Fred overhears portions of a conversation that Wilma and Betty have about taking in a little visitor and stranger and Fred thinks Wilma is having a baby. He asks his mother-in-law to stay to help Wilma with the arrival of their baby. But, to Fred's chagrin, the "little visitor" turns out to be the Flintstones' paperboy, Arnold, and one of the sources of much of Fred's anger and frustration.

Fred's rich Uncle Tex is coming for a visit, and to stay on Tex's short list of inheriting his uncle's money, Fred had told Tex that he had a baby boy and named him after his uncle. What to do in a hurry? Barney to the rescue! Another episode where Fred mistakenly thinks Wilma is having a baby – he finds a bootie that Wilma is knitting for Betty's sister's baby at the end of the episode.

Fred wins a contest to go to Hawaii to be on a TV show ("Hawaiian Spy," a topical reference to ABC's Hawaiian Eye). He is given a role as a stunt double for star "Larry Lava", but it's Wilma that turns out to be the big star instead.
