What's a librarian's favorite bait?

This joke reels you in with a classic bit of wordplay, all centered around a librarian's unique "bait (Review)." The humor hinges on the delightful double meaning of "bookworms." Initially, your mind might go to the literal creepy crawlies that munch on pages – a librarian's worst nightmare, certainly not something they'd use to attract anything good!

But then comes the clever twist. A "bookworm" also describes someone who absolutely devours books, an avid reader. For a librarian, whose mission is to connect people with stories and knowledge, attracting these human bookworms is precisely their goal. So, while actual book-eating insects are a historical menace to libraries (and still a concern for rare collections), the joke playfully flips the script, making the *human* kind of bookworm the most desirable catch. It's a charming nod to the love of reading and the folks who help us find our next literary adventure.
