The zoo's inflatable rubber elephant
A provincial zoo director, eager to show economy to his superiors, replaces a real elephant with a rubber one. Two keepers, tired of inflating it by mouth, fill it with gas instead, and it is displayed beside a placard declaring the elephant exceptionally heavy. When a teacher brings schoolchildren to see it, a breeze lifts the elephant over the zoo until it bursts on a cactus, and the children later neglect their studies, turn to drink and vandalism, and no longer believe in elephants.
