A magician was working on a cruise ship in the Caribbean.  The audience
would be different each week, so the magician allowed himself to do the same
tricks over and over again.
     There was only one problem:  The captain's parrot saw the shows each
week and began to understand how the magician did every trick.  Once he
understood he started shouting in the middle of the show:
     "Look, it's not the same hat"
     "Look, he is hiding the flowers under the table"
     "Hey, why are all the cards the Ace of Spades ?"
     The magician was furious but couldn't do anything; it was, after all,
the captain's parrot.
     One day the ship had an accident and sank.  The magician found himself
on a piece of wood in the middle of the ocean with the parrot, of course.
     They stared at each other with hatred, but did not utter a word.  This
went on for a day and another and another.
     After a week the parrot said:  "OK, I give up.  Where's the boat?"
