Green Berets. Col Kirby (John Wayne) talking to Beckworth (reporter played by David Jansen).
M/Sgt Muldoon had just finished showing a group of civilians communist weapons seized in Vietnam. Beckworth ambles over to Kirby and says your brainwashed sergeant didn't sell me. Sell you on what asked, asked Kirby. That we should be in SE Asia. Kibry asked, You ever been to SE Asia? Beckworth looks at the ground and says no. Kirby replied, "Uh, huh," and walked away.
The Duke could convey a lot of contempt with just two words.
John Wayne used the character name Kirby in several movies. I know one was Fort Apache; don't recall the others.
