Fred and Barney learn that local talent is being sought for the Bedrock Bowl's premiere event, a television special starring Ann-Margrock (voiced by Ann-Margret).

Betty and Barney discover a foundling named Bamm-Bamm on their doorstep and become smitten with the child.

Fred forms a barbershop quartet to compete on the ""Hum Along With Herman"" television show, and in the process discovers that Barney is a natural lead tenor. The catch is that Barney can sing only when he's in the bathtub.

Betty and Wilma employ a ""sleep-teaching"" method to try and turn Fred and Barney into perfect spouses. The plan goes awry, and the foursome are ultimately arrested as thieves. After pleading their cases in court, the wives are sentenced by the judge to twenty days of serving their ""victimized spouses"" breakfast in bed.

In a jewelry store to buy a birthday gift for Wilma, Fred and Pebbles unknowingly encounter jewel thief Baffles Gravel, who plants a priceless diamond bracelet on Pebbles. After finding the hot ice, Fred and Wilma try to get it back to the store before Pebbles ""crime"" is discovered.

Fred misconstrues an overheard conversation and enters Pebbles in a beauty contest, only to find out that the contest is for somewhat older ""babes"" instead of ""babies."" Overcoming the resistance of the contest coordinator, Fred enters Pebbles anyway, with surprising results.

Fred and Barney join an exclusive ""fathers club,"" which offers hen-pecked husbands the chance to play poker under the guise of taking their children for afternoon walks. Fred has to do some fancy switching, though, when he rushes home one day with the wrong infant.

Attending a premarital bachelor party for a Lodge buddy, rowdy Fred and Barney start dancing with the chorus girls in a nightclub, unaware that they are being filmed for television's ""Peek-A-Boo Camera."" The boys do everything possible to keep their wives from seeing the show when it airs on television, and almost succeed.

After being robbed without putting up a fight, Fred tries to prove that he is not a coward. Later, while bowling, he recognizes the voice of the robber and bowls him over, thus restoring his male pride.

After stumbling upon an international gathering of scouts during a camping trip, Fred and Barney become the hit of the scout encampment, much to the dismay of Wilma and Betty when the boys visit them later in Bedrock.

After building a new room onto the Flintstone home, Fred and Barney start feuding. Fueling the rift is the fact that Barney cast the deciding vote against Fred for Water Buffalo of the Year, and Barney's discovery that half of Fred's new room is on his property.

Disguising themselves to gain entry into the all-male Water Buffalo Lodge meeting, Wilma and Betty argue that wives should be allowed to attend the meetings. But after going through painful initiation ceremonies as new members, they decide they are better off staying home.

Proud papa Fred shows his home movies of Pebbles to everyone, including two criminals who discover that he has captured them on film. But rather than sit through the films again, the criminals turn themselves in!

Thinking he will be discovered, Fred takes a job wearing a monster costume in a publicity stunt for a new horror movie. He creates the desired effect, frightens the townspeople, and falls into his own monstrous dilemma.

The razing of the Honeyrock Hotel reminds Wilma and Betty of their courtships while working as hotel waitresses, at which time they mistook hellhops Fred and Barney for young millionaires.
