puns in serious or "seemingly inappropriate" scenes, like when a dying Mercutio quips "Ask for me tomorrow, and you shall find me a grave man" in Romeo and Juliet. Shakespeare was also noted for his frequent play with less serious puns, the "quibbles" of the sort that made Samuel Johnson complain, "A quibble is to Shakespeare what luminous vapours are to the traveller! He follows it to all adventures; it is sure to lead him out of his way, sure to engulf him in the mire. It has some malignant power over his mind, and its fascinations are irresistible." Elsewhere, Johnson disparagingly referred to punning as the lowest form of humour. Rhetoric Puns can function as a rhetorical device, where the pun serves as a persuasive instrument for an author or speaker. Although puns are sometimes perceived as trite or silly, if used responsibly a pun "can be an effective communication tool in a variety of situations and forms".

Many restaurant and shop names use puns: Cane & Able mobility healthcare, Sam & Ella's Chicken Palace, Tiecoon tie shop, Planet of the Grapes wine and spirits, Curl Up and Dye hair salon, as do books such as Pies and Prejudice, webcomics like (YU+ME: dream) and feature films such as (Good Will Hunting). The Japanese anime Speed Racer's original Japanese title, Mach GoGoGo! refers to the English word itself, the Japanese word for five (the Mach Five's car number), and the name of the show's main character, Go Mifune. This is also an example of a multilingual pun, full understanding of which requires knowledge of more than one language on the part of the listener. Names of fictional characters also often carry puns, such as Satoshi's English name, Ash Ketchum and Goku ("Kakarrot"), the protagonists of the anime series based on the video game series Pokémon and the manga series Dragon Ball, respectively, both franchises that are known for including second meanings in the names of many of their characters.
