/  It seems there's this magician working \
| one of the luxury cruise ships for a    |
| few years. He doesn't have to change    |
| his routines much as the audiences      |
| change over fairly often, and he's got  |
| a good life. The only problem is the    |
| ship's parrot, who perches in the hall  |
| and watches him night after night, year |
| after year. Finally, the parrot figures |
| out how almost every trick works and    |
| starts giving it away for the audience. |
| For example, when the magician makes a  |
| bouquet of flowers disappear, the       |
| parrot squawks "Behind his back! Behind |
| his back!" Well, the magician is really |
| annoyed at this, but there's not much   |
| he can do about it as the parrot is a   |
| ship's mascot and very popular with the |
| passengers.                             |
|                                         |
| One night, the ship strikes some        |
| floating debris, and sinks without a    |
| trace. Almost everyone aboard was lost, |
| except for the magician and the parrot. |
| For three days and nights they just     |
| drift, with the magician clinging to    |
| one end of a piece of driftwood and the |
| parrot perched on the other end. As the |
| sun rises on the morning of the fourth  |
| day, the parrot walks over to the       |
| magician's end of the log. With obvious |
| disgust in his voice, he snaps "OK, you |
| win, I give up. Where did you hide the  |
\ ship?"                                  /
