Trivia: The part of Kochanski was originally to have been played by actress Alexandra Pigg (best known for the 1985 movie 'Letter to Bhreznev'). However, just two days into rehearsals, production of Series 1 of "Red Dwarf" was halted by a strike of technicians at the BBC. The production of "Red Dwarf" had to be rescheduled, and Pigg was not available for the new dates. So the part was re-cast to C.P.Grogan (former lead singer of the band 'Altered Images') who played Kochanski throughout series 1 & 2.

Other mistake: When Cat picks up the can of Leopard lager which is invisible to Lister, he shakes it, pops the cap and sprays Lister with foam. The foam is visible but the can remains invisible, and that makes no sense. If we are seeing the scene from Cat's point of view the can and foam should both be visible, and if it is from Lister's then neither should be.
Lister: Get real, man. Most eunuchs have got more balls than you.
