I haven’t seen “The Missouri Breaks” mentioned. It was a good one too.
I watched The Missouri Breaks in a theatre in small town Puente Alto, Chile in the mid 70s. The movie was in English with Spanish subtitles. There’s a scene where a rancher is helping a cow give birth (IIRC) and he exclaims “Slipperier than snot on a doorknob.” I burst out laipughing out loud at that line and everybody in the theatre turned to stare at me. The on screen subtitle only said “slippery” in Spanish, not exactly a humorous line.
