In “If at First You Don’t Succeed,” an eighth-season “Dallas” episode, J.R. (Larry Hagman) arrives at the Ewing Oil building, where Pam (Victoria Principal) is waiting for him.
J.R.: Well, you got a lot of nerve coming around here after what your brother did to mine.
PAM: What were you doing there yesterday when my brother was arrested?
J.R.: You consider that your business, do you?
PAM: Yes, I do, because I think you had something to do with it.
J.R.: Well, what on earth could I have to do with it?
PAM: How did you know he’d be arrested at that precise moment?
J.R.: Well, I have friends at the department. I went down there to see the expression on that worm’s face when the police arrested him for shooting my brother.
PAM: Let me tell you something, J.R. If he did shoot Bobby, it was because he thought it was you — and he had every reason to shoot you.
J.R.: You know, I’m getting kind of tired of that old song. Mean, nasty J.R. beating up on poor, innocent Cliff Barnes. You’re sounding more and more like him, you know that?
PAM: Well, that’s fine with me because I’m beginning to sound more and more like a Barnes, thanks to you. I’ve never believed in the Barnes-Ewing feud, J.R., but now I’m going to join it. I’m going to do everything I can to help Cliff. And I’m not going to rest until all our family scores are settled!
