I remember reading somewhere a hungry army came upon some unexpected supplies. All but one of the men filled their packs with things like meats and canned goods. One guy choose instead to carry as much Mustard(!)as he could.

Turns out, the Mustard Man made the wisest selection because for as long it lasted he was able to trade small amounts of mustard for flavoring in exchange for a full dish of whatever meal was being prepared! He turned his one pack full of mustard into many times that amount in meats and other food.
