Following their double wedding, sisters Jan and Marcia and their new husbands, Philip and Wally, look for places to live, and find its not so easy. The young couples are aided in their search for houses by the girls' mother, Carol Brady, who is now working as a real estate agent. As luck would have it, all four fall in love with the same house; they come up with an unusual way to solve their financial problems and beat the acute housing shortage all at the same time. However, some of their new neighbors don't appreciate their off-beat lifestyle and call the police.

Guests:
• Barbara Carson (Miss Fritzsinger)

Sharing a house isn't easy, as the young couples find out. Often their lifestyles clash: toy salesman Wally enjoys bringing his products home, such as a gigantic gorilla that plagues Philip, an often stodgy, academic type. Wally makes friends with Harry, a kid from the other side of the tracks; a robber finds it isn't easy burglarizing the new household; and Jan and Marcia get a lesson in self-defense from their mother, Carol Brady.

Guests:
• Keland Love (Harry)
• Byron Morrow (Professor Thompson)
• Randy Stumpf (Burglar)

Jan and Marcia and their new husbands, Philip and Wally, wind up as contestants on TV's "The Newlywed Game" after the host of the show (Bob Eubanks, guest-starring as himself) has trouble with his car in front of their house and asks to use their phone. When Eubanks suggests the young couples appear as contestants on his show, Marcia, Jan and Wally become excited about the prospects of winning lots of prizes. Philip, however, takes a dim view of the situation, feeling he'll make a fool of himself, but decides to go along with it when he realizes he could win a new aquarium for his guppies. On the show, Eubanks asks the wives questions about their husbands while their mates are backstage; then reverses the situation. The answers turn out to be both amusing and embarrassing.
