“All practical jokes, friendly, harmless or malevolent, involve deception, but not all deceptions are practical jokes. The two men digging up the street, for example, might have been two burglars who wished to recover some swag which they knew to be buried there. But, in that case, having found what they were looking for, they would have departed quietly and never been heard of again, whereas, if they are practical jokers, they must reveal afterwards what they have done or the joke will be lost. The practical joker must not only deceive but also, when he has succeeded, unmask and reveal the truth to his victims. The satisfaction of the practical joker is the look of astonishment on the faces of others when they learn that all the time they were convinced that they were thinking and acting on their own initiative, they were actually the puppets of another’s will. Thus, though his jokes may be harmless in themselves and extremely funny, there is something slightly sinister about every practical joker, for they betray him as someone who likes to play God behind the scenes. […] The success of a practical joker depends upon his accurate estimate of the weaknesses of others, their ignorances, their social reflexes, their unquestioned presuppositions, their obsessive desires, and even the most harmless practical joke is an expression of the joker’s contempt for those he deceives.”

“As his wife, Emilia must know Iago better than anybody else. She does not know, any more than the others, that he is malevolent, but she does know that her husband is addicted to practical jokes. What Shakespeare gives us in Iago is a portrait of a practical joker of a peculiarly appalling kind, and perhaps the best way of approaching the play is by a general consideration of the Practical Joker.”

“Practical jokes are a demonstration that the distinction between seriousness and play is not a law of nature but a social convention which can be broken, and that a man does not always require a serious motive for deceiving another.Two men, dressed as city employees, block off a busy street and start digging it up. The traffic cop, motorists and pedestrians assume that this familiar scene has a practical explanation – a water main or an electric cable is being repaired – and make no attempt to use the street. In fact, however, the two diggers are private citizens in disguise who have no business there.All practical jokes are anti-social acts, but this does not necessarily mean that all practical jokes are immoral. A moral practical joke exposes some flaw of society which is hindrance to a real community or brotherhood. That it should be possible for two private individuals to dig up a street without being stopped is a just criticism of the impersonal life of a large city where most people are strangers to each other, not brothers; in a village where all inhabitants know each other personally, the deception would be impossible.”

“The practical joker despises his victims, but at the same time he envies them because their desires, however childish and mistaken, are real to them, whereas he has no desire which he can call his own. His goal, to make game of others, makes his existence absolutely dependent upon theirs; when he is alone, he is a nullity. Iago’s self-description, I am not what I am, is correct and the negation of the Divine I am that I am. If the word motive is given its normal meaning of a positive purpose of the self like sex, money, glory, etc., then the practical joker is without motive. Yet the professional practical joker is certainly driven, like a gambler, to his activity, but the drive is negative, a fear of lacking concrete self, of being nobody.”

“As I remember his laugh, there was nothing mad about it, it was more like the laugh of someone who has been the victim of a practical joke, a farce in which he had believed until suddenly he realized his folly.”

“The joke loses everything when the joker laughs himself.”
