And then there is that less-well-known philosophical puzzle, 'Schroedinger's Soldier'
A soldier is placed in a sealed box. Attached to the box is an apparatus containing an American Pork IMP and Naval Emergency Survival rations. This apparatus is separated from the soldier in such a way that the soldier can in no way interfere with it. The experiment is set up so that there is exactly a 50% chance of the soldier eating either the Pork IMP or the Naval rations. If the IMP is triggered, the soldier eats the IMP, releases a gaseous emission, and suffocates. If the navy ration is triggered, the dead weight of the Naval ration falls and crushed the soldier.
Solution: According to Army mechanics, the soldier waits for the lid to close. Thinking that it is night time, the soldier makes a rope out of his socks, lassoes the IMP, turns the heating element and his water carrier into an IMP bomb, and blows out the side of the box. Grabbing the heavy dead-weight of the Navy ration, the soldier knocks the two observing scientists unconscious, then makes his way off to the nearest pub.
