26 details and callbacks to 'That '70s Show' on season 1 of Netflix's spin-off series, 'That '90s Show'

The first scene of "That '90s Show" is set in Point Place, Wisconsin on July 3, 1995, at 11:47 a.m. in Kitty Forman's kitchen.

On the original series, the opening scene took place in Point Place, Wisconsin on May 17, 1976, at 8:47 p.m. in Eric Forman's basement. Later episodes of "That '70s Show" also utilized the title cards.

This is reminiscent of Kitty taking pizza rolls out of the oven while singing along to "Love Will Keep Us Together" by Captain & Tennille in her first scene of "That '70s Show."

On the first episode, Red Forman tells Leia, "I bet you're a holy terror on the basketball court. I hear you got your mom's jump shot and your dad's last name."

This is a nod to Donna's sports skills and Eric's lack thereof.

Now, they're updated to suit the decade.

Leia uses her debate-club skills to negotiate with the owner of the discount-liquor store and obtain a tap.

On the first episode of "That '70s Show," Eric was tasked with stealing beers from the party happening upstairs in the Forman home. When he retrieved the alcohol and brought it to the basement, Steven Hyde proposed a toast to Eric, who called the moment the "proudest day of my life."

The keg tap dilemma in the pilot of "That '90s Show" is also similar to a plot from season one, episode six of "That '70s Show."

On the episode, the gang found a keg on the side of the road and decided to throw a party at a vacant house. But they forgot to bring a tap for the keg, so Kelso went to the liquor store pretending to be 25 years old. Even though he was clearly underage, the clerk didn't care because Kelso had the money for the item.

Eric uses Red's iconic phrase in the series premiere when Leia refuses to leave for space camp with her dad.

He tells his daughter, "You're getting in that car or my foot is getting in your ass!" much to Kitty and Donna's disappointment. Red, however, is pleased and tells Eric: "I have never been prouder."

When Donna finds Eric sitting on top of the hood, he admits that he's struggling with feeling like Leia doesn't need her anymore. The hood was a popular spot where many conversations took place on the original show.

On "That '90s Show," Donna assures Eric that everything will be OK.

"We have our whole lives because your parents gave us the space to find each other," Donna says.

"Really? You lived 20 feet away. I'm pretty sure we would have found each other," Eric replies, prompting her to push his head lightly.

In response, Eric gently pushes Donna's head away.

This was a callback to a scene from the series premiere of "That '70s Show."

On the episode, Eric told Donna that his sister, Laurie, thought they shouldn't be left alone together. Then, Donna pointed out that they were alone at that moment.

"Eric, relax," she added. "We've lived next door to each other forever. You could have had me when I was 4."

"Really? And there I was all day long on the hippity-hop. Stupid! Stupid! Stupid!," Eric said, jokingly knocking his head against the pipe because of the missed opportunity.

Laughing, Donna pushed his forehead on the pipe again, and Eric shoved her head away in response.

On "That '70s Show," Kelso was known for shouting "burn!" when a character delivered a great insult or humiliated someone else.

After Jackie tells Kitty that she and Kelso are getting remarried and are registered at Bloomingdale's, she says, "Let's GO, Michael," emphasizing "go" and using the same bossy tone from the original show.

"Damn, Jackie, will you just give me a minute to enjoy this?" he says to her.

On "That '70s Show," the smoky circle scenes indicated that the characters were high.

On "That '90s Show," Leia and her new friends get high after they discover an old bag of weed in a crate filled with Eric's old stuff.

On "That '90s Show," the helmet can be seen in the background of the Forman basement. In some scenes, the helmet is resting on top of a speaker like on the original series, and in other scenes, it's on top of a dress form.

The headgear, known as the "stupid helmet" on the original series, was a recurring gag. At various points on "That '70s Show," different members of the crew were forced to wear the helmet after saying or doing something stupid.

For example, the guys made Eric wear the helmet after he bought an engagement ring for Donna on season five, episode seven.

Kelso, predictably, wore the helmet the most on the series. Fittingly, he was the last person seen wearing the helmet on the series finale.

Wilmer Valderrama's character says the phrase during a commercial for his salon chain, Chez Fez. In the ad, Fez says that "every day is a good hair day" at his establishment.

"I said, good day," he adds at the end of the commercial.

One of the running jokes of the original show is that fans never learned Fez's home country. At various points on "That '70s Show," he said that he's from an island, in addition to other small details about his culture and customs.

On "That '90s Show," Kitty explains to her neighbor Sherri Runck that Fez was a foreign-exchange student who ended up staying for some unknown reason.

When asked about where Fez is from, the tea kettle whistles, making Kitty's answer inaudible and Fez's home country still unknown.

"I hear it's just lovely there," she tells Sherri.

On the spin-off, Fez is a successful hairdresser with a booming business. This was a natural progression for the character because, on the original show, Fez worked as a shampoo boy at a salon.

Fez holds up a Tootsie Roll during his Chez Fez commercial at the start of episode three. Later, when Kitty stops by his salon, she mentions that he's so successful that he can afford to offer free Tootsie Rolls to patrons.

On the original show, Fez was known for having a candy addiction.

Fez was seen eating a Tootsie Pop, in particular, at the start of season two, episode 24 of "That '70s Show." Then, on the series finale, just as he and Jackie were about to have their first official kiss as a couple, he ruined the moment by laughing because he was "thinking about Tootsie Rolls."

Fez tells Kitty that he and Jackie were at the Hedonism Resort in Jamaica when he caught her on the phone one night, talking to Kelso.

"She left me there," Fez says. "And I spent the next five days getting kicked out of hot tubs for talking too much."

During episode four, Leia and Gwen go to a rave with the others in Milwaukee.

Upon their arrival, Gwen realizes that they forgot Ozzie. Then, the scene cuts to Ozzie screaming with his hands on his cheeks, similar to Macaulay Culkin's famous scene in "Home Alone."

Eric and his friends were often seen at The Hub on "That '70s Show."

On the spin-off, Gwen Runck, Ozzie, and Leia hang there during episode five, when Jay Kelso walks in with a girl named Serena.

On the spin-off, Bob still lives in Florida but visits Wisconsin to celebrate his granddaughter's birthday.

Red gave Eric the car on the series premiere of "That '70s Show."

On episode six of "That '90s Show," Red gifts Leia with the same Vista Cruiser for her 15th birthday and promises to teach her how to drive.

On episode seven of "That '90s Show," Kitty says that Jay is different from his idiotic dad.

"Michael Kelso glued himself to our refrigerator," Red replies. "I think you're setting the bar kinda low."

This is a callback to season seven, episode 12 of "That '70s Show," in which Red recalled going to the kitchen at 6 a.m. and learning that Kelso glued himself to the fridge.

While in the basement, Gwen comments on her half-brother Nate bringing back the "nasty" keg from the Fourth of July.

"I took care of this thing like it's my baby," Nate says, "Till I dropped it down the stairs."

"Just like mom did to you?" Gwen retorts, leading Jay to shout: "Burn!"

During a conversation with Leia in episode 10, Donna says that she and Eric broke up "a lot" when they were younger and "one of those times I dated Jay's uncle, Casey."

On "That '70s Show," Luke Wilson guest-starred as Kelso's older brother on six episodes, particularly in season four, when he and Donna had a short romance.

On the last episode, Fez gets high in the basement with Nikki and Ozzie, where he complains about his nemesis, Fenton, driving a wedge in his relationship with Sherri Runck.

Then he tells Ozzie and Nikki they're no help, adding: "I miss my people."

The scene then cuts to three flashbacks of various characters high on "That '70s Show."

In the first, Eric, Fez, Hyde, Kelso, and Leo pondered God and the meaning of life while high in the basement.

"Maybe this life doesn't even matter, y'know," Eric said. "Maybe we're not even here. Or, no, maybe I'm here, but you're not. Hello?"

In another scene, Jackie got high with the gang for the first time in an effort to act more zen in season two, episode 25.

In the last flashback to season two, episode eight, Kelso berated Eric for not having sex with Donna and instead choosing to cuddle with her.

"You gotta get with her," Kelso said. "I mean, there's nothing more beautiful than when two people fit perfectly like two of these potato..." he said, getting distracted by the stackable chips in his hands.

After the flashbacks, Fez has a moment of clarity and realizes he has to let go of his grudge against Fenton to fix his relationship with Sherri. He also briefly reunites with Donna.
