What are the classic jokes in your major?

We major in economic management. When I was in macroeconomics, I had a class about gross national product (GDP), and my tutor told a joke. Two local tyrants bet that A said to B, "If you dare to eat that shit, I will give you 10 million." B hesitated, but still ate that shit for 10 million. After a while, they saw another piece of shit, so B said to A, "You don't have to give me 10 million yuan if you eat that piece of shit, so we are even." A thought about it, thought it was worth it, and ate the shit. After a while, both of them felt something was wrong. Each of them ate a lump of shit, but they didn't get anything else. So they asked the economics professor. After hearing this, the professor excitedly praised them: "I thank you on behalf of the motherland and the party." In a short period of time, you only ate two pieces of shit and easily created an output value of 20 million for the national GDP. "

Another professor of securities investment told us another joke in class. A monk asked a young man, "Which do you choose, a fishing rod or a basket of fish?" The young man said, "I choose a basket of fish." The monk smiled and shook his head and said, "The benefactor only looks at the present. It is better to teach people to fish than to teach them to fish. I've heard of this. The fishing rod can catch a lot of fish, but when you finish eating, you will lose them. " The young man also smiled and shook his head and said, "I sold this basket of fish and bought some fishing rods." Then rent fishing rods to other people who want to fish, and the scale is getting bigger and bigger. Then, there will be another fishing competition. As a gaming company, everyone can bet on who will win the championship. The champion has already been decided, but I have released false inside information, so I will definitely win this bet. " After hearing this, the monk was surprised. It turned out that he lost the bet on horses like this.
