They all tell a joke. I think that one is funny.

1. Liu Bei, Zhuge Liang, Sun Quan and Cao Cao were traveling by plane. They encountered an accident and only had three parachutes. Zhuge Liang suggested: "I ask questions and you answer them. Whoever can't answer will not have a parachute." The three agreed. Ask Liu Bei: "How many suns are there in the sky?" "One." Ask Sun Quan: "How many moons are there?" "One." Ask Cao Cao: "How many stars are there?" "..." Cao Cao was thrown down.

2. Cao Cao was lucky last time and did not fall to death. The four of them traveled together again. Encountered the same problem. Zhuge Liang asked Liu Bei: "What was the most critical battle in King Wu's defeat of Zhou?" "The Battle of Muye." Asked Sun Quan: "Approximately how many people died?" "Forty to fifty thousand." Asked Cao Cao: "What were the names of the people who died? "..." Cao Cao was thrown out again.

3. Cao Cao did not fall to death again, and the four of them went out again. The plane had another accident. Cao Cao thought, I am going out anyway, so I might as well jump off by myself! After Cao Cao jumped, Zhuge Liang wondered: "Why did he jump with four parachutes this time?"

4. Cao Cao did not fall to death again, and the four of them went out again. The plane had another accident. Cao Cao thought that he would not be able to jump again this time, so he went to the bathroom, and Liu Bei, Zhuge Liang, and Sun Quan jumped with parachutes. Cao Cao was sitting on the toilet feeling proud when the plane crashed!

5. Cao Cao did not fall to death. The four of them continued walking together, but encountered another plane failure. Kong Ming first asked Liu Bei: "Seven (riding) monkeys on the tree, one monkey on the ground, how many monkeys are there on the ground?" Monkeys?" While Liu Huangshu was thinking, Cao Cao responded: "If it's seven monkeys, it's eight monkeys, if it's riding one monkey, it's two monkeys." Liu and Sun looked at each other, and Kong Ming was stunned, and he was proud of Cao. He picked up the only parachute bag on his back, clasped his fists with both hands and said "Sayounala" before jumping down.

At this time, the mechanic climbed out from the bilge and said: "The fault has been eliminated. Have any of you seen my tool bag?..."
