Have you ever made a joke and no one laughed, or heard one that everyone understood but you? These everyday situations may seem simple, but they show how complex humor can be in real conversations. This review talks about the book The Multimodal Performance of Conversational Humor, by Dr. Elisa Gironzetti, which explores how people use humor while talking to each other. The book doesn’t focus on stand-up comedy or jokes with punchlines. Instead, it looks at how humor happens naturally during conversations with words, smiles, facial expressions, and eye contact, with examples from real conversations in English and Spanish, combining language analysis with tools like eye-tracking to understand how humor is created and shared between people. This review analyses each book chapter critically, highlighting its remarks, arguments, findings, and results, and concludes by discussing the book’s overall contributions to ongoing research in this field.
