Fred begins to fret when his wealthy Uncle Tex arrives in Bedrock. In hopes of inheriting his uncle's millions, Fred has allowed Uncle Tex to believe that the Flintstones have a baby son named Little Tex. In desperation, Fred persuades Barney to disguise himself as the mythical infant. 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.
