"Bart goes to work on the railroad; Homer stretches the boundaries of his mind and tries to color inside the lines; Lisa feels the good vibrations when Karma-Con comes to town; Grampa Simpson tells it like it is, was, or might have been; Pieman and Bartman take on both friends and foes alike; and to top it all off, the Springfield Bear Patrol returns in their final and furriest adventure! - Provided by publisher.
