Please tell me that you have heard a particularly cold joke.

One day, the teacher took a group of children to the mountain to pick fruit. He announced: "children, after picking the fruit, we can wash it together, and we can eat it together after washing." All the children went to pick fruit. As soon as the assembly time came, all the children got together. Teacher: "Xiaohua, what do you have?" Xiaohua: "I am washing apples because I picked them." Teacher: "What about you, Xiaomei?" Xiaomei: "I'm washing tomatoes because I picked tomatoes." Teacher: "The children are great! What about Amin? " A-Ming: "I'm washing cloth shoes because I stepped on shit."
