How to write a joke?

A butcher came back at night, and the meat in his burden had been sold out, leaving only bones. The butcher met two wolves on the road and followed (him) for a long way.

The butcher was afraid and threw the bone to the wolf. One wolf stopped when he got the bone, and the other wolf followed. The butcher threw the bone out again, and then the wolf who got the bone stopped, and so did the wolf who got the bone before. The bones were gone, but the two wolves chased the butcher together as before.

The butcher felt critical and worried about being attacked by wolves before and after. He looked around and found a wheat field in the field. The owner of the wheat field piled firewood in it and built it like a hill. The butcher then ran over, leaned over the firewood pile, unloaded the burden and picked up the butcher knife. The two wolves dared not go forward and stared at the butcher.

After a while, one wolf went straight away, and the other wolf squatted in front like a dog. After a while, the wolf sitting there seems to close his eyes and look relaxed. The butcher suddenly jumped up, cut off the wolf's head with one knife, and killed the wolf with several knives. Just as he wanted to leave, he turned and looked behind the haystack. Another wolf is digging a hole, trying to dig a hole from the haystack and attack the butcher from behind.

The wolf's body has gone halfway, showing only his ass and tail. The butcher cut off the wolf's hind legs from behind and the wolf was killed. He realized that the wolf in front pretended to sleep, which was originally used to lure the enemy.

Wolves are also very cunning, and both wolves were killed in the blink of an eye. How many tricks can animals use? It's just a joke.
