The joke “What do you call birds that stick together? Vel-crows!” is another example of a pun, where the humor arises from the play on words. This joke blends “Velcro,” a well-known brand of hook-and-loop fastener known for its sticking properties, with “crows,” a type of bird. The humor comes from the clever manipulation of the word “Velcro” to sound like “vel-crows,” suggesting an amusing and imaginary scenario where crows have the ability to stick together like Velcro. This creates a whimsical image of crows behaving in a manner that defies their natural behavior, sticking to each other as Velcro does.

It’s funny because jokes about eating crayons are occasionally made by Marines as well. Much of it stems from the tasks that Marines are frequently assigned, which call for the ardent destruction of property and the people who protect it in a manner similar to a toddler destroying a room—and the fact that Marines are exceptionally skilled at this.
In addition, a great deal of the duties assigned to the Marines are rather simple tasks. When people from other services refer to Marines as crayon-eaters, they usually mean that they behave like that destructive kid again—that is, they do stupid things with great passion.

The joke “We all know Marines eat crayons, but what’s their favorite flavor of crayon? Crayonberry” plays on a stereotype and wordplay for comedic effect. Firstly, there’s a humorous stereotype or running joke suggesting that Marines, known for their toughness and no-nonsense attitude, are so straightforward that they would eat crayons, an item typically associated with children and non-edibility. This stereotype is used here for light-hearted humor, not to be taken seriously.
The punchline “Crayonberry” is a play on words, combining “crayon” and “cranberry.” Cranberries are a common fruit flavor, and by blending it with the word “crayon,” it humorously suggests that if Marines were to have a favorite crayon flavor, it would be something akin to a real fruit flavor, but still within the realm of crayons.

The joke “What did one potato chip say to the other? ‘Shall we go for a dip?’” employs a pun, a type of wordplay where a word or phrase has a double meaning, creating humor. The term “dip” in this context has two meanings. Firstly, it refers to a sauce or creamy mixture into which snacks like potato chips are often dipped before eating, enhancing their flavor. Secondly, “dip” can mean to go for a brief swim or plunge into water. The humor lies in the dual interpretation of “dip.” In the literal sense, potato chips can’t swim, but they are commonly paired with dips like salsa or guacamole.

The joke “What do you call a potato who reads the news? A commen-tater!” is another example of a pun, which is a form of wordplay that exploits multiple meanings of a term or similar-sounding words for humorous or rhetorical effect. Here, the joke merges “commentator,” a person who discusses news or events, usually on television or radio, with “tater,” a casual slang term for a potato. The humor lies in imagining a potato, an inanimate object, taking on the role of a news commentator. This blend of an ordinary vegetable and a professional role creates a funny and absurd mental image, playing on the similarity in sound between “commentator” and “commen-tater.”

The joke “What did the brown cow say to the brown chicken? Brown chicken brown cow” is a play on sounds, specifically a phonetic pun that mimics the rhythm and sound of a well-known musical phrase from classic guitar-based p*rnography soundtracks, often spelled out as “bow-chicka-wow-wow.” This phrase is associated with the portrayal of sexual situations in ’70s and ’80s films. The humor comes from the innocent set-up involving farm animals which leads to an unexpected punchline that evokes adult themes without stating them explicitly.
