Let Bartlet Be Bartlet - S1-E19
Factual error: In the Don't Ask Don't Tell meeting, the USAF Major is wearing a JCS service badge on his right. That is the position for females. It would actually be worn below his ribbons. He is also not wearing a name tag on his blue shirt after he takes his jacket off. That is the one mandatory item required on his shirt.
20 Hours in America: Part I - S4-E1
Factual error: The President is campaigning in Indiana and Josh, Toby, and Donna get stranded there around noon - but the shadows are quite long and it is obviously not noon in real time, but perhaps mid to late afternoon.
Factual error: In the show's final scene Ronna comes into the oval office to remind President Santos that it's nearly 6 PM and he needs to get ready for the various inaugural balls. The Oval Office is filled with sunshine, however in Washington D.C. in January the sun would have set nearly an hour before and it would be dark outside.
The Drop In - S2-E12
Factual error: Leo asks how long it will be before the missile system being tested will hit the target, and is told "two minutes, ten seconds". He decides the President should see it, and leaves to fetch him. But doing so results in them both arriving back In the Room exactly 3 minutes later. 7 seconds after that, they are told there are still 50 seconds to impact (but it should have occurred 57 seconds ago). After the 50 seconds pass, Leo states the impact will occur in 20 more seconds, and the moment of expected impact does pass at that time. In all, 4 minutes, 16 seconds pass from when "2 minutes, 10 seconds" to impact was announced. (00:01:30)
Factual error: When describing the location of the "oil refinery" / missile silo, it is said to be in the Oblast Region of Russia. Clearly, some intern was asked to Google Russian Regions and accidentally came back with the Russian word FOR region. It's like saying something was in State State or County County. Also, in the same episode, Bartlett berates the Russian ambassador about people being crazy in Minsk...which is in Belarus.
H. Con-172 - S3-E11
Factual error: When Leo is talking with Jordan about why he doesn't want the President to be censured, he states that this would be the first time a President was censured. This is untrue. Both Andrew Jackson and James Buchanan were censured by Congress (although Jackson's censure was later expunged). (00:11:25)
Factual error: Lord John Marbury says he is "the Earl of Croy, Marquess of Needham and Dolby and Baronet of Brycey." His title according to the British peerage rules would be "The Earl of Croy" and he would be called Lord Croy in conversation. Lord John Marbury would be what one of his younger sons also named John would be called.
Factual error: At the end of the episode, a chamber music ensemble plays at the White House. One of the close-up shots is of the oboist as well as the sheet of music on her stand. The music on the stand is not the same piece as that being played, and it's not even an oboe part, but rather a piano score of some solo instrument piece, as can be told by each system having three staves, two of which are bracketed together. (00:39:20)
Factual error: Whenever the king of Sweden is mentioned by name they always refer to him as "King Gustaf." The king of Sweden is actually named Carl XVI Gustaf. His given name is Carl Gustaf and he holds the throne as the sixteenth king Carl. Thus they should refer to him as "King Carl Gustaf" or, less common but technically correct, "King Carl." Since Bartlet has met the Swedish king in person and talked to him about Ellie's mathematical skills he ought to know the correct name.
7A WF 83429 - S5-E1
Factual error: In the television clip introducing the bombing in Turkey, the footage almost certainly comes from a Palestinian terror attack in the vicinity of Tel Aviv, Israel. Clearly visible in the frame is a Magen David Adom (Israeli Red Cross) ambulance marked with the Hebrew word "Dan" - a term for the area around Tel Aviv. The vast majority of raging fires that MDA ambulances responded to around Tel Aviv were the result of suicide bombings.
Factual error: When Will comes to Leo's office at the scheduled time of 6PM, the sun is shining brightly through Leo's window. Since this is the day after the State of The Union address which is mid-January, it would already be dark in DC.
Factual error: Near the end of episode 1 in series 6, General Alexander is briefing Leo, and the screen shows the Alpha strike headed east toward Syria from the USS Lincoln, which is depicted as being in the Mediterranean. In episode 2, he briefs the press, telling them that the strike was launched from the Lincoln in the Gulf.
Factual error: In the first shot after the recap, the overlay text reads "United States Capitol/Sunday/Inauguration Day". During this episode and the one that follows there is an inauguration day celebration and President Bartlet makes his inauguration speech. Historically, however, when inauguration day falls on a Sunday the celebrations and speeches are scheduled for the next day, a Monday. The president is still sworn in on inauguration day (March 4th until 1933, January 20th after that), but all other activities are moved back one day. The inauguration date has only fallen on a Sunday 6 times since 1798, and only twice since the current inauguration date was set, so it is understandable that this arcane but important bit of scheduling tradition was missed by the show's researchers. (00:00:45)
Chosen answer: A really annoying innate lack of sense. My friends and family say the same thing all the time, and I'm endlessly trying to correct them. I think people just don't know any better and (ironically) couldn't care less that they're speaking incorrectly.
