13. Little House on the Prairie (NBC)
Well, welcome to the ratings chart, NBC! Because Little House features two of our top TV icons — No. 94 Melissa Gilbert and No. 24 Michael Landon — we won't give you too hard of a time. In this, the fifth season, the Ingalls temporarily move from Walnut Grove to Winoka, then return home with the orphan Albert in tow. Blind Mary (Melissa Sue Anderson) gets married. And Laura (Gilbert) has yet to meet Almanzo (Dean Butler). Darn.
