Network: ABC/The WB
What are the odds that twin sisters who were separated at birth would wind up meeting 14 years later? That was the premise for Sister, Sister, which starred Tia and Tamera Mowry as Tia Landry and Tamera Campbell. The two couldn't have been more different, but blood is thicker than water. In addition to being polar opposites, the twins were nothing like their adoptive parents, Ray and Lisa. Though at times it seems like the wrong twin ended up with the wrong parent, they eventually became one big family in Ray's suburban Detroit home. It's there that Tia and Tamera were constantly bothered by Roger, who's what Steve Urkel would've been if Steve Urkel looked like Batman from Immature.
After two seasons on ABC, Sister, Sister was cancelled, but The WB scooped it up for the third season. Keeping it in the family, the Mowry twins' little brother Tahj appeared in one episode as T.J. Henderson, the genius from his own sitcom Smart Guy. Sherman Hemsley, of The Jeffersons, played Ray's father and Kid of Kid 'n Play even had a walk-on as one of Tia's bosses. The history of black TV has been well documented by black TV.
