Who has a good joke? Give me some.

Five years ago, I bought a 400,000 house for my mistress to live in. Give your mistress 3000 yuan a month. Broke up with mistress this year and sold the house. Sold 1.2 million, worked for more than 6 years as a mistress, and finally earned 600 thousand. Thank the people and the party. Thanks to the real estate agent. It turns out that mistresses are also an investment. Then my wife found out and slapped me. Why did you only install one?
