parrots
A magician working on a small cruise ship has been doing the same routines every night for a year or two now. The audiences still appreciate him, as they change over often enough that he doesn’t have to worry about learning new tricks. However, the ship’s parrot sits in the back row of every show and watches him night after night, year after year.
Finally, the parrot figures out how the tricks work and starts giving it away for the audience. When the magician makes a bouquet of flowers disappear, the parrot squawks “Behind his back! Behind his back!”
The magician gets quite annoyed at this, but doesn’t know what to do. As ship’s mascot, it could not be barred from the lounge, even for the duration of his shows.
One day the ship sprang a leak and sank. The magician managed to swim to a plank of wood floating by and grabbed on. Who should be there but the parrot, sitting on the other end of the plank.
“OK, I give up,” says the parrot after a moment. ” Where did you hide the ship?”
