A side-splitter. Uncle Josh occupies a box at a vaudeville theatre, where a moving picture show is going on. First a dancer appears on the screen. Uncle Josh jumps to the stage and endeavors to make lover to her, but she flits away, and immediately there appears upon the screen the picture of an express train running at sixty miles an hour. Uncle Josh becomes panic-stricken, and fearing to be struck by the train, makes a dash for his box. He is no sooner seated than a country couple appear upon the screen, at a well. Before they pump the pail full of water they indulge in a love-making scene. Uncle Josh thinks he recognizes his own daughter, jumps upon the stage, removes his coat and prepares to chastise the lover, and grabbing the moving picture screen he hauls it down, and to his great surprise finds a kinetoscope operator in the rear. The operator is made furious by Uncle Josh interrupting his show, and grappling with him they roll over and over upon the stage in an exciting encounter.
