National Knock Knock Joke Day is on October 31, every year, and it celebrates one of the most popular joke cycles. Perfectly suitable for all age groups, knock-knock jokes are told in many English-speaking countries. Knock-knock is a call-and-response joke that involves an interesting play with words.

History of National Knock Knock Joke Day

We know how it goes… Someone begins the joke by saying, “Knock knock,” followed by “Who’s there?” After they mention a name, the person can reply by asking for a surname or end the joke with a pun that involves an interplay between the words.

The earliest variation of the knock-knock joke can be traced back to the 1900s. According to Merely McEvoy, the joke began around 1900, and it started with the question, “Do you know Arthur?” to which one would naturally ask, “Arthur who?”. The person telling the joke would then reply, “Arthurmometer!”

In 1929, a book called “The Games of Children: Their Origin and History” featured the earliest written form of the knock-knock joke. After the initial “Knock knock. Who’s there?” the joke-teller would reply, “Buff.” Then the audience would typically ask, “What says Buff?” And the final punchline would go, “Buff says Buff to all his men, and I say Buff to you again.” It was popular among children back then, and they enjoyed it very much.

The modern form of the joke was developed in the 1930s. It was introduced into popular culture with the relatable pun that we’re used to today. It goes, “Knock knock. Who’s there? Rufus. Rufus who? Rufus the most important part of your house.” Since humans have been knocking on doors for ages, knock-knock jokes may have a longer history. Nowadays, the joke has become a staple for humor across the world.
