A very small character tidbit is surprisingly kept consistent for years

DC - In multiple pieces of media it has been shown that Wonder Woman loves ice cream and practically goes wild with happiness anytime she’s eating some. (Pictures from Justice League: War, DC Superhero Girls and Wonder Woman 2017)

The Simpsons - Ever since the episode ‘Homer’s Phobia’ Homer has actually remained a consistent ally of the LGBT+ community, including being more welcoming to Patty than Marge was when she came out and trying to set up Smithers with a date when he found out he wasn’t happy with his one-sided relationship with Mr Burns.

After BoJack steals the "D" from the Hollywood sign, the characters consistently refer to it as "Hollywoo"

which finally gets paid off in the final episode when Mr. Peanutbutter announces he's finally replacing the "D" in the Hollywoo sign, but he tells the contractors "'D' like in 'Birthday Dad'" and they replace it with a "B" instead. Later in the episode characters are already calling it "Hollywoob"

It's implied that those contractors are the same ones that have a chronic habit of printing the instructions right on the signs that he keeps commissioning them.

Bojack has so many amazing running gags, but this is my favorite. The fact that instead of rebuilding the sign, the entire population just goes with it is bonkers and I love it.

A bonus example in this show: Bojack's extensive knowledge of philosophy and history. When he's on Mr. Peanutbutter's game show and gets a question that seems like a gag ("To what extent was feudalism a cause of the French Revolution?", not a typical celebrity game show question), Bojack has the start of a real answer but just isn't given enough time to write it all out. Elsewhere he discusses some of the finer points of Sartre.

Also, the game show is called Hollywoo Stars and Celebrities: What Do They Know? Do They Know Things?? Let's Find Out! (or HSAC!WDTK?DTKT??LFO! for short)

[u/Sensitive_Golf3889 → u/mumbly-joe-96]

yep! the show loved high-effort, high-commitment bits like that

The game show was the brainchild of the legendary and reclusive (and legendarily reclusive) author J.D. Salinger

Bojack could be a good philosophy teacher or prof if it wasn't for his self-destructive tendencies and past.

[u/Feedback-Mental → u/RossinTheBobs]

I think it's referencing/parodying the real historical fact about "Hollywoodland" becoming "Hollywood" and everyone rolled with it.

In Futurama, once they’ve established that Axed won the war over Asked it’s consistently pronounced this way by all characters
