"Weary" William, who is hungry and obsessed with a desire to make some easy money, hits upon a really excellent idea. The inspiration comes when he finds a stray pup, which appears to be in about the same fix as he, hungry and homeless. "Weary" appropriates the dog and plans his campaign. He finds that he needs more dogs, a bunch of dog collars and a sign. After he has corralled a score or more of canines with collars, each bearing the name "Rover," he gets busy with a sign which reads to the effect: "$100 reward for the return of my pet dog, bearing collar with the name 'Rover.' Mrs. Dogonyon, 22 Stung Street." The sign is posted, and "Weary" lingers close by to await developments. Things start immediately. A copper wanders by and reads the sign with interest. The hobo, unfearful, hurries back to his corral, selects a canine, and hurries back to the copper's beat. The limb of the law is easily roped in, pays five dollars for the dog, and hurries off to claim the reward. "Weary" repeats his little game with a dozen or more pedestrians, among whom are a bevy of pretty girls, a baker, a banker, a sport with a tennis racquet, and a wandering Jew. When he has sold out he resolves to go around to 22 Stung Street and watch the fun. It is not long before the crowd arrives, scores of them, each dragging a pup and each confident of receiving the reward. Imagine the crowd's dismay when they find that 22 is the number of an empty house! The finish of the film is fast and furious, when the hungry bull pup, purchased by the Jew, catches him by the seat of the trousers and refuses to let go.
