The sons are the youngest Chip (age around 10), middle Robbie (age around 14), and oldest Robbie (age around 16). This episode is titled "Coincidence" and was first broadcast on April 26, 1962. Steve has some minor problems with his sons. He wishes that he had three girls instead. A little man gives Steve a "good luck coin". Steve walks into a house similar to his where there are three girls with the approximate ages of his sons. The good luck coin is shown with both sides appearing and is portrayed by a token which imitates a Spanish treasure coin.

Steve is at home with two of his three sons and his uncle Bub.

Steve has to drive to a meeting on a Saturday. He sees a little man and offers him a ride. The man introduces himself as Billy Longfellow and gives him an address.

Steve takes Mr. Longfellow to the address and lets him out.

Mr. Longfellow gives Steve a "good luck coin" and leaves. Steve runs into road construction and becomes lost. He ends up at Mr. Longfellow's house. Steve knocks on the door and a little girl answers.

She invites him in.

Steve goes inside and meets Kit and Bobbie Anderson. There is also an older sister Mike and an aunt Mub. The three girls are about the ages of his sons. The little girl asks Steve to fix her hair which he doesn't know how to do. Bobbie wants dating advice for a girl. Steve begins to wonder what is happening to him. Steve returns home and tells what happened.

The sons and uncle don't believe him and ask him if he is tired or overworked. To prove his story Steve takes them to the house.
