Character mistake: When Josh is giving his WWII example to Donna, he talks about "France, Austria and England being pounded by the Germans." Except Austria was incorporated into the Third Reich after the Anschluss of 1938; it was essentially part of Germany for all intents and purposes. It therefore was not being attacked by the Germans at all. One would have thought Josh, who shows a firm grasp of WWII information in other episodes, would have known this. (00:31:20)
Character mistake: Someone set up the chess board incorrectly. White should be on the right. (00:09:20)
Somebody's Going to Emergency, Somebody's Going to Jail - S2-E16
Character mistake: In this episode the Organisation of Cartographers for Social Equality claims the cartographer Mercator is German. He is in fact Belgian. He was born Rupelmonde Belgium, March 5, 1512 and died at Duisburg Germany, December 2nd, 1594. (00:24:00)
Suggested correction: Although Mercator was born in Rupelmonde, it was during a visit his parents were making to the town. His family was ethnically German, as they came from Gangelt in the Holy Roman Empire. This is also where Mercator spent much of his adult life (specifically in the German city of Duisburg). Calling him German is technically correct.
Character mistake: While in the Situation Room Leo says twice "we need the calvary." According to Webster, calvary is a proper noun that refers to the hillside on which Jesus was crucified. Cavalry is a group of highly mobile army troops. Leo meant to say "cavalry" but mispronounced it. The subtitle is correct with the spelling "cavalry." Leo would definitely know better. (00:19:00)
