Plan E: General Hospital - S4-E5
Corrected entry: During George's first day in the hospital, he mentions in his letter that Blackadder 'lay down and stuck his foot over the side of the trench'. The trench walls are at least 8 feet tall, so there's no way Blackadder could have done this.

Corrected entry: Blackadder makes the joke, "I imagine he went to one of the great Universities, Oxford, Cambridge, Hull." This is probably around 1916, but Hull University didn't exist until 1927. We cannot put it down to the joke either, as he explains later the nurse failed to point out its quality, not its existence.
Correction: The original question by Blackadder was not a joke, it was a deliberate mistake to trick Nurse Mary. As for the explanation later when he reveals her to be the spy, his exact words are that only two of them are great universities. The mistake is only valid if he had emphasised the word universities which he does not. His words can easily be interpreted as saying that only two of them are universities which was, at the time, true.

Corrected entry: In the beginning of the scene, Nurse Mary is reading a newspaper. She puts it on the sofa, but few shots later, the newspaper is gone. (00:21:50)
Correction: The end and back of the sofa are open and if you watch carefully when she puts it down, the newspaper slides off the sofa and falls on the floor. We don't see the area where it must have fallen so there's no mistake.

Corrected entry: Black Adder says that there are four verses to "God Save the King." There are actually five, and technically there are six. However, the final verse is very anti-Scottish (added after the Jacobite rebellion of 1745-46), and is very rarely seen and even more rarely performed.
Correction: While this may be true, Blackadder is merely trying to confuse Darling into confessing he's a German spy.
Correction: The exact wording is that he lay on his back and stuck his foot over the edge. That doesn't exclude the possibility that he was lying on top of something.
