Living Prop: The little boy has no speaking lines in this episode; he is merely a prop that begins the latest high-decibel argument in the Bunker household.
Mama's Baby, Papa's Maybe: The major driver of the plot — a harried nutcase of a woman, Marilyn Sanders, having had a relationship with Mike shortly before he began dating Gloria, drops her son off at the Bunkers, telling Edith that she knew Mike lived there and would now like him to look after "his son".
Papa Wolf: When Marilyn comes to pick up her son and reveals that Mike really isn't the father, Archie is outraged and, after telling her she disrupted the family dynamic, warns her to leave.
Who's Your Daddy?: Although it comes four years after the kid is born.
