Nurse teachers can often find themselves in various situations where they resort to using humour. An exploration of the role of humour within the educational relationship between nurse teachers and nursing students is the focus of this paper. Consideration is given to the nurse teachers' requirement to develop self-awareness in their own understanding of humour in order to facilitate and recognize the reasons for the nursing students' use of humour. The development of the appropriate use of humour by nursing students may lead to enhanced nursing practice, thereby reinforcing the need for inclusion of the theory of humour in both teacher training and the nursing curriculum.
