One of my favorite Gilligans Island episodes

[Aristus]

2. That reminds me of an episode of "The Black Sheep Squadron" that I saw as a kid.

The Black Sheep captured a downed Japanese fighter pilot (played by Clyde Kusatsu, IIRC), and are trying to interrogate him. They are goggling at him, mugging, and trying to ask his name in broken Japanese.

After a few minutes of this, the Japanese pilot replies, in fluent English: "My name is..." (and I forget what it was, but you get the idea.)

A number of Japanese officers who fought in the war had attended university in the US, and spoke fluent English, and often treated American POW's compassionately.
