This study was to design a humor-creating training course and to explore its effectiveness. In the pilot study, 3218 jokes collected from Internet were reanalyzed by a framework proposed by Chen etc. (1999). Seven most often used humor-creating skills were found: homonym, word-combination, lexical ambiguity, syntactic ambiguity, erroneous inference, reinterpretation, and metaphorical inference. In the formal study, a humor-creating course was set up and 15 students from the Fu Hsing Kang College participated the experimental and control group respectively. Before and after the training course, all participants received a humor-creating test. The results suggested: (a) the frequency of using humor-creating skills was increased significantly in the tests; (b) when the skill is designated, the training effect was found only in word-combination skill condition. However, with no restriction, the experimental subjects scored higher on humor-creating test than the controls; (c) skills of homonym, word-combination, lexical ambiguity and syntactic ambiguity revealed better training effects as compared to others.
