A Red Dwarf episode in which the crew is attacked by a shapeshifter that feeds on human emotions. Kryten loses his sense of guilt, Lister his fear, Rimmer his anger and Cat his vanity. Quite possibly the best Red Dwarf ever.

Memorable quote:

Rimmer: Erm, I think we're all beginning to lose sight of the real issue here, which is "What are we going to call ourselves?" erm, and I think it comes down to a choice between The League Against Salivating Monsters' or my own personal preference, which is The Committee for the Liberation and Integration of Terrifying Organisms and their Rehabilitation Into Society'. Erm, one drawback with that -- the abbreviation is CLITORIS'.
