Character mistake: The party is supposed to be "One of the premiere social events of the season", but the only people invited (Higgins knows for sure who is gonna come, so it's not like there's low attendance because of the weather) are a Prince from a fictional European state nobody knows about with his commoner wife, the editor of a poetry magazine that needs Robin's funds to survive, a sports star and Robin's accountant. 5 people in total, already all in Robin's pocket, and nobody else in attendance. While you could say that having royalty and a golden glove winner is certainly noteworthy, those people don't meet anyone else. Hardly a 'social event'. (00:04:00)
Character mistake: Higgins addresses constantly the Prince and Princess of Turbia as "Your Majesty." For an expert of protocol as Higgins, it's quite odd to make such a mistake; "Your Majesty" is used for royalty with a rank higher than Prince (kings, emperors). Paradoxically, Magnum gets it right, calling both "Your Highness." (00:06:30)
Character mistake: Higgins is narrating one of his stories, this time implying that he helped Hemingway write "The Old Man and The Sea." Normally Higgins' stories are somewhat plausible because of factual accuracy that leaves room to be taken at face value, but here he says that it happened in "The Florida Keys, '53 or '54, it was." while "the manuscript was only in the outline stage." The novel was published in 1952. (00:10:30)
