The purpose of the present study was to investigate 2042 junior high school students, responses to 12 sexual jokes. These jokes were classified into three categories: sexual organs, sexual intercourse, and sexual implication. The responses include three deimensions: funniness, embarrassment, and anger. Sixty-four percent of the subjects could understand all of these 12 jokes. There was no gender difference among the 7th graders. For the 8th and 9th graders, more male students understood all jokes than females. Overall, the subjects reported that they felt somewhat funny, a little embarrassed, and a little angry about these jokes. The more embarrasing the subjects felt, the more angry they were. Females felt more embarrasing and angry, but less funny, than males. Subjects indicated that sexual organs jokes were funnier and more embarrassing than sexual intercourse jokes, and that sexual implication jokes were the least funny. Sexual intercourse jokes provoked more angry responses than others.
