Staff at the University of Liverpool Library were stunned to discover a rotting slice of processed cheese being used as a bookmark, sparking much amusement and revulsion on Twitter.
A disgusted staff member tweeted a photo of the cheese with a simple piece of advice to students: “This is not a bookmark.”
The tweet quickly racked up an un-brie-lievable amount of likes as users shared their own stories of similarly odd library bookmark finds — including slices of buttered bread, sandwich wrappers, raw bacon and even a wad of cash (although that one was probably a mistake).
