The funniest joke ever! ! !

One day, the teacher asked Xiao Ming what one plus one equals. Xiao Ming didn’t know, so the teacher asked him to ask at home. As soon as Xiao Ming came home, he asked his mother who was playing mahjong. His mother called out: "A dragon." Then he went to ask his father. His father was reading the newspaper and shouted: Zhou Enlai. He asked his brother again. His brother was drinking soda and said: It feels so good. Finally, he asked his sister. My sister was saying goodbye to her boyfriend and said: Bye. The next day, he went to the teacher's office. The teacher asked: What does one plus one equal? He answered: A dragon. The teacher asked: Who said that? He answered: Zhou Enlai. The teacher gave him a mouthful and he said: It feels so good. Finally the teacher yelled: Get out of here! He said: Bye~~~~~
