What cold jokes have you heard that are particularly memorable?

At a class reunion, a very funny classmate told us a cold joke that impressed me deeply. The robber robbed a short man on the road. Afraid of being recognized, I had to cut off the short man's head. The short man said. I'm already so short. If you cut off my head, I will be shorter. How to meet people in the future? The robbers thought about it and let the short man go. Another time, my mother told a joke at dinner. After eight years of anti-Japanese war, Xiaoming was hungry. He packed minced meat for breakfast, jiaozi. When he got to school, he opened his lunch box and found that two jiaozi were missing. He closed it and opened it again, missing two jiaozi. In the end, all his jiaozi was gone. Xiaoming is afraid. Jiaozi is glued to the lid of the lunch box. There are many times when a cold joke can ease the embarrassment.
