We have Kurtwood Smith and Debra Jo Rupp, who reprise their roles of Red and Kitty Forman, respectively, to thank for this major Easter egg reveal. "Different furniture in the in the basement," Kurtwood shared to E! News when asked about callbacks, "which we come to realize was, during the '70s Show, the living room furniture that has just been sent to the basement."
While That '90s Show may be about a new youthful gang, the OG stars—including Topher Grace, Ashton Kutcher, Mila Kunis, Wilmer Valderrama and Laura Prepon—all reprise their respective roles from That '70s Show.
Don Stark, who played Donna's dad Bob Pinciotti, and Tommy Chong, who played Leo, the hippie owner of Foto Hut, also have cameos on That '90s Show.
Leia Forman (Callie Haverda) is an Easter egg in her own right, as it highlights what a huge Star Wars fan her father, Eric Forman (Topher Grace), is.
Leia's new BFF Gwen (Ashley Aufderheide) doesn't just live next door—where her mom Donna Forman (née Pinciotti) grew up—the teen lives in her old bedroom.
That '90s Show proved that the water tower is still the go-to spot for Point Place teens to party. You may fondly remember the water tower as the spot where Ashton Kutcher's Kelso fell while doing some graffiti.
It may be a new decade, but the iconic weed circle is still happening in the Forman basement. After Leia and her friends discover Eric and Hyde's secret stash, the next generation of Point Place teens consume some cannabis.
During episode six, titled "The Birthday Girl," Red refuses to be outdone by fellow grandpa Bob. And so, he gifts Leia Eric's old car: the Vista Cruiser.
"This has to go," a tearful Kitty notes while cleaning up the basement. "We don't have a dog anymore."
What may seem like a throwaway line is actually very telling for fans of Schatzi, Kitty's beloved dog. Looks like the dachshund didn't make it into the '90s.
Not only is it revealed that Jay (Mace Coronel) is Michael Kelso's son, but the teen has carried on his father's legacy. In addition to being a ladies' man, Jay utters his dad's catchphrase—"Burn!"—in episode 10.
On the audience's reaction to the return of "burn," Mace told E! News, "I genuinely wasn't expecting to really throw back to any lines that Ashton said in the original. And I didn't think about it—it just really just came out fluidly."
