Like taking sailing advice from the captain of the Titanic

Quote: "Not even God could sink this ship,"  [Commonly attributed to Captain Edward John Smith of the Titanic]. In the outstanding movie "The Dark Knight", the Joker, played by Heath Ledger, was holding Batman's girlfriend outside the window of a skyscraper. Batman instinctively said, "Let her go." And the Joker responded with the perfect phrase that someone probably should have pointed out to the captain of the Titanic when he claimed that 'even God could not sink this ship'.  The Joker's wisdom?  "Very poor choice of words!"
