Railway agent Mike Flannery wants to charge the livestock rate for a shipment of two
guinea pigs and refuses to accept the lower pet rate, saying "pigs is pigs." Flannery believes that the "
guinea" is an indication of the pigs' national origin. He argues that they should bear the higher freight charge of 30¢ for livestock, rather than the lower 25¢ for domestic pets. In support of this, he submits that if they were "dago pigs" or "Irish pigs," there would be no question of the animals' status. Because the customer refuses to accept delivery, Flannery is forced to feed and house what he now calls the "dago pigs" in his office. When he eventually receives instructions to accept the lower price, he discovers that the customer has moved. He is then instructed by his superiors to return the pigs to the company warehouse. By this time, the guinea pigs have reproduced exponentially in Flannery's station house. After returning all the descendants, Flannery resolves to charge the lower rate for any future livestock. ==Adaptations==
