You can run, but you can’t hide… from overdue notices.

Librarians don’t forget—and this shirt proves it. Whether you’re the guardian of the stacks or just a thriller-loving bookworm with a flair for dark humor, the "I Know What You Checked Out Last Summer" tee is your new favorite conversation starter (and low-key warning).

Perfect for spooky season or any time you want to remind folks that the quiet ones are always taking notes. Throw it on for Halloween, summer barbecues, or your next passive-aggressive staff meeting. Pair it with jeans, combat boots, and a barcode scanner for maximum impact.

For the record: Yes, we do remember that you checked out “Twilight” five times.
