Not all objects are solid. In 1987, a case was documented of a patient who administered a cement enema. After it solidified and impacted, the resulting block had to be surgically extracted. Another extreme case occurred in November 1953. A depressed man inserted a 15 cm long cardboard tube into his rectum and tossed a lighted firecracker into the tube's opening, resulting in a large hole in his rectum.
