The joking relationship is in some ways the exact opposite of a contractual relation. Instead of specific duties to be fulfilled there is privileged disrespect and freedom or even licence, and the only obligation is not to take offence at the disrespect so long as it is kept within certain bounds defined by custom, and not to go beyond those bounds. (Radcliffe-Brown 1940: 209)
