The Donaldsons, as the next-door neighbors, made their first appearance in the series earlier in the season in New Neighbors (1957). In that episode, Mr. Donaldson is played by Charles H. Gray and Mrs. Donaldson by Phyllis Coates. Here only Mr. Donaldson makes an appearance and is played by Ray Kellogg, who makes another appearance in the series in Stuart Nicolai in season 4, only this time as Mr. Waters, the father of Beaver's friend.
