A magician has been working on a cruise ship

...doing the same act for
many years. The audiences like him,
and they change often enough that he
doesn't have to worry about finding
new tricks. But the captain's parrot
sits in the back row and watches him
night after night, year after year.

After a while, the parrot figures out
how the tricks work and starts giving
the secrets away to the audiences.
When the magician makes a bouquet
of flowers disappear, for instance, the
parrot squawks,"Behind his back!
Behind his back!"
Well, the magician gets really annoyed at this, but he doesn't know what to do, since the parrot belongs to the captain.
One day, the ship springs a leak and sinks. The magician manages to grab hold of a plank of wood and floats on it. The parrot flies over and sits on the
other end. They drift and drift for
three days without speaking. On the
morning of the fourth day, the parrot
looks over at the magician and says,

"Okay, I give up. Where did you hide
the ship?"
