These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Fridge Brilliance: According to this episode, Bart's favourite song (or at least one of them) is "Love Stinks". Considering how many relationships he's had over the series and how they have all ended, Negative Continuity or not, is it any surprise?
Dolph, Jimbo, and Kearney singing "Bart Stinks" to the tune of "Love Stinks" by the J. Geils Band.
Lisa telling Bart that his rabbit died — because Homer buried it alive.
Homer and Marge reminiscing about their wedding night, where they made out behind a billboard while a hobo watched them — who turns out to be the same one watching them now.
Moe streaking during the baseball game.
Homer trying to find a chair to rest on in the clothing store.
After Bart's humiliation, Homer reads the sports section of the newspaper with the headline "SHAME!". He turns to the business section with the headline "Boy's Error Weakens Dollar".
Harsher in Hindsight: This episode becomes more depressing after many bullying-related suicides hit the news, specifically what happened to Phoebe Prince.
Heartwarming Moments: Despite this episode being hated for showing Springfield as cruel enough to drive a ten-year-old boy to suicide, the scene of Marge calling the town out for what they've done and arranging a new game to pick up Bart's shattered self-esteem is a bright spot in an otherwise pitch-black episode.
Moral Event Horizon: The townspeople cruelly treat Bart, simply over losing a lousy baseball game and even after Bart tries to commit suicide they don't stop abusing him. They at least apologize to Bart once Marge calls them out on their cruelty. Nonetheless, this is said to be one of the most mean-spirited moments of the series.
Some Anvils Need to Be Dropped: As much as some people hate this episode, it does show that publicly shaming someone over something minor can have an adverse effect on their psychological being.
Tear Jerker: Bart's entire ordeal, especially in light of recent events of kids being bullied and driven to suicide over it.
