Have you ever had to deal with a "white elephant"? Not the actual pachyderm, but what Merriam-Webster calls "a property requiring much care and expense yielding little profit" or, more simply, "something of little or no value." Of course, we're not talking about the sort of "white elephants" you might get in a humorous gift exchange over the holidays, like a tacky t-shirt or an inexplicable kitchen gadget.
