“The Greatest Story Ever D’ohed” – Season 21, Episode 16

In 2011 the popular Simpsons fansite, No Homers Club, selected the 50 worst episodes of the show. And at the top of the list was this episode featuring Ned and Homer visiting Jerusalem. I’ll be honest: I don’t think this is the show’s worst episode, but it deserves a spot here for sure.
It’s a mostly unfunny travel episode in which Ned’s uncharacteristically angry and Homer is dumber and meaner than normal as he continues to not appreciate the various religious landmarks they visit. Eventually Homer loses it, thinks he’s a Jesus-like figure, and really, most people probably tap out at this point.
