We learn of the morning that Rimmer spent on the Samaritans switchboard - when he drove all five callers to suicide, despite one being a wrong number! The Brittas Empire (1991) features one Gordon Brittas (also played by Chris Barrie) who had a similar experience, right down to the wrong number.
This is the first episode where we see the human face of Robert Llewellyn. He played Kryten and also played Jim Reaper.
This is the first episode where one of the Skutter's names is known ("Bob").
In the opening credits of Season 3, there is a picture of Kryten in a suit, moving his body to his left, and turning his head to his right, with a smile on his face. This picture is also shown in the Red Dwarf pictures screensaver. It was supposed to be from this episode but was never shown. It was also the only scene from the episode to be shown in the opening credits.
Kryten has no trouble lying to Hudzen-10 about Silicon Heaven, but he has to be coaxed by Lister in the next episode to be able to lie to his fellow shipmates. Perhaps he had no problems lying to fellow mechanicals, but couldn't lie to humanoids or holograms.
