The Spanish Inquisition - S2-E2
Revealing mistake: At the very end when The Spanish Inquisition bursts into the courtroom, you can see that Biggles is not played by Terry Jones (as he is playing the accused judge in the court sketch).
Continuity mistake: In the Marriage Counselor sketch, Deidre Pewty is wearing such a tiny miniskirt that when she sits we see she is wearing white knickers. When she undresses behind the screen she throws a pair of black knickers out.
Plot hole: In the Upper Class Twit of the Year Show, there are five contestants. However, after Oliver runs himself over, in the events that follow there are only four props for the remaining twits (four mannequins, rabbits, and guns); since Oliver's death was unforeseen, shouldn't there be five of each? (This mistake, by the way, is rectified in the film version of this sketch).
Blood, Devastation, Death, War and Horror - S3-E4
Visible crew/equipment: When the Merchant Banker sends Mr. Ford through the trap door, you can see a crew member waiting to catch him below the stage. (00:06:50)
Other mistake: In the Y valley travel agents sketch Smoke Too Much states that he can't say the letter C. But he uses several Cs before Bounder suggests he uses the letter K, even saying "I can't say the letter B." He says that he'd never thought of the letter K before.
Factual error: When the allies are testing their joke on the private in the field, just before he starts laughing at it, a bright red car drives past behind him. You can see it in a break in the trees. This sketch is set in WW2, and the car is obviously not from that era.
The War Against Pornography - S3-E6
Revealing mistake: When John Cleese (as Long John Silver) falls over after being shot with a tranquilizer dart, you can see his real leg, which was tucked behind him when using the peg leg. (00:20:10)
Other mistake: During the Toad Elevating Moment, John Cleese enters and says "Good evening," even though his character only says the beginnings of words (he should have said, "G- Ev-"). (00:06:05)
Visible crew/equipment: Just after Florence Nightingale gets knocked out, a crew member can be seen behind Michael Palin for a short time.
Suggested correction: The scene is set in an active television studio filming a sinister quiz show. The crew member visible is one of the crew of the fictional television show.
Oh, You're No Fun Anymore - S1-E7
Continuity mistake: During the science fiction sketch, when Eric Idle is reporting his blancmange sighting to John Cleese the clock in the background jumps backwards a few minutes.
Oh, You're No Fun Anymore - S1-E7
Visible crew/equipment: At the beginning of the 'Camel Spotting' sketch the shadow of the boom mike moves back and forth over Eric Idle.
Njorl's Saga - S3-E1
Audio problem: In the 'PC Pan-Am Gives Evidence' sequence (part of Series 3, Show 1), there is a loud, off-camera crash at 16'15", followed by hysterical audience laughter and a Palin visibly trying to stifle a laugh. This is because the heavily-bandaged 'Njorl', who had been replaced at that point by a dummy (enabling his head to be removed in the next scene), fell backwards off the podium, and had to be re-positioned by the crew. Filming presumably stopped, as a cutaway of Njorl appears in the middle of Pan-Am's address. The edit is also very audible, as Palin's speech suddenly plummets in volume.
Revealing mistake: The Italian evening class runs from 7 to 8 PM. The clock at the back of the classroom reads 10 to 2.
Man's Crisis of Identity in the Latter Half of the Twentieth Century - S1-E5
Continuity mistake: At the start of the interview sketch, and at several times throughout, Cleese says he's interviewing people for a management training course. At the end, however, he suddenly claims it was a job interview.
Continuity mistake: At the beginning of the 'Ministry of Silly Walks' sketch, John Cleese is holding his briefcase in his left hand. when the shot changes to outside, showing him leave the newsagents, it switches to his right.
The Royal Philharmonic Orchestra Goes to the Bathroom - S1-E11
Other mistake: William Knickers' letter, complaining about the sketches, starts "I strongly object ..." but the voiceover says "I object strongly ..."
Mr. & Mrs. Brian Norris' Ford Popular - S3-E2
Continuity mistake: When Mr. Norris sets out on his expedition, it is April 24. But when we see his diary, the day is the 24th, but the month (on the top of the page) says "October."
Continuity mistake: At the beginning of the vegetarian restaurant sketch, Eric Idle stands right behind the pointy sculpture. It is quite short and in some shots the points of it are visible right at the bottom of the screen, but in other shots people stand and walk through right where it is meant to be. And in the final shot, when Eric is complaining about the punchline, it is definitely gone.
Njorl's Saga - S3-E1
Deliberate mistake: Eric Idle's 'Stock Exchange Report' (in Series 3, Show 1) has a very obvious edit in the middle. This is a monologue delivered without cutaways, so the jump in the video tape is very easy to spot. Whether this edit indicates material removed or a simple joining together of two takes is unclear. However, since Idle gets drenched with water at the close of the routine (and given that, under BBC constraints, there was no time for drying out), we can assume that he must have made his fluff quite early on in the piece.
Revealing mistake: Near the end of the Bishop sketch, when they use the man as a battering ram, you can see the entire wall behind them tip as they smash through the door.
