A blacksmith has many apprentices working for him, and as a reoccurring game, every so week one of them succeeds at forging a key to let loose his pet monkey. The monkey goes wild, throwing stuff and breaking things until the blacksmith finally recages him and puts on a different lock. The ordeal has become costly. The blacksmith scolds the apprintices and makes them do the monkey catching, and puts them to extra work. The apprentices do find the extra work bothersome, yet they continue to pick the locks, releasing the monkey. The blacksmith is at his wit's end. He makes more and more complex locks, but everytime, one of his apprentices succeeds in solving it. The blacksmith asks for your advice. What should he do? He doesn't want to sell his pet monkey, nor does he have another place for it to stay.

Leave the key hanging on a string in front of the cage. The apprentices will no longer pick the lock. (It would no longer take any skill to release the monkey. If someone releases the monkey, it would be without bragging rights, and everyone would just be mad at him because of the extra work now required of them, ending the game and competition to see who could solve the next lock.) ALTERNATIVE: If the apprentices need more then a day to forge a key he could approach the problem like modern cryptography and change the lock more frequently. He shouldn't be in shortage of locks beeing a blacksmith.
