18 details you might have missed in 'The Good Place' series finale

At the start of the finale episode, Chidi is overseeing a moral philosophy class in the Good Place. Two of his "students" are none other than UCLA professor Pamela Hieronymi and modern philosopher Todd May.

Both Hieronymi and May have been credited consultants for "The Good Place" since its inception, helping shape the show's explanations of moral and ethical philosophy concepts.

As revealed in the episode's credits, actor Nick Offerman (who is a woodworking craftsman in real life) was making that cameo appearance as himself.

Some fans thought he might have been representing his character Ron Swanson from Mike Schur's other NBC comedy series, "Parks and Recreation." In earlier episodes of "The Good Place," there were references to products and names from "Parks and Rec."

But Schur has made it clear that there isn't a literal shared universe between the two shows — only some fun nods through the use of props.

The number 322 has shown up several times throughout the series. The first occurrence was when Michael mentioned that Eleanor's Good Place neighborhood (which was really the Bad Place) contained 322 residents.

"That's a dumb reference to the Skull and Bones thing, that secret society at Yale where for some reason that number is significant to them," Schur told Insider in a recent interview. "So it's just one of those mystical numbers that pops up in a bunch of Reddit threads."

It pops up once again in the series finale when Jeff told Michael he had 322 frog-related trinkets.

When first sitting down to write season one, Schur knew that shows like ABC's "Lost" had used iconic number sequences to imbue extra layers of meaning in scenes. So Schur picked the beginning digits of the Fibonacci sequence (1-2-3-5-8) as the Good Place neighborhood's ID number.

The total number of passing yards in Jason's "perfect" game of Madden was 12358.

When giving a goodbye speech at Jason's end-of-existence party, Pillboi ended by saying Jason was his "Gardner Minshew."

If you're not a football fan, and more specifically a fan of the Jacksonville Jaguars team, you might not have understood that Pillboi was referring to the current quarterback of the Jaguars.

When Jason walks through the final door, ending his existence, he's wearing a bright blue tracksuit with a T-shirt underneath sporting a wave.

Later on in the episode, Chidi tells Eleanor a metaphor about the end of life, equating someone's time alive to the presence of a wave.

"Picture a wave in the ocean," Chidi said. "You can see it, measure it — its height, the way the sunlight refracts when it passes through. It's there and you can see it and you know what it is. It's a wave. And then it crashes on the shore, and it's gone. But the water is still there. The wave was just a different way for the water to be, for a little while."

Having a wave on Jason's shirt is likely a nice allusion to this metaphor.

In season three, the Judge (Maya Rudolph) sent Trevor flying off the walkway into the afterlife void.

"On a number of occasions after that, whenever we would see people walking through the afterlife system on the bridge, we would take the footage we recorded of Adam Scott flying backwards and drop it into the background," Mike Schur told Insider in a recent interview. "We would use his actual scream and put it really delicately in the background."

Many fans probably noticed how the yellow dress Tahani wore in the finale was the exact same costume she wore in the pilot episode.

But a much more subtle costume callback was Michael's bow tie. When Tahani decided to become a Good Place architect, Michael gifted her the peacock-feathered bow tie he was wearing on the very first day Eleanor arrived in the Good Place.

The cast and crew of "The Good Place" really did travel to Greece and France to film scenes for the finale of the series. When location scouting, Schur and the team realized there was a stretch of road that looked very similar to the cobble-stoned street in the fake Good Place neighborhood from seasons one and two.

While in the magical version of Greece that Janet conjured for them, Eleanor and Chidi were snacking on two koulouria (sesame bread rings). Then Janet opened a new door, and they walked into a magical version of Paris, France.

As soon as they stepped through the doors, the koulouria transformed into partially eaten croissants.

This was the second appearance of 322 in "The Good Place" series finale. Once again, this was a nod to the Skull and Bones society number that Mike Schur liked to plant in the show.

During one scene with Michael, the Judge is wearing a T-shirt promoting the East Dillon Lions — the fictional football team in the TV show "Friday Night Lights."

Throughout the show, the Judge made references to the shows and podcasts she was bingeing. "Friday Night Lights" was one of her earlier favorites, so this was a fun callback.

This was a costume choice partially inspired by "The Good Place" actor Marc Evan Jackson, who hosts the show's official podcast. Every time Eleanor wore a striped sweater, Jackson and other fans speculated that it had an important meaning.

For Eleanor's final outfit, the one she wore as she walked through the final door, the costume designers thought the six-striped sweater would be a perfect time to finally fulfill that fan theory.

The six stripes on her sweater are a colorful representation of "Team Cockroach": Eleanor, Chidi, Tahani, Jason, Janet, and Michael.

The store, Murray and Mande's Coffee, has a sign boasting "unnecessarily complicated pourover."

On "The Good Place" podcast, Mike Schur said writers Matt Murray and Joe Mande were the two people in the room who enjoyed making fancy pourover instead of drinking the regular drip coffee from the team's coffeemaker.

Throughout Schur's other shows, the husbands and wives of cast members have appeared for small cameos.

In season two of "The Good Place," Kristen Bell's husband Dax Shepard played one of the Bad Place demons. In "The Office," Steve Carrell's wife, Nancy Carrell, played Michael Scott's realtor and short-time girlfriend, Carol. And lastly, in "Parks and Recreation" Amy Poehler's former husband, Will Arnett, played the MRI technician Dave.

When a stranger comes to return a piece of misdelivered mail to Michael, we see the outside of his apartment building. The number is once again that 1-2-3-5-8 sequence that appears throughout the whole show.

You get a glimpse of Michael's apartment number when he's opening the piece of mail that his down-the-street neighbor returned to him.

The first detail in this letter was Michael's last name of "Realman," which is a hilariously obvious fake name.

Then, in the letter, Michael is told that when he uses his rewards card that the company "will be collecting data on everything you buy and making sure that ads are targeted directly to you for all your needs. Fun!"

It later says that they'll need his email, which will allow them "to find you on Facebook and send you targeted ads there."

Hopefully, Michael's time on Earth doesn't devolve into complete technological chaos when he joins Facebook.
