Footnote 37: The word tendency encountered hereafter in the expression “Tendency-Wit” (Tendenz Witz) is used adjectively in the same sense as in the familiar phrase “Tendency Play.” Footnote 38: Cf. my _Psychopathology of Everyday Life_, translated by A.

Footnote 45: If I may be permitted to anticipate what later is discussed in the text I can here throw some light upon the condition which seems to be authoritative in the usage of language when it is a question of calling a joke “good” or “poor.” If by means of a double meaning or slightly modified word I have gotten from one idea to another by a short route, and if this does not also simultaneously result in senseful association between the two ideas, then I have made a “poor” joke. In this poor joke one word or the “point” forms the only existing association between the two widely separated ideas. The joke “Home-Roulard” used above is such an example. But a “good” joke results if the infantile expectation is right in the end and if with the similarity of the word another essential similarity in meaning is really simultaneously produced—as in the examples Traduttore—Traditore (translator—traitor), and Amantes—Amentes (lovers—lunatics). The two disparate ideas which are here linked by an outer association are held together besides by a senseful connection which expresses an important relationship between them. The outer association only replaces the inner connection; it serves to indicate the latter or to clarify it. Not only does “translator” sound somewhat similar to “traitor,” but he is a sort of a traitor whose claims to that name are good. The same may be said of Amantes—Amentes. Not only do the words bear a resemblance, but the similarity between “love” and “lunacy” has been noted from time immemorial.
