Peggy Makes the Big Leagues - S5-E4
Question: Luanne implies that she would date David if she were two years younger. Peggy says that David actually is her age. How? Luanne is not in high school. She has already tried beauty school and now goes to a community college. I would guess that David failed two grades, but this episode is about teachers giving him special treatment and "cutting slack" (because he is a popular football player).
Answer: His current teachers are giving him special treatment, but he could have repeated grades in elementary school or middle school, making him the same age as Luanne now.
