1. Before the big twist was revealed in Season 1 – that the characters were really in the Bad Place – the color red was avoided in all set designs and costumes in order to avoid any unintentional connections with the devil/hell.
2. In the real Good Place, Eleanor and Chidi's home is the same as the one they lived in in the Bad Place in Season 1, with some significant changes.
3. There are a lot of subtle nines in the first season, which viewers believe is a nod to the nine circles of hell.
4. The number 322, which appears throughout the series and is the the number of inhabitants of the original neighbourhood, wasn't chosen at random – it's a reference to the insignia of Yale's Skull and Bones society.
5. Bad Janet's outfit was inspired by Sandy's post-makeover look in Grease.
6. The set design across the board featured incredible attention to detail – for instance, all of Chidi's notes were authentic, fact-checked by philosophy advisors the show worked with.
7. During Eleanor's death scene, there's an advertisement featuring Tahani's sister/arch-nemesis Kamilah in the background.
8. In the grocery store sequence, we see Tahani herself gracing the cover of a magazine.
9. Tahani really does have some supreme celebrity contacts in her phone.
10. It's very hard to make out, but if you look closely at Jason's notebook during Chidi's philosophy class, you can see he's written "history of Phil and Sophie."
11. Eleanor's search history is very revealing (and, dare I say, relatable).
12. And here's a closer look at some of the data Michael has on Eleanor.
13. The Good Place is rife with nods to creator Michael Schur's other sitcom Parks and Recreation – a notable one being the Swanson Safe that Jason dies in.
14. Meanwhile there's a nod to The Office and Michael Scott's "World's Best Boss" mug in the scene at the accountant's office.
15. The existence of Larry Hemsworth was foreshadowed before he actually appeared on the show – on the cover of a gossip magazine Eleanor is reading.
16. The restaurants and shops in The Good Place always featured great puns, but the set designers really went to town during the Australian portion of the show – with the name of the coffee cart a particular highlight.
17. And the character names during the Australian segment of the show were also particularly...creative.
18. Janet and Jason got married in the top of the "e" in Bearimy.
19. A tiny Trevor can be seen flying through the background of scenes in the void near the door to Earth after the Judge threw him in there.
20. At the party thrown for the cockroaches in the real Good Place, Eleanor's fave margarita mix – the one she literally died for, Lonely Gal Margarita Mix for One – is seen on one of the tables.
21. The peacock bow tie Michael gave to Tahani in the series finale is the one we see him wearing in the opening scene of the pilot episode in Season 1.
22. And finally, the apartment building Michael lives in as a human is number 12358 – part of the Fibonacci sequence, and also the name of the neighbourhood he built in Season 1. Meanwhile, the building's name, Blatta, is a form of cockroach.
