A practical joke (commonly called a prank or gag) is a physical trick played on someone to make them look foolish, feel momentary confusion or embarrassment, and provoke laughter among onlookers.
Unlike verbal jokes, riddles, or puns, a practical joke always involves a physical action or setup, such as rigging a Whoopee cushion, short-sheeting a bed, or setting up a hidden-camera gag.
Etymology & Why Is It Called “Practical”?
To modern ears, the adjective practical feels like an awkward fit. We usually use “practical” to contrast with “theoretical” (such as practical application vs. theory). Telling a spoken joke isn’t “theoretical,” so why tag a physical trick as “practical”?
The explanation lies in the 18th-century distinction between verbal wit and physical action:
- 18th-Century “Jokes”: In the 1700s, a “joke” referred almost exclusively to spoken or written wit, a pun, riddle, story, or clever banter.
- “Practical” as Physical Execution: Etymologically derived from the Greek praktikos (“pertaining to action or deeds”), “practical.” In those days, the English word was more tied to it’s Latin roots, meaning “pertaining to action, deeds, or physical execution”. Therefore, the word was used to signify a joke put into physical action rather than merely spoken aloud.
Before “practical joke” caught on in the mid-18th century (first recorded in author Tobias Smollett’s 1751 writings), physical gags were occasionally called “handicraft jokes.” Over time, “practical joke” became the standard polite term in English literature, while colloquial terms like prank, gag, and jape served as everyday synonyms.
“Practical Joke” vs. “Prank”
While the terms are used interchangeably today, subtle stylistic differences remain:
- Practical Joke: The more formal, descriptive literary term emphasizing a physical trick or elaborate setup designed for humor.
- Prank: The older, more informal everyday word (dating back to the 16th century) that carries a slightly wilder or more mischievous connotation.
