Good Night, Dear Heart - November 9, 1957 - S2-E17
Other mistake: Sam opens Hila's diary to a page. The translated voice-over mentions the 4th of July, America's independence and how she met someone with whom she could fall in love etc... The actual text on the pages mentions only the "Beginning of July" and how "3 bears and a zebra were born in the zoo. "Anton" was there and told her about it. His entire family was there and had a lot of fun." The right-hand page mentions how they had a wonderful day visiting the castle at Chiemsee where they had lunch. (00:21:02)
Other mistake: The closing credits on the DVD are for another episode, "The Kidnapped Prime Minister." (00:47:15)
