Knock-knock jokes are humorous one-liners most commonly associated with children. They consist of a lead-in line starting with “knock-knock” and a response beginning with “who’s there?” followed by the punch line. The lead-in is the same for each joke, but the responses and punch lines vary.

Knock-knock jokes are an effective way to build rapport and humor with children, as they’re predictable, relatable, and familiar. They are also an opportunity to reinforce language and communication skills, as they involve a give and take between the joker and their audience.

History of Knock-Knock Jokes

The history of knock-knock jokes dates back to the early 1900s when advertising campaigns using this comedic format appeared in the U.S. For example, one of the first knock-knock jokes was published in a 1928 issue of the Washington Star newspaper: “Knock! Knock! Who’s There? Odessa. Odessa Who? Odessa lots of fun for everyone!”

These jokes were popularized in the 1940s with the introduction of the “Knock-Knock” book series by author S.T. Adams. The books featured a collection of silly one-liners and were aimed at children aged 4 to 8. From then on, knock-knock jokes were a staple in American culture and found their way into television shows, movies, and even into the homes of families.

Types of Knock-Knock Jokes

There are several types of knock-knock jokes that can be used to make people laugh. The most common type is the pun-based joke, which involve a play on words. These jokes involve a response and punchline that are related to each other, such as:

Knock Knock!
Who’s there?
Boo
Boo Who?
Don’t cry, it’s only a joke!

Another type of knock-knock joke is the one-liner joke. These jokes are shorter versions of the pun-based jokes and require a clever response. For example:

Knock knock!
Who’s there?
Cow
Cow who?
No, cow say moooo!
