China, the United States, Japan, etc. People flowed to a desert island, and when they ran out of ammunition and food, God appeared. God said, I will give you a chance to go home. Here are ten watermelons, ten apples and ten cherries. You choose one and stuff it into PP, and you can go home without laughing. If you laugh, you will die. They agreed, and the Americans chose Pingguo until the third one couldn't help laughing, and he died. China people wisely chose the cherry, stuffed it into the eighth one, and suddenly died laughing. The Americans saw China in heaven and asked him why. The China people said, Shit, I saw the Japanese coming with watermelons.
