This inquiry deals with the interactional achievement of storytelling in French face-to-face conversations. Employing the Corpus of Interactional Data, it asserts that conversational storytelling can now be reported in a more quantitative perspective in the scope of the new corpus-pragmatics approach. Laughter, turn, and morpho-syntactic information are explored. It is assayed to what degree the temporal evolution of these elements within speech production of each speaker throughout narratives supplies evidence in favor of joint activity, i.e. co-narration systematically carried out by both participants and ending in a specific turn-taking organization.
