To be fair, most sitcoms are forgettable. I watched Family Matters, Hanging With Mr Cooper, Step By Step, SThe Smart Guy, Sister Sister, Sparks, the Wayans Brothers, Malcolm, and Eddie, Moesha, Girlfriends;etc religiously and can't remember SHIT about any of them. And that's just the 90's. Can any of you remember shit about Amen or The Jeffersons? I can't at all.
The only 90's sitcoms with laugh tracks worth remembering Imo are Seinfeld, Fresh Prince, Martin, Living Single, A Different World, and maybe Boy Meets World and My Brother and Me.
