Who has some funny idioms?

Idiom story:. Steal my light by poaching: In the Han Dynasty, there was a young man named Kuang Heng who was very studious. In the evening, because his family was poor and couldn't afford to light candles, he quietly cut a small hole in the wall and read books by his neighbor's candlelight ... Nephew: Wait, why didn't he turn on the light? Me: Because there is no electricity. Nephew: Is it because of the lack of electricity? Me: (panting) No, the Han Dynasty was two thousand years ago, before electricity was invented. Nephew: Oh. (Pause) When did he make the hole? Me: (cold) ah? At night. Nephew: At night? Isn't he invisible at night? How did you chisel it out? Me: (pause) That, that, that is daytime, right? Nephew: Do you still have time to dig a hole during the day? Why not use this time to read? Me: (again) this, this I can't remember clearly. Tell me another story. Kong Rong sent me pears: In the Eastern Han Dynasty, there was a four-year-old child named Kong Rong. When he ate pears, he gave them to adults ... Nephew: Wait, how many adults? Are they his parents? Me: (prepared) I don't know, just one. Nephew: How many small pears are left? Me: (speechless, frowning) like one? Nephew: I see. The big pear must be ripe soon. It's not delicious. The small one must be natural green food ... Me: (I can't wait to slap him) Tell me another one. Cao Chong said to me: During the Three Kingdoms period, there was a child named Cao Chong. A foreigner gave his father an elephant. His father wanted to know how much the elephant really weighed, so he asked Cao Chong to weigh it ... Nephew: Stop it, uncle, I know. Kill the elephant, cut it into pieces and add it up. Me (gloating): (glaring) It's a gift. You can't kill it. Nephew: (Now it's his turn to be speechless) How did the elephant come from? Me: (a little annoyed) Maybe I used the car. Nephew: That must be overloaded. Look at the driver's ticket and you'll know what the weight is!
