One hilarious and stupid joke is, "what do you call a bear with no teeth? A gummy bear." "What do you call a sleepwalking nun? A Roamin' Catholic" and "I think I want a job cleaning mirrors, it's something I could really see myself doing" are some other hilarious, stupid jokes.
A joke usually takes the form of either a short story or a question followed by an answer. Every joke includes a punch line, which is a word or phrase that triggers a sudden shift in the listener's understanding of the narrative to something unexpected. The critical analysis of jokes was popularized in 1905, with the release of the book "Jokes and their Relation to the Unconscious” by Sigmund Freud.
Hungarian-British author and journalist Arthur Koestler's incongruity theory describes the two simultaneous rival logics that exist in jokes as the source of their humour. This combinatorial relationship is termed "bisociation." A punch line is the word, concept or situation that bisociates the incongruous elements of a joke. The novel link of juxtaposing ideas disturbs the thought and emotions of the listener, resulting in a humored reaction. For example, the joke “I want a job cleaning mirrors, it’s something I could really see myself doing” involves two competing meanings of the phrase “see myself doing.”
