example, the statement "π is only half a pie." (π radians is 180 degrees, or half a circle, and a pie is a complete circle). Another example is "Infinity is not in finity", which means infinity is not in finite range. Another example is "a Freudian slip is when you say one thing but mean your mother." The recursive pun "Immanuel doesn't pun, he Kant", is attributed to Oscar Wilde. Visual Visual puns are sometimes used in logos, emblems, insignia, and other graphic symbols, in which one or more of the pun aspects is replaced by a picture. In European heraldry, this technique is called canting arms. Visual and other puns and word games are also common in Dutch gable stones as well as in some cartoons, such as Lost Consonants and The Far Side. Another type of visual pun exists in languages that use non-phonetic writing. For example, in Chinese, a pun may be based on a similarity in shape of the written character, despite a complete lack of phonetic similarity in the words punned upon. Mark Elvin describes how this "peculiarly Chinese form of visual punning involved comparing written characters to objects." Visual puns on the bearer's name are used extensively as forms of heraldic expression, they are called canting arms. They have been used for centuries across Europe and have even been used recently by members of the British royal family, such as on the arms of Queen Elizabeth The Queen Mother and of Princess Beatrice of York. The arms of U.S. Presidents Theodore Roosevelt and Dwight D. Eisenhower are also canting. In the context of non-phonetic texts, 4 Pics 1 Word, is an example of visual paronomasia where the players are supposed to identify the word in common from the set of four images. Other Richard J. Alexander notes two additional forms that puns may take: graphological (sometimes called visual) puns, such as concrete poetry; and morphological puns, such as portmanteaux. Use Comedy and jokes Puns are a common source of humour in jokes and comedy shows. They are often used in the punch line of a joke, where they typically give a humorous meaning to a rather perplexing story. These are also known as feghoots. The following example comes from the movie Master and Commander: The Far Side of the World, though the punchline stems from far older Vaudeville roots. The final line puns on
