The Moonbase:

10ep 2 – Polly serves the moonbase staff coffee in a corridor outside the medical bay. Shortly afterwards, one of the crew becomes infected with the Cyber-illness, the captain goes to take a sip of his coffee and the Doctor swats it out of his hand. As it flies through the air, you can see that only sugar spills out of the cup.

20ep 2 – When a Cyberman shoots at Polly (she is tending Jamie at the time), he misses, but Polly falls over anyway.

30ep 2 – The Doctor says he gained a doctorate under Joseph Lister in Glasgow in 1888. However, in reality Lister left Glasgow for Edinburgh eleven years before that date.

40ep 2 – When Polly expresses her doubts about his doctorate, the Doctor says says, "Polly, are you suggesting I'm not confident to carry out these tests?"
[I'm confident he should have said "competent"]

50ep 2 – The Cyberman that gets off the bed in the sick-bay nearly sends the whole thing flying.

60ep 4 – After Dr. Evans knocks out the Gravitron operator, he takes his hat and puts it on backwards. Next time we see him, it's on the right way around.
[Demonstrating an admirable amount of fashion sense, despite being infected by a deadly virus]

70ep 4 – When the Cybermen blast a hole in the dome, they also blow a few holes in the story's credibility — like why does the air get sucked out of the dome so slowly? Why did the Cyberman only blast one hole? And how long would that flimsy tray really hold out against a total vacuum?

80ep 4 – The doors and walls wobble badly as Jamie and Ben barricade the entrance to the medical unit.

90ep 4 – After the travellers make their exit at the end of the story, the doors of the control room fail to close properly behind them.

100ep 1-4 – Cockney sailor Ben inexplicably becomes a scientist for the duration of the story — so a bloke who normally thinks that a particle accelerator is a type of hoover suddenly knows that interferon is a viral antibody and that nail polish remover contains acetone.
[For this one, you can blame Jamie's last-minute addition to the cast, which meant that lines had to be moved around between characters.]
