It is this element of unkindness or even cruelty at play in some humour that people often ﬁnd difﬁcult to accept, as for the most part people want to see humour as a positive concept that creates goodwill and enjoyment. However most people (I’m sure) have experienced humour that is harmful, cutting, barbed or even vindictive and it is these aspects that are sometimes neglected in research but they cannot be ignored in a comprehensive discussion of humour theory. In an extensive review of humour theories, sociologist Michael Billig (2005) suggests that early theorists such as Hobbes (1640) and Freud (1905) saw laughter as a rebellious activity rather than the afﬁrmative feel-good experience that is most often portrayed.
Sometimes even targeted jokes about race or sexism are enjoyed and can even foster greater collegiality and inclusion. In some of my earlier research I found that people in most workplaces enjoy ‘taking the piss’ (participants’ phrase) out of each other in a form of targeted humour that jests about highly personal characteristics and behaviours. I found that banter is the most commonly shared form of humour inside the workplaces I studied. The employees that I talked to ardently asserted that being teased by colleagues was a sign of inclusion in their workgroup or team, and those that were not teased were considered ‘outsiders’ in work contexts (see Plester & Sayers, 2007).
Because people generally try to control their sexual or aggressive impulses, laughter offers an acceptable outlet that can relieve tension (Douglas, 1999; Freud, 1905; Raskin, 1985; Weick & Westley, 1996; Wilson, 1979). A release of ‘psychical energy’ occurs when jokes free people from their inhibitions (Freud, 1905: 181) and the joker may be shielded from criticism through the use of humour. Comic relief occurs when humour offers a respite from everyday reality, boredom and even oppression (Westwood, 2004).
