In the Series Finale, Mama is trying to calm Naomi down, who freaks out when Vint leaves her to go to work. Mama tells her the story of how great Carl was when their first child was born. Of course she's lying just to make Naomi feel better. She then tells Iola the real story. Seems she had to take the bus to the hospital when Carl refused to come out of the bathroom, as she went into to labor. Bubba, who's trying to make the college Water Polo team, is driving Mama nuts by running up and down the stairs. When Naomi finally goes into labor, after seemingly being pregnant forever, she refuses to go to the hospital until she gets her hot rollers. Vint, who gets home just then, goes to get the car and panics and smashes his pickup into Mama's car, then promptly passes out when Mama tells him to calm down. Bubba (who made the Water Polo team) and Iola show up a little later and hear a baby cry coming from the trailer. As it turns out, Mama had to deliver the baby, and now they need to pick a name for the Harper's newest addition, a beautiful girl. Vint suggests they call it Thelma, but Naomi wants to name it Tiffany. They compromise and name it Tiffany Thelma.
