Warren Buffett's Annual Letter to Shareholders

      Warren Buffett's annual letter to Berkshire Hathaway
 shareholders, mailed to them today, contains the usual mixture of
 anecdotes, jokes, admissions of mistakes and wisdom.  Buffett says
 that companies looking at takeovers should beware of what sellers
 tell them; to illustrate, he tells this tale.
      A man says to a veterinarian: "Can you help me?  Sometimes
 my horse walks just fine and sometimes he limps."
      Replies the vet: "No problem.  When he's walking fine, sell
 him."
