This article describes the rationale for and use of a class innovation the authors call "professor delight." This inexpensive, high-yield concept allows students and professors to enact their understanding of citizenship throughout the term, and often beyond. The authors explain the concept, describe its implementation in class, and link it to the literature on organizational citizenship behavior (OCB). They offer extensive examples of professor delight behaviors aligned with their corresponding theoretical OCB dimensions and provide venues for future research in OCB and positive organizational scholarship.
