The Poison Donut

Homer is at work at the Power Plant, woofing down donuts. Mr. Burns has watched Homer scarf down his valuable donuts for years and has had enough. Later that night, Mr. Burns poisons one of the donuts. The next day, Homer is at it again, eating more donuts, when suddenly his heart stops. He'd eaten the poison one! He collapses to the floor and dies while Mr. Burns is laughing hysterically through the security camera.
