#13: No Oreos Allowed
Some signs raise more questions than they answer. This library notice declares: “In light of recent events, NO OREOS will be allowed in the library.” Whatever those “recent events” were, they must have involved cookie chaos so severe it warranted an outright Oreo ban.

The mystery is what makes it hilarious. Did someone crumble them into the carpet? Start a double-stuff fight? Or maybe the quiet study space turned into a full-on snack bar. Whatever the backstory, the sign immortalizes it, ensuring Oreos go down as the library’s ultimate forbidden treat.
