A quote from an old text book:

"The variety of foreign bodies which have found their way into the rectum is hardly less remarkable than the ingenuity displayed in their removal.

A turnip has been delivered per rectum by the use of obstetric forceps.

A stick firmly impacted has been withdrawn by inserting a gimlet into its lower end.

A tumbler, mouth downwards, has several times been extracted by filling the interior with a wet plaster of paris bandage, leaving the end of the bandage extrusing, and allowing the plaster to set."

Bailey and Love 1943, A Short Practice of Surgery.
