A joke is a short story or short series of words spoken or communicated with the intent of being laughed at or found humorous by the listener or reader. This sort of "joke" is not the same as a practical joke.
Laughter, the intended human reaction to jokes, is healthy, uses the stomach muscles, and releases endorphins, natural happiness-inducing chemicals, into the bloodstream. Daily laughter is recommended to every human being. Jokes have been the subject of serious academic study, a notable example being Sigmund Freud's "Jokes and Their Relationship to the Unconscious".

Blonde jokes are jokes about people, generally women, who have blonde hair and are assumed not to be very smart. These jokes are generally considered to be derogatory, but are usually taken with good humor. They are usually variants on traditional ethnic jokes.
A sexist joke is one that expresses the sexist belief that one gender or sex is somehow superior to the other.
Examples
;How do you fix a woman's watch?
An ethnic joke relies for humorous effect on stereotypes about particular ethnicities, often those from different (neighbour) nations or minorities. For example Finns tell jokes about Swedes and Gypsies. Sometimes they are considered in good taste, meant to poke fun at about another culture, while other times they are considered offensive or racist. Sometimes the difference between the two judgements is in the nature of the joke itself, and sometimes the difference is in the perception of those hearing it.
In an attempt to preserve the humor of ethnic jokes without their derogatory nature, on rare occasions such jokes are told with the word ethnic or some variant in place of the nationality of the subject. For example: "Two ethnics are out duck hunting. They hunt and hunt and hunt and still have not killed one duck. Finally, ethnic #1 says to ethnic #2: 'Maybe we'd do better if we threw the dog up higher.' " Another twist is letting people of that same target group enjoy a monopoly on telling jokes about themselves.
Examples
Playing the dozens is one slang term for the verbal game played by African-American men in which they take turns telling one-line jokes to each other that insult their mother or another family member. The object of the game is to tell the best joke, usually after each person has been given twelve tries.
Examples
Your Mama is so fat...
Political jokes tell about politicians and heads of states.
Examples
;Why did the chicken cross the road?
;Why did the tachyon cross the road?
These target the perceived flaws of people in certain trades. Lawyer jokes are traditionally popular in the United States.
Italians trade jokes about the Carabinieri national police force, and this fact is rather good-humouredly acknowledged even in the force's own website, probably because the Carabinieri know that, jokes aside, they do enjoy a high degree of respect. Carabinieri are factually known to be occasionally willing tell a few such jokes themselves. It is also known that they have a small office in Rome devoted to tracking, developing and collecting jokes (but this is a joke).
