All three of these were wonderful. In the first, that criminal goes to the electric chair for producing second hand smoke. Homer gets his hairpiece after he dies, but it begins to invade his brain and cause him to commit murder. His first two victims are Apu and Moe. Part 2 sends Bart and Lisa into an Itchy and Scratchy TV show where they are victimized by the dog and cat. The third is the best when it is revealed that Marge was impregnated by one of those one eyed aliens. The best line in the episode comes when Home answers the door. Don't miss it.
