Features an early role for Erin Moran. Only 4 years later, she would become a regular cast member on Happy Days (1974).
The wording on Dodie's celebratory cake changes position from one shot to the next.
When the family is gathered around the kitchen table following Dodie's adoption, Ernie tells Dodie, almost in passing, thats he's also adopted. This is the first time Ernie's adoption is mentioned in the five years since he joined the family. Surprisingly, Dodie doesn't seem surprised by the news, and there's no followup dialogue about his adoption.
Although Dodie officially becomes Dodie Douglas in this episode, she had referred to herself as Dodie Douglas in at least one prior episode, and had also been calling Steve "Daddy" for several episodes by this point.
