This study investigated the experience of humour of people with Asperger s syndrome. It aimed to explore the lived experience of this phenomenon. People with Asperger s syndrome are thought not to have a sense of humour and a number of theories are proposed to explain the difficulties that may be experienced in regard to humour. In order to gain insight into the lived experience a qualitative approach was adopted. Interpretative Phenomenological Analysis was then used to illuminate the insider perspective . The analysis highlighted four main themes, the experience of difference, the experience of learning, what I find amusing and how I use humour. The study highlighted a number of clinical implications such as the role humour plays in social interactions and the importance of asking questions rather than making assumptions when working with people with Asperger s syndrome.
