Continuity mistake: During the Ministry of Silly Walks sketch, in the office, John Cleese pulls out a film-projector from his desk, and you can see the power cord plugged into the back of it. After the spoof black-and-white film footage showing the silly walks, John Cleese throws the projector away. The power cord, which was originally plugged in, has disappeared completely.
Scott of the Antarctic - S2-E10
Revealing mistake: In the last shot, the familiar 16 tons weight is broken at the top, showing that it is in fact not a solid weight, but a hollow box.
Continuity mistake: We are told that the Germans develop and broadcast the "V-Joke" in 1944, but when we cut to Terry Jones and Graham Chapman listening to their radio and hearing the joke, the caption reads "1942...Somewhere in England".
Character mistake: When Mrs. Bun asks the dining lady if she has anything without spam in it, she forgot about egg & bacon, and egg, sausage & bacon. Those had no spam in them.
Salad Days - S3-E7
Continuity mistake: In the 'Sam Peckinpah's Salad Days' sketch in Series 3, Show 7, the scene suddenly changes from a bright sunny day to a pitch black night - this was apparently due to technical delays, but the effect makes it look like an extension of the 'pretentious director' parody.
The Nude Man - S3-E9
Other mistake: During the "Olympic Hide and Seek Final," Terry Jones, as the Paraguayan, has a little difficulty with his Spanish numbers. Besides mispronouncing many of them, he says "quince," the Spanish number for fifteen, instead of "cinco," the Spanish number for five. He actually has to pause to remember the Spanish number for fourteen, "catorce".
Character mistake: When Mrs. Bun asks the dining lady if she has anything without spam in it, she recommends "spam, egg, sausage and spam". This was not in the menu that the dining lady read aloud at the start of the sketch.
How to Recognise Different Parts of the Body - S2-E9
Other mistake: The final 'How to Recognise' announcement is originally written as "Number thirty. The End." When the show was broadcast, it was "Number thirty one. The End", yet all the other numbering tallies with the script. So either Cleese miscounted on the night of recording or they inserted another one which was later cut.
Character mistake: During the "Communist Quiz", Eric Idle fails to mention that "the Hammers" is the nickname of West Ham United.
Chosen answer: That would be Terry Gilliam, who played a lot of non-speaking roles in the series, and some speaking ones like Cardinal Fang in 'The Spanish Inquisition.' He did all the animation as well, but I'm sure you knew that.
