"One of the entertainers on a cruise ship was a magician.  since the passengers were different each week, the magician always had a new audience.
  So he always did the same tricks.  the captain's parrot, however, was stationed in the performance hall, and observed the magicians tricks week after week.  Being a wise old bird, he eventually figured ouit all the magician's secrets.  Then, irritatingly, he started heckling during the show.  'Hey, why is every card the same?  It's in hi cape pocket!  It's a different rabbit!'  The magician was fuming, but it was the captain's parrot so he couldn't really do anything.
One terrible day, however, the ship had a boiler explosion and sank.  the magician wound up on a small raft in the middle of the Atlantic with, as luck would have it, the captain's parrot.  They glared at each other with visible hatred but didn't say a word.  This went on for several days.  Finally on the tenth day, the parrot couldn't take it any longer.  Exasperated, he said, 'Okay, I give up.  Where's the ship?'"
