What do you mean, others are holding donkeys and you are pulling pegs? What is metaphor?

There is a joke about two thieves trying to steal a farmer's donkey. As a result, one of the thieves took the lead, untied the reins tied to the donkey and stole it. Another thief came and saw that the donkey was gone. According to the thief logic of "thieves enter the house empty-handed", he began to pull wedges into the underground pegs. But before he succeeded, he was caught by farmers and wanted to hand him over to the government for stealing donkeys. Seeing this scene, it was difficult for the thief to defend himself, so he had to admit his bad luck and obediently accompany the farmer's donkey, which was laughed at by everyone. From then on, there was a joke that "a man took the donkey away and he pulled the pegs behind him". It is intended to remind some ignorant and stupid people not to make low-level and simple similar mistakes, not to mention adding mistakes to them.
