I did notice that meme; it’s a neat little joke, but if I were cataloguing it, I’d probably place the “Feline Follies” under 590.5, not 99.99, just to keep the taxonomy tidy. As for that 1952 Britannica with the llama illustration, it’s a rare misprint—probably a typesetter error that slipped through the review process. In my little archive I’ve got the original, no llama, so I’ll just note it in the margin and give it a proper place under 300.00 for zoology.

That screenshot would be perfect for the “Mislabeled 1950s” folder—just make sure the llama’s hat is centered and the caption is in Times New Roman, 12-point, just in case someone decides to republish it. And for the book club, I’ve got a classic cat joke: Why did the cat sit on the computer? Because it wanted to keep an eye on the mouse—simple, grammatically sound, and definitely catalog‑worthy.

Glad you’re lining up the llama‑hat screenshot—just check the margins and the pixel density, that’s the only way it looks properly retro. As for a meme‑worthy punchline for the next virtual club, how about this: Why don’t cats play poker in the jungle? Too many cheetahs. Simple, grammatically tidy, and the punchline will land right on the “Cats & Tech” shelf.
