- Acceptable Targets: The Spanish Inquisition are on the mission to convert the Jews, who are constantly abused and tortured for laughs. (Bonus points for Torquemada who is played by a Jew.)
- Author Appeal: The Roman segment ends with the main characters emigrating to Judea, plus, the final segment is called "Jews in Space" with the Jews defending themselves successfully against attack.
- Crosses the Line Twice: The Spanish Inquisition torturing and forcibly converting countless Jews, Muslims, and other "heretics"? Horrific. The Spanish Inquisition doing so in song? Hilarious.
- Arguably, the inclusion of this scene implies that the line was never there to begin with.
- "Funny Aneurysm" Moment: There are several scenes where King Louis XVI takes sexual liberties with his female servants and proclaims "It's good to be the King." Fast forward to 2016 and 2017. What Do You Mean, It's Not Political?
- Genius Bonus: Torquemada is played by Mel Brooks. At first, it might just seem like comedic irony to have a man who led a major persecution of the Jews to be played by a Jewish actor...unless you know that Torquemada was himself ethnically Jewish.
- Hilarious in Hindsight: Inverted. The narrator contrasts 'the first homo sapien marriage' with 'the first homosexual marriage' back when the idea of same-sex marriage had barely occurred to most people.
- Ho Yay: DeMonet and Bearnaise.
- Memetic Mutation: It's good to be the king!
- One-Scene Wonder: Bea Arthur as the snarky unemployment clerk in the Roman Empire sequence. "Did you bullshit last week?"
- Special Effect Failure
- The synchronized swimmers emerging from the water with lit sparklers on their heads was achieved by filming them going down into the water and playing it backwards. It works... until you see the smoke from the sparklers go back into them.
- When the Roman soldiers lying on the ground, stone from the giant blunt that Josephus lit to slow them down, the cloud of marijuana smoke is rather obviously sped-up stock footage of clouds superimposed over them.
- Invoked in the King Louis segment. The king's impersonator tries to escape down a hallway from the French commoners' revolt, only to get stuck in the narrow end of the set's forced perspective.
- Watch It for the Meme: Some people watched the movie just to see the Spanish Inquisition. We guess people really can expect the Spanish Inquisition.
