Abstract: A sense of humor is considered as a lubricant for interpersonal communication. Many humor theories are created with the influence of Grice’s cooperative principle. This paper is going to give a brief introduction to the cooperative principle and its four maxims: maxim of quantity, maxim of quality, maxim of relation and maxim of manner at beginning, and specifically illustrate how the humor is created when the violating of maxims takes place. Through the illustration we claim that the analysis on cooperative principle and its maxim is not only to facilitate a smooth and harmonious conversation but to stimulate humorous interlocution. So this analysis is of great value for us to learn to be humorous. In addition, this also helps the English learner appreciate the essence of English humor and the western culture.
