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 off, the Springfield Bear Patrol returns in their final and furriest adventure! And don't go ballistic while trying to build your very own Herman's Military Antiques store.
