The Huxtables, The Cosby Show
From that very first episode, Cliff Huxtable took a refreshingly no-nonsense approach to parenting. Remember when Theo announced he didn't need good grades because he didn't need to go to college? Remember what his dad said? "That's the dumbest thing I've ever heard in my life! No wonder you get Ds in everything... I'm your father. I brought you in this world and I can take you out."
