"Missing" Episodes
In the sleeve notes of the Series One audiobook, written in 2006, series writer Graham Duff asks for assistance in finding episodes "currently missing from the BBC archive". The article is a parody of when television and radio stations such as the BBC used to "wipe" episodes of TV and radio programmes, and record over them, especially the loss of many early Doctor Who and Dad's Army episodes. In the notes, Duff claims that as a result of wiping, "many classic Nebulous episodes were destroyed, along with editions of iconic Radio 4 shows such as Gardeners' Question Time and Money Box Live."

According to Duff, even after the discovery of two episodes from Season 6 – "The Man Who Kissed His Own Brain" and "Tomorrow is a Tunnel" –  which were apparently found in the basement of a LDS Church near Chorley in September 2005, there are still a further 23 episodes officially missing from the BBC archive, including the entirety of Season 10.

Duff describes the "Missing" Season 10 episodes as follows:

Duff also claims that in October 2005, a 49-second segment of the otherwise "missing" Season 8 episode "The Flesh Eating Cushions" was discovered in a locked BBC cupboard.
