THE Jokes

A jokes are short story or ironic depiction of a situation communicated with the intent of being humorous. These jokes will normally have a punch line that will end the sentence to make it humorous. A joke can also be a single phrase or statement that employs sarcasm. The word joke can also be used as a slang term for a person or thing which is not taken seriously by others in general or is known as being a failure. A practical joke or prank differs from a spoken one in that the major component of the humour is physical rather than verbal (for example placing salt in the sugar bowl).
Marvin Minsky suggests that laughter has a specific function related to the human brain. In his opinion jokes and laughter are mechanisms for the brain to learn nonsense. For that reason, he argues, jokes are usually not as funny when you hear them repeatedly.

Edward de Bono in "The Mechanism of the Mind" (1969) and "I am Right, You are Wrong" (1990).

Edward de Bono suggests that the mind is a pattern-matching machine, and that it works by recognizing stories and behaviour and putting them into familiar patterns. When a familiar connection is disrupted and an alternative unexpected new link is made in the brain via a different route than expected, then laughter occurs as the new connection is made. This theory explains a lot about jokes.
