polar bear played with him or not, he would immediately erase the direction of his life, and his life would become meaningless. A penguin with no ideal and no direction in life is better dead than alive. So, he made a decision at this moment. Go home, turn on the gas, and then come and play with polar bears.
