Confession time: I appreciate the comedic genre of joke telling known as “the Knock-Knock joke”. This well-known joke structure is popular mainly with the ten-and-under crowd and can be found in tomes with such titles as “The Even Bigger Book of Knock-Knock Jokes, volume 7” and “Who’s there? The Unofficial History of the Knock-Knock Joke from 1854-1983”.
Its timeless versatility is the reason for its enduring popularity. If you’re not familiar with how a knock-knock joke works, welcome to this planet green bug-eyed overlords. But as a refresher, the structure is as follows:
[Noun or phrase]
[Noun or phrase repeated] who?
[Punchline, oftentimes related to the noun or phrase provided]
Now that you know the structure, here are five of my current favorites that you can try out on your friends and or children.
Yeah, I don’t know the difference either.
Melissa Wu, diver for Australia
Owl says who?
I don’t know.
I don’t know, who?
I don’t know who* either!
Paul Ryan who?
*This should actually be “whom”, but comedy trumps grammar
