Sister, Sister (1994) : 3x9

Lisa and Terrence were going to take Tia to a time share in Hawaii for Thanksgiving, but since their break up things are different. Lisa thinks Terrence won't go, and Terrence thinks Lisa won't go. Of course, they both do go. Lisa invites Ray and Tamera to join them for a family Thanksgiving while Terrence invites Tonya, Ray's ex-girlfriend. When they all show up at the condo, chaos ensues. A traditional Thanksgiving this is not. The twins decide to slip out and explore the island, only to find themselves on a sail boat drifting out to sea. John Ratzenberger guest stars as ""Gus"" the transplanted islander/handyman of the condo complex.
