When a group of people laugh, people will look at the person they feel closest to in that group due to interest indicators per supporting research by Norman P. Li et.al. in 2009 . "Humor plays a large role in our everyday lives and is pervasive across all cultures. We seek and rapidly notice humor whether we are going to the movies, interacting with a stranger or a friend, or looking for a potential romantic partner ." The interest indicator model suggests that humor can function as a key tool for both facilitating and maintaining social relationships within a group of people. The interest indicator model also proposes that humor is inherently different from intelligent conversation and serves an important function beyond courtship or intrasexual competition. Humor also functions to indicate interest in social relationships to initiate new relationships and to monitor existing ones. Co-e
