Not a CIDU, but perhaps(?) related:

Too much?
Mr. Bee and billr send this in: “He’s carrying-the moon? Is that why he’s put out?” and “So Atlas is carrying the Earth, that’s his job. Is he complaining about having to carry the moon too? I thought maybe there would be a Lego brick that he’s stepping on, but nope.”
Daisy
Elementary, My Dear Watson
I understand the Wizard of Oz references, but Holmes? I must be missing some cultural reference.
A Few from Charles Addams
Some are obscure enough to be CIDUs.
This is from 1985, but it’s Orwellian theme is even more relevant today.
Fourth Wall Fun
By one definition, “4th wall comic refers to a comic book where characters become aware of their own fictional existence and address the audience directly. This concept, known as the Fourth Wall, separates the characters from the readers, allowing them to comment on the narrative and its limitations.” By that definition, not all of these fit. In some of these, it’s that the cartoonist lets us acknowledge the cartoonist’s existence, while the characters remain unaware. Is there a separate term that should be used for that?
Batty
Bob Ball sends this in: “Maybe cats in the 12/8 CIDU could have explained it.”
Is there a backstory to these characters that explains the joke?
The Shape of Things to Come?
travelgirl sends this in: “I understand what a catenary is, but have no idea what that has to do with the punchline… guess my retirement years are catching up to me :) “
Mouseover text: “Some tires are marketed as all-shape tires, but if driven in a climate with both inverted catenary falls and triangle falls they wear out really fast.”
What’s the Point?
You don’t have to be Bill Bickel not to understand this cat cartoon.
On a similar theme – perhaps – but NOT a CIDU, is this one:
Saturday Morning OYs – December 6, 2025
Nice to see a comic with heart.
