Teasing includes light and affectionate parody, good-humoured mockery, simple one-dimensional poking fun, and benign spoofs. Teasing typically consists of an impersonation of someone monkeying around with his exterior attributes, tics, physical blemishes, voice and mannerisms, quirks, way of dressing and walking, and/or the phrases he typically repeats. By contrast, teasing never touches on the core issue, never makes a serious criticism judging the target with irony; it never harms the target's conduct, ideology and position of power; it never undermines the perception of his morality and cultural dimension. "Sfottò" directed towards a powerful individual makes him appear more human and draws sympathy towards him. Hermann Göring propagated jests and jokes against himself, with the aim of humanizing his image. Types of satire can also be classified according to the topics it deals with. From the earliest times, at least since the plays of Aristophanes, the primary topics of literary satire have been politics, religion and sex. This is partly because these are the most pressing problems that affect anybody living in a society, and partly because these topics are usually taboo. Among these, politics in the broader sense is considered the pre-eminent topic of satire. Satire which targets the clergy is a type of political satire, while religious satire is that which targets religious beliefs. Satire on sex may overlap with blue comedy, off-color humor and dick jokes. Scatology has a long literary association with satire, as it is a classical mode of the grotesque, the grotesque body and the satiric grotesque. Shit plays a fundamental role in satire because it symbolizes death, the turd being "the ultimate dead object". The satirical comparison of individuals or institutions with human excrement, exposes their "inherent inertness, corruption and dead-likeness". The ritual clowns of clown societies, like among the Pueblo Indians, have ceremonies with filth-eating. In other cultures, sin-eating is an apotropaic rite in which the sin-eater (also called filth-eater), by ingesting the food provided, takes "upon himself the sins of the departed". Satire about death overlaps with black humor and gallows humor. Another classification by topics is the distinction between political satire, religious satire and satire of manners. Political satire is sometimes called topical satire, satire of manners is sometimes called satire of everyday life, and religious satire is sometimes called philosophical satire.
