Tell a hilarious joke, don't make it too boring.

A foreigner visited China, entered a stationery store and saw a pencil sharpener in the shape of a car. He said, "Oh, so the pencil sharpener is a car."

A few days later, he saw that the tomatoes in the vegetable market were broken and red juice flowed out. He added, "Oh, so blood is tomatoes."

When I entered the fruit shop, I saw a woman buying a turtle (turtle refers to a kind of fruit) and said, "Oh, all women in China are assholes." Seeing another car hit a woman and shed blood, he called the police and said, "A pencil sharpener killed a bastard and shed tomatoes ..."
