The Huxtables plan a party to celebrate Russell and Anna's 49th wedding anniversary. Cliff surprises his parents with a cruise to Europe, but they are reluctant to accept it. They do not want to leave their friends or give up their daily routine. After dinner, the entire family entertains Russell and Anna with a dance/lip synch routine to "Night Time Is the Right Time" by Ray Charles. They also have another surprise birthday gift: a portrait of Russell and Anna as they looked when they first met. The couple is deeply touched. Russell and Anna have a change of heart and decide to leave on the cruise immediately.
