This reminds me that Monty Python and the Holy Grail contributed actual historical knowledge about Arthurian legends to my knowledge base while growing up. Other examples of Python unintentional education include knowing the names of a myriad of obscure cheeses (the cheese shop skit), a shocking number of anachronistic synonyms for death (the parrot skit) and notable contributions of the Roman Empire (Life of Brian 'What have the Romans ever done for us?' skit).
While it didn't contribute to my GPA at the time, I'm sure I could name more notable philosophers than any other 8th grader in my school (philosopher's song skit). However, in high school it did spark the interest to look up and read about each of the philosophers in the song.
You forgot Latin. Romanes eunt domus
See also: witches, and how to detect them. Bonus points for recognizing Australians.
The problem is that comedy is frequently not factually accurate.
Roman Imperial contributions? Was Roman wine better than pre-Roman wine in that region? Did they improve sanitation, irrigation, medicine etc.? Rome was an oppressive slavery based society.
Then what about the Spanish Inquisition sketch? It keeps repeating "fanatically devoted to the Pope"" The Spanish inquisition was an arm of the Spanish monarchy, at least two Popes tried to shut it down, and some historians have suggested one of its aims was to reduce the power of the Papacy.
I do like the Philosopher's Song, the Dead Parrot and Cheese Shop.
Other comedies are no better. Black Adder has a witchfinder (an early modorn innovation) in a Medieval setting.
Pop culture is not historically accurate!
