Ancient homophonic jokes

Ancient homophonic jokes are as follows:

Loquat is not this pipa.

Once upon a time, there was a dude who was lazy and didn't study hard. When I grow up, I often make jokes because I write typos. One day his wife said she wanted to eat loquat. He took a piece of paper from the table and wrote some words on it with a pen. After writing, he asked the servant to buy loquat. His wife took the newspaper and read it. She burst out laughing.

It turned out that it said "buy five catties of pipa". Two of the five words are misspelled, and the word "loquat" is misspelled as "pipa". After reading it, his wife wrote a jingle at the back: loquat is not this pipa, just because she can't read much. If the pipa can bear fruit, the city will be full of flutes and drums.
