Homer discovers the wonders of sushi, trying a piece of every fish on the menu of the Happy Sumo restaurant. But when he eats a bad piece of blowfish, he is poisoned and given 24 hours to live by Dr. Hibbert. With one day left on earth, Homer makes a list of everything he ever wanted to do but didn't and tries to pack it all in before he succumbs to the blowfish poison. After staying up all night, Homer survives and goes on to live his life exactly as he did before--watching TV and eating salty treats.
