10. The Lannisters (Game Of Thrones, HBO, 2010-Present)

Getting cheated on by your woman is rough. Getting cheated on by your woman when the other man is her brother? Infinitely worse. Welcome to the Jerry Springer-esque world of relationships on Game Of Thrones, at least when it comes to the Lannisters. Unlike the belly shirt-clad chicks whoo grace Jerry's couch, however, Queen Cersei Lannister (Lena Headey) and her brother, Ser Jaime Lannister (Nicolaj Coster-Waldau) are more than desperate to keep their incestuous messing a secret. Catch them in the act and they might just toss you off a building, something that a few of their in-laws-to-be had to learn the hard way.
