The type of humour that deals with creating laughter at the expense of the person telling the joke is called reflexive humour. Reflexive humour can take place at dual levels of directing humour at self or at the larger community the self identifies with. The audience's understanding of the context of reflexive humour is important for its receptivity and success. Satire is found not only in written literary forms. In preliterate cultures it manifests itself in ritual and folk forms, as well as in trickster tales and oral poetry.
