I just thought I would start a thread about TV characters who have love to hate relationships on their respected shows.
So far one of my favorites is Odo and Quark on Star Trek DS9, as its fun to watch those two interact together on show episodes.
Second, is The Ropers from the late 70's sitcom Threes Company and later on their own show called the Ropers. They had the perfect love to hate married relationship with Roper's stinginess and lack of romantic interest in his wife, who loved to point out all his faults and nag him to death making the two compatible in every sense for television sitcom relationships.
What are your favorite(s) character couples or duos that love to hate one another?
