Case wit

Case wit is a wide-spread humorous notion that is represented through several main literary devices. One of the coarsest types of wit (the least used) is the practical joke. It is a joke made at the proper moment of some event and sometimes pretty efficaciously used by humourists.
The witty effect of case or situational wit is usually achieved through combination of subtle mind and inert alert. According to Henri Bergson's theory of laughter, this phenomenon is used to explain all varieties of the comic.
There are some other kinds of case wit among which are imitation, impersonation, and disguise. The impersonator demonstrates both himself and somebody else at the same time. The show may be degrading to a certain degree. Still, it almost always enjoys success.
The most aggressive but most successful form of impersonation is parody. Through laughter and comism, it does its best to reveal the very nature of the depictured object. The central effects of the parody are playful behaviour, mimics and gestures.
Cicero and Francis Bacon considered "deformity" to be the most frequent reason for laughing. According to them, deformities might cause a humorous effect of the bomb that might explode.
"Changing the role of the part and the whole" is one more source of innocent situational wit. The attention is concentrated on a detail that is taken out of the functional context that determines its meaning.
So, these are the main forms of the case wit that constitute the majority of the modern case wit.
