As of this latest episode, Kurtwood Smith and Debra Jo Rupp are the only actors to appear in each and every episode of 'That '70s show/That '90s show' franchise.
The title is named after the Kim Wilde song of the same name that originally came out in the '80s. A rendition by The Muffs, whose song "Sad Tomorrow" previously appeared in That '90s Pilot (2023), was featured in Clueless (1995) that came out alongside Free Willy 2: The Adventure Home (1995) on Leia's 15th birthday. In addition, the latter film is a sequel to her favorite film Free Willy (1993). Another song from Clueless That '90s Show's first season featured was Salt-N-Pepa's "Shoop" which can be heard when Leia successfully kissed a boy in Lip Smackers (2023).
