The Devil's Dictionary: Proboscis
The rudimentary organ of an elephant which serves him in place of the knife-and-fork that Evolution has as yet denied him. For purposes of humor it is popularly called a trunk.
Asked how he knew that an elephant was going on a journey, the illustrious Jo. Miller cast a reproachful look upon his tormentor, and answered, absently: "When it is ajar," and threw himself from a high promontory into the sea. Thus perished in his pride the most famous humorist of antiquity, leaving to mankind a heritage of woe! No successor worthy of the title has appeared, though Mr. Edward Bok, of The Ladies' Home Journal, is much respected for the purity and sweetness of his personal character.
