Riders of the Badlands (1941)
Charles Starrett: Steve Langdon, Mac Collins
Steve Langdon : Then you decided to take up denistry?
Bones : Oh, yeah, I was lookin' at a book he left back there and I figgered denistry wasn't nothin'. Pullin' teeth just took a little muscle.
Steve Langdon : And judgment.
Bones : Yeah, maybe I should have read the book instead of lookin' at the pictures.
