A joke is a display of humour in which words are used within a specific and well-defined narrative structure to make people laugh and is not meant to be taken seriously. It takes the form of a story, usually with dialogue, and ends in a punch line. is in the punch line that the audience becomes aware that the story contains a second, conflicting meaning.This can be done using a pun or other word play such as irony, a logical incompatibility, nonsense, or other means. Linguist Robert Hetzron offers the definition.It is generally held that jokes benefit from brevity, containing no more detail than is needed to set the scene for the punchline at the end.
