Micheal J. Pollard was cast as Mooney's son because Eddie Applegate (who previously had played him) was now busy on The Patty Duke Show; Pollard was only used this one time.
Ted Mooney: (to Chris) I can't get married til I get more customers on my paper route.
Chris: We both like the same Hootenanny singers, we both wear Beethoven sweatshirts, and and we both do our homework listening to Dave Brubeck's Jazz Combo.
Hootenanny was a music series that aired on ABC for a year (1963-1964) during the height of the folk music craze. It taped performances at college campuses around the USA. Dave Brubeck is a jazz musician best known for his recording "Take Five."
