Carly, Jack and the kids are going to her parents' beach house for Thanksgiving in a rented moving truck, since they neglected to make a reservation for a rental car. When they get there they find Carly's mother Kate along with her father Ben--both of whom divorced and married other people years ago. They tell them that they still love their current spouses, but the two of them got back together at Carly's wedding. They all try to have a ""traditional"" Thanksgiving dinner, but Carly is so mad at her folks that she takes Jack and storms off in the truck--temporarily forgetting that they brought the children with them.

After a recap of the Thanksgiving episode, the scene is three months later. Carly's father Ben and his second wife Beverly are visiting, about to celebrate their 25th wedding anniversary. They plan to renew their vows and be remarried by the same judge. Carly has lunch with her mom Kate, who tells her that Beverly invited her to the party. Ben confesses to Jack that he still has amorous thoughts about his first wife. Carly and Jack are afraid lest their parents meet again and rekindle their adulterous relationship of a few months before. Nicole, Will and Sarah buy a silver ring as an anniversary present, then drop it down the elevator shaft.
