Visible crew/equipment: When Blackadder calls for Baldrick and asks for a raw turnip, as Baldrick enters, you can see some shadow moving on the left of the screen. It's not Baldrick's shadow and there's certainly no one else in the room that could make that shadow. (00:13:55)
Continuity mistake: When Blackadder, Queenie and Nursey are all comforting Melchett, there is a shot from the side view of Melchett, he is holding his head with his left hand. Then there is a shot from behind Melchett, he still has his hand on his head but when the shot returns to the side, Melchett no longer has his hand on his head.
Factual error: Dr. Johnson completed his dictionary in 1755, 7 years before the Prince Regent was born (1762). So it's unlikely for him to be asking the Prince for patronage.
Plan E: General Hospital - S4-E5
Continuity mistake: After his interrogation, Darling is able to run out of the doctor's office (albeit hobbled by the chair he is tied to) despite having been shot in the foot and having been seen visibly limping earlier.
Plan B: Corporal Punishment - S4-E2
Continuity mistake: Black Adder shoots the pigeon, and the feathers fly everywhere. One feather lands on Black Adder, just above his ear. In the next shot, the feather has moved up, on the other side of his side-part, towards the top of his head.
Factual error: During the theatre play you can see they are using electric stage lights. Nice move for a series plotted almost 300 years ago. (00:01:55)
Visible crew/equipment: In the shot after Blackadder has read up Baldrick's votes a microphone is visible in the upper right corner. (00:18:15)
Visible crew/equipment: During the conversation between Blackadder and Baldrick, as Baldrick explains what he spent the £400,000 on, we can see the shadow from the boom mike moving on Blackadder's fur coat. (00:28:00)
Visible crew/equipment: When Blackadder is at the doctor and the doctor says, "I think you are in luck though," while pointing at the board of "Principal Leech Points", you can see the boom mike pop in right above Blackadder. (00:12:45)
Continuity mistake: When Blackadder and the other soldiers are about to go "over the top", you can see two other soldiers standing behind Darling. They are presumably in the upper part of the trench. When Blackadder blows his whistle, you see all the soldiers climb onto their ladders and then start to rush over, side-by-side. In the next shot, when we see the soldiers emerging from the trench in slow motion, the other two soldiers are still back in the trench waiting for Darling to climb out before they move, as the two shots were filmed in two different studios.
Continuity mistake: When Blackadder, Baldrick and George are out in the no man's land, Blackadder screams and Baldrick asks why. Blackadder answers he put his elbow in a blob of ice cream while looking at Baldrick. When it cuts he is looking straight forward instead. (00:22:20)
Continuity mistake: When Blackadder calls for Baldrick to fetch his incredible strong ale you see Melchett holding his beer down. When it cuts the ale is up at his chest. (00:22:25)
Factual error: In Blackadder's Christmas Carol, during the Elizabethan part of the 1988 Christmas special, Queen Elizabeth asks Edmund if he has any last words before she chops off his head and sticks it on the Christmas tree. Christmas trees weren't introduced to England until Prince Albert (husband of Queen Victoria) brought it from his homeland in 1840.
Audio problem: "Blackadder Back and Fourth": Blackadder and his guests are going to the cellar where the time machine is kept. While they are going down the stairs, Blackadder says, "To his exact specifications." However, his mouth is shut and his lips don't move. (00:03:35)
Revealing mistake: When Baldrick is on the metal spit rotating by the fire, the fire is just a light up board.
Visible crew/equipment: When Blackadder is called to the Queen's first practical joke and he says he didn't laugh because his head would fall off, the Queen says, "If you don't start soon, your head will fall off", the boom mike is visible above her head. (00:09:55)
Continuity mistake: When George (dressed as Blackadder) is in the cellar and about to go upstairs, he has one cup on his tray, however when he arrives upstairs there are two cups on the tray.
Continuity mistake: When Blackadder throws the wine into the closet, some of the wine drops on the floor. When Queen Elizabeth arrives, there's no wine on the floor. (00:16:25)
Answer: According to the IMDB.com's quote page for Blackadder The Third, it's "Aahhhhh. Hot potato, orchestra stalls, Puck will make amends. Owwwwww."
