Deliberate mistake: When Basil is arguing with Polly and eventually decides to call O'Reilly, he trips over the gnome. However when we see Basil come out from behind the desk, he takes the gnome out of a side gap in the desk, perfectly out of reach of Basil tripping over it.
Continuity mistake: There appears to be a very obvious splice edit in this episode. When Basil manages to get Kurt off him after being pinned to the kitchen table, he pushes Kurt against the wall knocking him out. Before this Basil is lying flat on the table and we never see him get up to a standing position beforehand.
Revealing mistake: When Basil is out of the car and shouting at it after its final breakdown, you can see a crew member reflected in the right hand side of the windscreen giving John Cleese cues. It's not Cleese himself, as the reflection remains after he runs out of shot to get the tree branch, and the reflection doesn't mimic every action performed on screen.
Continuity mistake: When Basil is driving home the second time, he is turning into a street where a van is parked. When he turns the street is dry. In the next scene where he is backing away from the van, the street is all wet.

Continuity mistake: When Basil's car breaks down for the final time after reversing away from the van, watch closely on the garden path of the house right next to the car. The garden gate is open, and you can see it swing shut (look at the black shape just above the hedge) just as Basil says "One, two three." The gate was shut when he first reversed around the corner, but was open again after the shot cuts back to the car (after it's moved to the right along the pavement).
Deliberate mistake: When Basil asks Manuel to pull the hose on the fire extinguisher, the top of the hose falls off easily, resulting Basil to be squirted in the face. The bit where the hose is attached to squirts water out diagonally, but this would cause water not to go down the hose. This fire extinguisher was especially constructed to make sure the water was directed at Basil's face.
Visible crew/equipment: Just after Basil gets the duck from Andre, he tells Manuel to get the trolley. Basil then walks into the door, and the duck goes flying. You can briefly see the arm of the crewman holding the door closed. A few seconds later, Manuel comes through the door and stands on the duck. For about 5 seconds you can see the crewman's face.
Audio problem: Throughout the episode the picture Basil is distracted from putting up has no glass covering on it. However, when he smashes it at the end you can hear the distinct sound of glass breaking.
Continuity mistake: Towards the end of the episode, a couple of scenes before Mr Stubbs arrives, we see Basil start up the tape player prior to hiding in the kitchen. The garden gnome on the desk is right next to the tape player at this point. When Sybil turns the tape off the player has rotated 45 degrees or so (despite nobody else having come into reception in the intervening time) and the gnome is now further along the desk towards the camera as we look on the wide shot. The gnome in the next shot is seen beside the checking-in book when Basil wanders out of and back into the office a couple of scenes later, yet when Mr Stubbs is asking about the lintel for the new door shortly after that and we see Sybil writing in the book, the gnome has moved out of shot altogether.

Revealing mistake: In the scene where Polly brings Mr O'Reilly a cup of tea, it is obvious on several occasions that there is nothing at all in the cup. Not only does he hold it in such a way that you can see inside, but when Basil snatches it away nothing spills out.

Visible crew/equipment: Near the start of the episode, after the guest has told Basil that he will only be staying until Sunday, Basil walks from the dining room to the office, and the shadow of the camera following Basil can be seen in the reflection of the studio lights in the picture above the Drawing Room door.
Continuity mistake: After hitting O'Reilly, Sybil goes to the desk and grabs the phone. In the first shot, Sybil grabs the phone with her right hand, she puts it next to her ear and then put her left hand on the microphone. She turns her back to Basil and O'Reilly. In the next shot, the phone has not been put next to the ear yet, while Sybil's left hand is not on the microphone but on the cable.
Revealing mistake: In the part where John Cleese is smacking Manuel's head against the place where the dining room doors are supposed to be, you can see very that Manuel is kicking the wall right when his head is supposed to hit it, creating the sound of his head hitting the wall. Check it out because it's very obvious and hard to miss.
Visible crew/equipment: Just after Basil and an old woman leave the kitchen, the scene cuts to the interior of Mr. Lloyd's room. As soon as the first shot of the interior begins, a boom mic is visible for a split second at the bottom of shot.
Revealing mistake: When Basil smashes Manuel against the wall where the dining room is meant to be, we can see it is made out of cardboard. Notice how it begins to fall off, even though it is meant to be sealed and covered in wallpaper.
