According to sources, an idea thought of Monday has been reported to be so crazy and ill-conceived that it may actually wind up working. 'Without getting too specific,' said Myron Halversham, 53, the idea's creator, 'let's just say that this is the kind of off-the-wall idea that ordinarily you'd immediately reject as ridiculous and insane, and obviously doomed to fail. But upon second thought, it occurred to me that despiteor perhaps even because ofits utter absurdity, this idea may well be successful.' Despite Halversham's tremendous optimism, area nay-sayers are scoffing at the hare-brained scheme.
