The body of this paper was interesting and relevant, but I felt the introduction dragged on for too long without explaining what the research was. There were still sentences saying "the focus of this paper" already on page 5, making me wonder at what point we would get to the purpose of the paper rather than talking about the purpose of the paper. I think readers will be interested to learn about the use of humor in the different countries, so putting a line about the work in India, Turkey, and the United States directly in the opening thesis will grab the readers' attention and make it clearer what the research performed actually was. I felt the introductory paragraph explaining that language and humor are important was unnecessary--your readers already know this, and the parts about Plato and Aristotle, while interesting, do not add new information. My suggestion would be to shorten or remove these sections in favor of a clear, concise thesis or abstract within the first page letting readers know what the experimental design was. There were also some proofreading issues--for one, switching between "the researcher" and 1st person partway through, and a few missing words. I would have liked more details about the author's suggestions for positive uses of humor--this is briefly mentioned before the conclusion but I would have liked more citations strengthening this, e.g., rather than saying an intentional use of humor "might create a more positive atmosphere", is there some other study showing that this does work, and if so, how was it implemented? 

I enjoyed the overall intent. I wish you would have gone a little more into the idea of the subjective nature of humor. There are elements of humor (dark or black humor, self-deprecation, etc) that some individuals find to be humorous while others do not. I do not think that the methodology did enough to discuss these differences in sense of humor. I also wish there was a greater discussion of how demographics perceive jokes and humor differently. Individuals from one particular culture may not joke on a subject as much as others in a different culture (this is hinted at with the discussion of a lack of religious humor) but considering the subjects are rather homogeneous (high school students), I am afraid that their sense of humor is not as connected with the researchers methodology as they hope.
