“Homer Simpson in: ‘Kidney Trouble’” – Season 10, Episode 8

On paper, this should have been a classic. A season 10 episode written by legendary Simpsons writer John Swartzwelder focused on Homer and his dad’s relationship sounds fantastic.
But sadly, Homer is too much of a jerk in this episode, essentially leaving his dad to die twice(!) and never really earning its ending. The Ship of Lost Souls is a fun bit, and the ghost town opening segment is solid, but the rest never works and you end up rooting against Homer by the end.
