Corrected entry: In this episode, Charlie says that he was hired by Debbie Fiderer, and that she was fired for it. However, in season one, we see that Josh is the one that hires Charlie.
The Indians in the Lobby - S3-E8
Corrected entry: When at Thanksgiving Josh is trying to get to his mother's house in South Florida, Donna tells him she got him on standby to a direct flight to Boca. The tiny Boca Raton airport is actually only for private planes; commercial flight go into West Palm Beach or Ft. Lauderdale airports. (00:32:20)
Correction: Commercial flights are often redirected to alternate, smaller airports during busy travel times like Thanksgiving. I live in a city with an international airport and a civil airport across town, and the civil airport is equipped to land a commercial flight if needed.
Corrected entry: President Bartlett prides himself on his elocution and knowledge of trivia. However, as he escorts Abbey toward the party, he goes on about a vintage from the Willa-mette Valley. One would think he would know that Willamette is pronounced "Will-a-mette", with the emphasis on the second vowel.
Correction: The President has been shown to make mistakes, even when 'showing off' intellectually. This isn't the first time, and a minor gaffe in a private conversation. If this type of thing happened in a diplomatic situation and went un-noticed, it would be a 'mistake', but as is, it's merely a human trait.
Correction: In the scene where Josh first interviews Charlie (who had applied for a messenger job), Josh says that "Mrs. DeLaGuardia in personnel" had sent Charlie to Josh because she thought Charlie would be a good candidate for the "body man" position. Mrs. DeLaGuardia was later fired for this, since the son of a supporter of President Bartlet's was supposed to get the job that ultimately went to Charlie. This is why Charlie fought so hard for Debbie Fiderer (who is actually Mrs. DeLaGuardia, now divorced and going by her maiden name) to get Mrs. Landingham's old job - he felt responsible for her being fired in the first place.
