In the largest merger of imaginary assets in corporate history, Internet giant America Online last week acquired media megacorp Time-Warner for an unprecedented $161 billion in pretend money. 'This merger will revolutionize the way invisible amounts of non-existent cash are transferred,' said Steve Case of AOL, a company whose actual revenues are a tiny fraction of its make-believe valuation. In an effort to keep pace with AOL, website blairwitchproject.com is expected to acquire General Motors sometime later this week.
