For more than 20 years, Mental Floss has proudly served as the home for all things curious and quirky—and 2023 was no exception. Among some of the essential stories we have covered in recent months: IKEA’s gargantuan Swedish meatball, which weighs as much as a Pomeranian and is meant to serve the entire family; 100 facts that will make you say WTF (for example: Al Roker and Lenny Kravitz are distant cousins); and how, in the Middle Ages, an unfortunate mistranslation spawned a misguided mummy-eating fad.

While we published thousands of new stories over the past 12 months, we’re always excited to see any trends that emerge. And in 2023, what we learned is that our readers love to learn about words, phrases, slang, and names—particularly those they might be saying all wrong; which cassette tapes hiding in their attics might be worth a small fortune; the best travel hacks from the people who have tried them all (flight attendants); and anything related to awesomely bad movie(s).

Here are our 25 most popular stories of 2023, in case you missed any of them.
