Corrected entry: A well-documented bit of censorship involves Series 2, Show 6 (first broadcast 20/10/70). This show featured an animated fairy story where a prince finds a spot on his face. "Foolishly, he ignored it," informed Carol Cleveland as the narrator. "And six months later he died of cancer." Although this was originally transmitted intact, the BBC were worried, and insisted that the word "cancer" be replaced for a repeat showing in August 1971. The word "cancer" was thus replaced by the word "gangrene". Unusually for the series, the word 'gangrene' does not appear to be voiced by any of the Python team themselves. To underline the fact that the word "cancer" had been replaced (and as a protest against the censorship?), a male voice replaces Carol Cleveland's narration for this one word only.
Corrected entry: Before the "There's been a murder" sketch, the narrator (who names different parts of the body throughout the episode) says "Number 29: the interior of a country house." At the end of the episode, he says "Number 31: the end." He never said number 30.username
