This thesis uses a conversation analytic (CA) approach to analyze the function of laughter in organizing live improv performances, focusing on laughable turns. In particular the study examines the role of play frames in laughter. Play is defined by nonserious sequences signaled by metacommunication or contextualization cues. These cues act in conjunction with projectability strategies used by performers to 'find' or coconstruct the 'game of the scene,' which is defined by repetition of nonserious behavior. The study uses CA methods to analyze transcribed video tape data of performances of a local Athens improv troupe. The study concludes that audience members rely on projectable cues to sequence enmasse turntaking and performers make heavy use of metamessages to signal salient patterns to fellow performers. In conjunction, projectability and paralinguistic cues combine to describe how improvisers identify and repeat patterns to play conversational 'games.'
