This unhappily married couple played a central role on the late 70s drama, "Dallas." When they weren't trying to outfox each other, they were outfoxing everyone else -- with varying degrees of success. Turns out J.R.'s "business" trips were actually racy affairs --and he paid the price during a season finale by taking a bullet and leaving the show's followers wondering, "Who shot J.R.?" Sue Ellen wasn't blameless, though. She became pregnant with an apparent heir to the Ewing throne, but her heavy drinking made the rest of us cringe. In a sheer moment of TV magic, her son was born without any ill effects, but that doesn't mean the boy's life was without drama. When the secret was revealed that he might be the son of J.R.'s biggest enemy, viewers waited with bated breath for the inevitable plot twist: Turns out, the boy was actually J.R.'s son. We're willing to bet this news made for interesting dinner table conversation at the Ewing home. It certainly did at ours.
