May We Peel A Twenty Oner?
“Now suppose that a particular Twenty-Oner develops an unexcisable and deadly tumor growing from the outside layer into the eighteenth layer below. The tumor will not go any deeper into the Twenty-Oner’s body, but if left untreated it will eventually fatally disrupt the functions of the whole humanoid body. So the doctors suggest peeling off eighteen layers. This has been done before and is invariably successful. Indeed, peeling off layers is a cosmetic technique widely used among the Twenty-Oners.”
