Very Manly(1962)

Train conductor Manolin warns passengers Don Fiero and his daughter Ava about local bandits and asks them to bear arms in defense of the train. Don Fiero declares that defending the train is not their responsibility, and the two literally hide their heads in buckets of sand and post signs reading “Neutral, Do Not Disturb.” The neutral passengers are the first to be robbed by the bandits, Lios and Chente.
