more of a family-oriented comedy, with Raven-Symoné, Saundra Quarterman (both playing the cousins of Curry’s character Mark Cooper), Marquise Wilson (who recurred as Cooper’s pre-teen neighbor, Tyler Foster, in its first season) and Nell Carter (playing the principal of the high school where Cooper works as a teacher and coach) joining the main cast. (Longtime Miller-Boyett collaborators William Bickley and Michael Warren, who wrote for Perfect Strangers and created Family Matters, Step by Step and Getting By, would later serve as Coopers showrunners for its last three seasons beginning with the 1994–95 season.) Serving as a Spring replacement for Cooper in 1994 and 1995 was Sister, Sister, starring Tia and Tamera Mowry as identical twins adopted at birth to parents with polar-opposite personalities (Tim Reid and Jackeé Harry) who are reunited during a chance encounter at a clothing store. Despite scoring decent ratings over its two seasons on the network (particularly among teenage viewers), ABC canceled Sister, Sister in May 1995, a few weeks after its second season concluded. (It was subsequently picked up by fledgling “netlet” The WB, where it ran for four additional seasons.) Summer months During the first few years of TGIF, the host interstitials varied during the summer months. The regular hosting rotation continued with new segments during the summer of 1990, the final months of the "mice" motif. For the late spring and summer of 1991, ABC decided to relieve the TGIF stars of filming/taping segments from their respective sets. Instead, stars performed voiceovers for "TGIF Trivia", game-like segments made up of episode scenes and multiple-choice questions. The trivia quiz provided "A", "B" and "C" choices of events that the home viewer was supposed to choose from for a supposed "single" correct answer; in reality, all choices were correct in each round, as every scene featured was from an actual episode inclusion. Stars that narrated TGIF Trivia included Heather Locklear (of Going Places), Telma Hopkins (of Family Matters), Jodie Sweetin (of Full House) and Melanie Wilson (of Perfect Strangers). For the late spring and summer of 1992, ABC ran a promotional contest that chose winners from around the country to host TGIF for a week from their own homes. Those that were chosen were instructed to videotape their own segments from home, giving commentary on the shows that would air on the week they were scheduled to be featured.
