It's a strange idea to call an artistic figure a "hanging pig." Because you see, if we were to imagine a pig hanging by its hind legs from a pole, we would have a hard time visualizing the grace, lightness, and elegance displayed by trapeze artists. Unless the story tells of a pig once distinguished itself by its acrobatic talents, we would have to consult the Guinness Book of Records on this subject... In any case, we prefer to see pigs having fun in the mud and ballerinas twirling in the air, rather than the other way around!
