Stone Soup

A tactic whereby a character acts in a manner that can be perceived as eccentric or insane, in order to prompt other, bickering, characters into cooperation. This usually happens because of shared concern for the welfare of the first character, or a joint desire to "not upset the crazy person." When it works, it results in An Aesop about cooperation and conflict resolution.

Named for the classic folk tale in which a strange wanderer breezes into town and offers everyone a free bowl of the remarkable stone soup (you know... put the soupstone—a seemingly ordinary rock—into a pot of water, and boil it) he's making—if only they'll help him get a few extra ingredients: potatoes, onions, garlic, carrots, beef, turnips, parsley, salt, pepper, tomatoes, and bread on the side. They do, and are amazed by how good a simple stone can make the water taste. Note that here, the motivation is first curiosity, then quickly greed or, more charitably, merely hunger—since part of the reason they won't cough up food to begin with is that food in the area is scarce. (But once they do, there's enough to feed everyone.)

Compare Fence Painting. Contrast with Too Many Cooks Spoil the Soup.

Comic Books

 * A Walt Disney comic of uncertain vintage once played with this trope by having Gyro Gearloose attempt to make stone soup using "concentrated stone juice".
 * Similarly, in the 1970s Disney book Button Soup, Daisy Duck did this by starting with a single clothing button.
 * In the Archie Comics story "Rock On!" (no longer online?), Jughead makes a "rock hamburger" to lure people away from Reggie's barbecue.
 * Referenced and subverted in Fables. When Jack tries to sell soup stones. Snow White mentions she kept hers, which implies that here, Soup Stones are actually magical.
 * Soup stones are also an alchemical item in Dungeons and Dragons, even coming in different flavours.

Folklore

 * The Russian version of the tale features a particularly bright soldier tricking a miserly landlady to give him ingredients for making a pot of cereal by making "a hand axe cereal".

Film

 * Used in Pirates of the Caribbean: At World's End, as Jack begins rocking the boat, pretending to see something. The others follow, at first out of curiosity, but eventually they catch on.

Literature

 * Possibly inverted in Discworld, where, among bickering, arguing and ignorant nobles, Lord Vetinari has them form committees, telling them to brainstorm solutions. The real reason he does this is to get them all out of the way so he can work out the problem with people who know what they're talking about.
 * Robert A. Heinlein likes the "form a committee to get all the idiots out of the way" version. Lazarus Long does it in the novel Methuselah's Children, as does Professor Bernardo de la Paz in The Moon Is a Harsh Mistress by setting up an Ad-Hoc Congress stocked with all of the blowhard do-nothings.
 * It backfired in The Moon Is a Harsh Mistress when the Congress actually gets work done.
 * The "get rid of the idiots" version also occurs in the backstory of Hitch Hikers Guide to The Galaxy; the Golgafrincham homeworld is threatened by a meteor, so they put all the thinkers on one ship, the doers on another, and the middlemen like hair stylists and phone cleaners on a third...and then send the third away, having made up the meteor story in order to "clear the chaff" from their society.
 * In Aleksander Fredro's fable The Gypsy and The Woman, a gypsy tricks a greedy woman to give him ingredients for making porridge by making "a nail soup".
 * Played with in P Howard's Captain Dirty Fred. The eponymous captain is so universally disliked that people would do anything just to not be on his side. People he agrees with will immediately change their oppinion, people he wants to see dead instantly become loved and supported by everyone, and generally, any time he's around, the most disorganized gangs that were at each other's throats suddenly become best friends and can get almost everything done working together, as long as they do the opposite of what Fred tells them. And of course, every single time they play into his hands, seeing how.

Live Action TV

 * In an episode of Land of the Lost, Rick has had enough of Will and Holly fighting over a trivial issue and pretends to have snapped. By cooking "stone soup" and eliciting their help in finding "a few extra ingredients", the father teaches them what their real priorities ought to be. Later in the episode, he pulls the same trick on the Pakuni leader Taa, though for a different purpose.
 * Little House On the Prairie had a similar episode.
 * The original folk tale was retold on Jim Henson's The Storyteller. However, the usual Aesop is interestingly subverted when.

Real Life

 * Gen. George S. Patton wrote in his memoirs that during the supply crisis caused by his rapid drive across France, some of the units under his command made further advances this way, first getting just enough fuel to make a reconnaissance in force, then deliberately getting involved in fighting that required notable reinforcements and, of course, extra supplies.
