The stone soup story:
"Many years ago three soldiers, hungry and weary of battle, came upon a small village. The villagers, suffering a meager harvest and the many years of war, quickly hid what little they had to eat and met the three at the village square, wringing their hands and bemoaning the lack of anything to eat. The soldiers spoke quietly among themselves and the first soldier then turned to the village elders. "Your tired fields have left you nothing to share, so we will share what little we have: the secret of how to make soup from stones." Naturally the villagers were intrigued and soon a fire was put to the town's greatest kettle as the soldiers dropped in three smooth stones. "Now this will be a fine soup", said the second soldier; "but a pinch of salt and some parsley would make it wonderful!" Up jumped a villager, crying "What luck! I've just remembered where some's been left!"
