Topical humor
The topical humor and topical jokes is humor framed around a specific topic related to current events or dealing with issues that are important or popular at the current time. The value of this kind of humor often diminishes when the topic is no longer widely discussed in public.
Besides jokes, topical humor may be in forms of news parody, "Top 10" lists, demotivators, cartoons, etc. Sometimes old jokes may be turned into topical ones due to the newly acquired salience.
Liisi Laineste of Estonian Literary Museum writes that topical jokes and news parodies emphasize the need to look critically at the flow of the news.
Sigmund Freud
described the "topicality" aspect of jokes in his book Jokes and Their Relation to the Unconscious:
There are jokes which are completely independent of this condition, and in a monograph on jokes we are obliged to make almost
exclusive use of examples of that kind. But we cannot forget that, in comparison with these perennial jokes,
we have perhaps laughed even more heartily at others which it is difficult for us to use now because they
would call for long commentaries and even with such help would not produce their original effect. These
latter jokes contained allusions to people and events which at the time were ‘topical’, which had aroused
general interest and still kept it alive. When this interest had ceased and the business in question had been
settled, these jokes too lost a part of their pleasurable effect and indeed a very considerable part.
