- Accidental Innuendo: The phrase 'glory hole', which carried an entirely different connotation in the UK at the time (it referred to a cupboard under the stairs. Make all the Harry Potter jokes you like), is repeated throughout. Please accept this fact and move on.
- Ensemble Darkhorse: Dr Emilio Sylvestri. In the commentary, the creators note that at film school screenings he always gets an immediate positive response.
- Gone Horribly Right: In some respects, as Kimmy illustrates, Pipes gave everyone watching exactly what they wanted.
- Harsher in Hindsight: Two interesting examples: In the fictional setting, the phone switchboard jams with calls from terrified viewers. This happened in real life as the programme was airing. Secondly, at one point Parkinson chides a distraught mother for allowing her children to watch a TV show after the nine o' clock watershed. The show creators would end up using that very point as part of their defense against subsequent criticism.
- Nightmare Fuel - Pretty much the whole thing, but particularly Pipes' few onscreen appearances either subliminally, or stalking the cast everywhere they go.
- Nightmare Retardant: Subverted. In the fictional setting, Craig Charles' role is to provide light relief to all the creepiness. It doesn't quite work out.
- Paranoia Fuel: An especially dark version of this, as viewers who thought it was real would have been led to think they might be letting a malevolent ghost into their home via their TV set.
