You wouldn’t like him when he’s angry
In “Whatever Happened to Baby John, Part 2,” a third-season “Dallas” episode, Cliff and Pam (Ken Kercheval, Victoria Principal) are talking in his apartment when there is a knock at the door. Cliff opens it, revealing an angry Bobby (Patrick Duffy).
CLIFF: Wait a minute, before you start swinging, let’s talk.
BOBBY: Not this time, Barnes. This time, you’ve gone too far. [Enters and slams the door behind him]
PAM: Bobby –
BOBBY: And you knew he was here all along, didn’t you?
CLIFF: Wait a minute, I just got here. Can’t we talk?
PAM: He didn’t know anything about it.
BOBBY: You’d swear he could walk on water if he told you!
PAM: That’s not fair! Would you wait a minute?
CLIFF: I want my son, I’m gonna have him. I did not – I repeat – I did not kidnap him. [Bobby moves toward him, Cliff steps back] Now wait a minute, you can push me around the room all you want but that’s not going to solve anything. I think we should try to figure out who indeed took him. [Bobby growls and moves closer still.]
PAM: For God’s sake, listen to him!
CLIFF: I swear I did not kidnap him. I wasn’t even in Dallas.
PAM: He’s telling the truth.
CLIFF: Let’s stop wasting time. We can be at each other’s throats tomorrow but today – for today – let’s try to find my boy.
BOBBY: Okay.
CLIFF: Okay.
