Dead weight
In “Second Thoughts,” a third-season “Dallas” episode, Pam (Victoria Principal) walks into Cliff’s bedroom and finds Digger (Keenan Wynn) packing.
PAM: Daddy, you’re really going?
DIGGER: Yeah.
PAM: Why?
DIGGER: I’m not needed here. Nothing to keep me.
PAM: Well, there’s me. And Cliff. We’re family. We need each other.
DIGGER: Oh, now come on, Pam. You’re a big girl now. You’ve got your own life to live. I’m just a dead weight. God knows, Cliff would be better off without me hanging around.
PAM: Please don’t go, Daddy. You’re not well.
DIGGER: I’m better off away from here, where I can work. Keep myself occupied.
PAM: If you want something to do, maybe I can help.
DIGGER: The subject is closed. Don’t you see, Pam? I’ve got to go. I can’t keep hanging around, and feeling used up and worn out. I mean, if I can’t work the field anymore, well, I’ve gotta find something else. Work in an office. Drive a truck, anything. But I’ve got to feel useful again.
PAM: Well, would you like a ride to the airport – or were you going to walk your way to Galveston?
DIGGER: Well, now, if you’re offering me a lift, I guess I could hardly refuse. You could give me a lift to the bus station. I don’t fly unless I really have to.
They exit.
