First appearance of Brynn Thayer as Leanne McIntyre, Matlock's daughter. Fans of the show debate whether this is supposed to be a second daughter or his only daughter. In season one, Linda Purl played Charlene Matlock, who left to go to work in Philadelphia, PA. She was only rarely mentioned during the intervening seasons. Here, Leanne McIntyre (her married name), was living in Philadelphia, coincidentally, before deciding to return. Some people assume that this is his only daughter, and as some TV shows will do, the character has been changed. Matlock never said he had any other children.
Ben is making spaghetti and meatballs. He and Leanne argue over how much oregano to add to the sauce. In an episode of The Andy Griffith Show (1960) one night when Aunt Bee was away, three different people served Andy spaghetti dinner, each person using a secret ingredient: oregano.
Ben and Leanne argue over whether Arnold the Pig was on Green Acres (1965) (Leanne) or The Beverly Hillbillies (1962) (Ben). This is kind of an inside joke as the old The Andy Griffith Show (1960) was on CBS at same time as those other two shows.
