A magician on a cruise liner had a parrot, who'd seen all the magician's tricks a million times, long ago having figured out how the magician made everything in the act disappear.

The parrot got bored, his owner growing stale and not developing any new tricks that the parrot could figure out. One night in the middle of the magician's performance, the ship hit an iceberg and sank.

Everyone drowned except the magician and the parrot. The magician managed to swim to a piece of wreckage and climb aboard, immediately collapsing from exhaustion.
Soon afterward, the parrot flew to the magician and perched on the edge of the makeshift raft and stared at the magician. And stared. And stared.

For a whole day the magician was unconscious, and all this time the parrot didn't take his eyes off him. Eventually the magician started to stir. Looking up, he saw the parrot, still eyeing him intently, not even blinking.

Another hour goes by, and finally the parrot squawks, "All right, I give up. What did you do with the ship?"
