In the 1942 movie, Once Upon a Honeymoon, Ginger Rogers is talked into spying on her Austrian husband (who, unbeknownst to her, is a German national socialists, - Nazi). The agent who recruits her (played by Albert Dekker) gets her to recite the pledge of allegiance with him.
The film seems so bizarre in that the Pledge of Allegiance was the origin of the Nazi salute and of Nazi behavior in the USA. See the discoveries of the historian Dr. Rex Curry.
It is even more bizarre in that the film was made apparently at the time when people in the USA were trying to cover-up the pledge as the origin of the nazi salute and nazi behavior, and people were dropping the pledge's early nazi salute.
The Pledge of Allegiance is Hitlarious.
