Extremely Overdue Library Book

A character goes to the library and checks out a book. However, they are very bad at keeping track of things, and they lose the book. Months, sometimes years later, they find the book again. The character most likely has to pay hundreds, if not thousands, of dollars in fines. Or rather, he's afraid that he'd have to.

Often a comedic Trope, it's similar to a Mattress Tag Gag in terms of severity, and can often be due to a Scary Librarian in charge of the library. Will often lead to An Aesop (as in, "don't be afraid of frivolous things") or in more whimsical settings, show how petty the bureaurocry can be.

This happens a lot in Real Life. Occasionally the story of a book due 50+ years will be added as a filler in news segments. More often than not, the library will waive the fee as the book is now decades old and can be quite historical. More recently, library fines are capped at a fixed fine (either enough to buy a replacement copy or a set time period after which the fine will stop increasing) so the fine will not break the bank of the poor old man who finds it later in life. Because of this, this trope might be a Dead Horse Trope in the future.

 * In an Arthur episode, "Unfinished". Arthur looked for a new copy of a long-out-of-print book called "93 Million Miles in a Balloon" when the last few pages of his copy of the book are missing (and later revealed to have been in the pocket of his jacket and ruined in the wash). He finds out that the Elwood City Library did have a copy of the book, but it was checked out ten years ago and never returned, as whoever last borrowed it moved out and left no forwarding address. Ms. Turner vowed that if that man ever returns to the Elwood City Library, she will personally revoke his library card.
