At the class reunion, I told a joke that everyone thought was not funny, but one of them thought it was funny and told it again. This is a big joke.

When a joke is told by different people, the effect is different, which is related to language, intonation, rhythm and level, and expression. Of course, there is another reason. Your friends are more influential in your team than you are. Besides, he is a very clever man and can find places that others can't.
