Misunderstandings, (_malentendus_) where one person means one thing, and another is aiming at something else, are another great source of comic humour, on the same principle of ambiguity and contrast. There is a high-wrought instance of this in the dialogue between Aimwell and Gibbet, in the Beaux’ Stratagem, where Aimwell mistakes his companion for an officer in a marching regiment, and Gibbet takes it for granted that the gentleman is a highwayman. The alarm and consternation occasioned by some one saying to him, in the course of common conversation, ‘I apprehend you,’ is the most ludicrous thing in that admirably natural and powerful performance, Mr. Emery’s Robert Tyke. Again, unconsciousness in the person himself of what he is about, or of what others think of him, is also a great heightener of the sense of absurdity. It makes it come the fuller home upon us from his insensibility to it. His simplicity sets off the satire, and gives it a finer edge. It is a more extreme case still where the person is aware of being the object of ridicule, and yet seems perfectly reconciled to it as a matter of course. So wit is often the more forcible and pointed for being dry and serious, for it then seems as if the speaker himself had no intention in it, and we were the first to find it out. Irony, as a species of wit, owes its force to the same principle. In such cases it is the contrast between the appearance and the reality, the suspense of belief, and the seeming incongruity, that gives point to the ridicule, and makes it enter the deeper when the first impression is overcome. Excessive impudence, as in the Liar; or excessive modesty, as in the hero of She Stoops to Conquer; or a mixture of the two, as in the Busy Body, are equally amusing. Lying is a species of wit and humour. To lay any thing to a person’s charge from which he is perfectly free, shews spirit and invention; and the more incredible the effrontery, the greater is the joke.
