In Treehouse of Horror II, the Simpsons face three terrifying tales:

The Monkey's Paw: Mr. Burns gifts Homer a monkey's paw that grants wishes. Homer wishes for a turkey sandwich, which appears out of thin air, but quickly rots. Lisa wishes for world peace, leading to an alien invasion. Finally, Bart wishes for a million dollars, which arrives as a tax penalty for "Homicide via Monkey's Paw" after Homer is crushed by a falling piano.

The Bart Zone: Bart develops psychic powers, able to control people and objects with his mind. He uses his powers for pranks, turning Homer into a jack-in-the-box and forcing the family to play endless games. Eventually, Bart's powers become uncontrollable, causing chaos in Springfield. He finally wishes for everything to go back to normal.

If I Only Had a Brain: Mr. Burns removes Homer's brain and places it in a robot body to create the ultimate obedient worker. Homer-bot initially enjoys his newfound strength and lack of pain, but soon misses his family and the simple pleasures of life. He escapes Burns' control and wreaks havoc, eventually returning to his human body.
