An object which is almost totally indistinguishable from a newspaper, the one crucial difference being that it belongs to somebody else and is unaccountably much more interesting that your own - which may otherwise appear to be in all respects identical. Though it is a rule of life that a train or other public place may contain any number of corfes but only one newspaper, it is quite possible to transform your own perfectly ordinary newspaper into a corfe by the simple expedient of letting somebody else read it.
