A magician was working on a cruise ship, and the captain had a parrot. The parrot was pretty smart, and after seeing the magic show a few times, it figured out all the tricks and started calling out the secrets and letting the audience in on how the magician was doing them, like "It's up his sleeve" or "there's a mirror under the table".
This went on and on. One evening, the ship suddenly sunk, and the magician and the parrot were the only survivors, sitting in a raft. The parrot, for the first time in a week, was quiet, just sitting there and staring at the magician. Finally, after three days, the parrot said, "Okay. I give up. What did you do with the ship?"
