The Hitchhiker's Guide to the Galaxy (1981)

Episode 3 - S1-E3

Revealing mistake: At the point where someone gets a small bruise on the upper arm, the crew are all in a pile and thrashing about on the floor. There are 5 pairs of legs instead of 4. Arthur is in his pajamas, Zaphod is in orange trousers, Trillion is lying on top of Ford and Ford is too far away for them to be his legs. [The fifth pair of legs belong to the person playing zaphod's third arm - doesn't mean it's not a mistake, but that's where they come from.]

Arthur Dent: You know, I've always had this feeling there was some greater purpose.
Slartibartfast: No, that's just ordinary paranoia. Everybody in the Universe has that.
Arthur Dent: Well if everyone has it, then perhaps it means something.

Trivia: Douglas Adams makes several cameo appearences in the series. A drinker in the pub in part one, the man walking into the sea and a member of the Cirius Cybernetics marketing division in part two.
