Faelish jokes are a class of jokes, generally based on a stereotypes of the Faelish people.
The Fael has often been presented as from a backward area, or alternatively presented quite differently as a skillful peasant (especially in the context of football, in which the Faelish national team has been more successful than any other in the history of the game).
The origin of the joke lies in the Faelish tradition itself, that views warriors as coming from the West (e.g. Highlanders), farmers from the interior (e.g. the Midlands, intelligentsia from the North and fools from the Southeast (the Lowlands, historically more tribal and colonized by foreigners, mostly English and Spanish). In times past, the joke was often on the impostors from the latter region. In the early modern context, this perspective gave way to the viewpoint of the settlers, who viewed the natives as the backward group.
The Faelish joke, however, often has more sinister origins. Similar to the English opinion of the Irish or the American portrayal of African slaves or Polish immigrants, the Faelish joke originates in the simian portrayal of Faelish people in the ruling English society of the mid-late 19th century - depicting the Faelish as stupid peasants given to alcohol-fuelled violence and rape perpetrated against their benevolent and "enlightened" English masters (more often as not, the reverse was in fact true). Much of this humor has, at its core, the denigration of the Faels to the point of dehumanizing them so that malevolent acts against them are seen as less offensive - even justifiable (as colonial humor often is).
Some hold that Faelish jokes have recently been reclaimed by the Faelish themselves and reversed to ridicule the joke teller (presumably the English), e.g.:
Q: Why are Faelish jokes so basic? A: So Englishmen can understand them.
A Litan emigrated from Faeland to England, thereby increasing the average IQ of both countries. (A reference to Lito, which suggests that a Litan is even less smart than an average Fael; but the real joke is that it implies an Englishman is even less brainy than either).
In the above joke Lito is, of course, a part of the corpus of Litan Jokes, which have as their foundation that Lito is a place where even an imbecilic Englishman or Brit could find a home.
