Episode Title:
The Little Stranger.
Episode Description:
Fred overhears portions of a conversation that Wilma and Betty have about taking in a "little visitor" 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.
