History of National Knock-Knock Jokes Day
National Knock-Knock Jokes Day is observed annually on October 31, coinciding with Halloween. The observance celebrates a familiar style of humour built around a simple call-and-response format that typically ends with a pun or wordplay.
The exact origin of the annual observance and the identity of its creator have not been reliably established. However, the history of knock-knock jokes themselves can be traced through older forms of wordplay and comic dialogue.
William Shakespeare is often credited with introducing the phrase “Knock, knock! Who’s there?” through the porter scene in Macbeth. However, research published by the Library of Congress points to an earlier comic example in a play by Ben Jonson. It also cautions that neither playwright can confidently be identified as the inventor of the modern knock-knock joke.
Knock-knock jokes became especially popular in the United States during the 1930s and have remained a familiar form of family-friendly humour. National Knock-Knock Jokes Day offers a lighthearted reason to share old favorites, invent new punchlines, and enjoy a laugh with friends and family.
