This is the second time Luke's had someone "visit" him from the Marines
Luke: You came to settle the score with me, Benson. Why don't you leave my family out of this?
Benson: Good morning, Luke. Or should I say Sergeant?
Luke: Lee Benson.
Benson: You haven't forgotten me. Well, I haven't forgotten you either. Those few years you got me thrown in the brig.
Luke: You got there all by yourself. You didn't need no help from me.
Benson: I'm finally gonna get even with you, Luke Duke. If it hadn't been for you I'd still be in the Marines. I'd have my stripes.
Luke: You got your stripes, Benson, only they run up and down.
Bo: Yeah, especially that big yellow one that runs up and down your back. That's what you get for shooting people who can't defend themselves.
Benson: You just keep running off at the mouth, boy!
Luke: Young man's got a right to speak his peace, ain't he, Benson? I mean you are gonna shoot him after you shoot me, ain't ya?
