Trivia / Look Around You

• Bonus Episode: A bonus, double-length episode about calcium (the unaired pilot) is included with the DVD of the first series.
• Knight Fever: Prince Charles is insistently referred to as "HRH Sir Prince Charles" throughout the second series, and thus appears to have been given an inexplicable knighthood in this universe — even though such an honour would be deeply illogical as it ranks far lower than his existing (and exceedingly high) royal status.
• Referenced by...: One xkcd comic features a graph plotting scary-sounding things as a function of how scary they actually are. To the right of the chart, so far off it's not even visible, scarier even than the nuclear football or flesh-eating bacteria, is the Helvetica scenario.
• You Look Familiar: Computer Jones previously appeared as the Ghost of Tchaikovsky's attendant.
