Synopsis by Hal Erickson
Knowing that Fred is not exactly fond of Arnold the Newsboy, Wilma is a bit nervous about allowing Arnold to stay in the Flintstone house while his mother is out of town. Thus, when broaching the subject to Fred, she makes vague references to a "little stranger" coming to visit. Not surprisingly, Fred jumps to the conclusion that Wilma is pregnant--whereupon he summons his mother-in-law to come to town to help out in Wilma's hour of need. When this episode was rebroadcast in the summer of 1963, a new opening sequence was filmed to "explain" that it takes place before the birth of the Flintstones' baby daughter Pebbles.
