Theories of language usually deal with relatively 'pure' instantiations of language; therefore, they are not involved with something like laughter. What cannot be expressed in language univocally, is no part of the research topic. Because of this exclusion of laughter, a serene seriousness reigns within 'language'. Both 'ideal' languages and everyday 'communication' presuppose a quite abstract, univocal society. This theoretical promotion of seriousness can be broken from the point of view of Wittgenstein's scepticism with regard to rules and Saussure's research of anagrams.
