Two Connecticut College psychologists (Murstein, Brust) asked thirty couples - twenty-six single, four married, mostly college age - to rate the humor in twenty-five jokes, cartoons, and comic strips. The study showed that couples who agree on what's funny are more likely to like, love, and want to marry each other than those who didn't laugh at the same things. Moreover, it found that couples with a common sense of humor tended to have been together longer than the others. A shared sense of what's funny, say the authors, "is indicative of many things: values, interests, preoccupations, intelligence, imagination, and needs."
