'Face with tears of joy' (1F602), a face laughing so hard that it cries, is one of the most popular emojis on many platforms. This paper analyzes the use of this pictograph in a corpus of dyadic WhatsApp chats using digital conversation analysis. In particular, it compares the use of this emoji on WhatsApp with the sequence organization of laughter in face-to-face in-teraction. Two patterns of use are found: when placed at the end of the utterance, the emoji 'face with tears of joy' usually signals the 'laughable' and indexes an invitation to laugh, while the acceptance of the invitation is usually performed by repeated 'face with tears of joy' emojis standing alone. Be-sides contributing to literature on the interactional functions of emojis, these findings have implications in training auto-matic emoji classifiers or in improving social media market-ing and chatbot systems.
