Continuity mistake: Just after Kryten says 'you bet your ass' he is holding onto his groinal attachment over his shoulder. In the next shot, his arm is lowered. (00:12:00)
Continuity mistake: When the Cat picks up the golf clubs, his hair is sitting on his left shoulder. In the next shot it is behind his back. (00:10:40)
Suggested correction: His hair moved to his left shoulder when he turned his head and picked up the clubs, but you can see his hair go back behind him when he straightens his head.
Continuity mistake: After the Cat incapacitates Lister, the Cat complains about his collar being untidy, then steps aside. The next shot shows Lister stood on his own and the Cat is not visible at all. There was no time for the Cat to walk that fast between shots. (00:23:20)
Timeslides - S3-E5
Continuity mistake: Kryten needs to ask what a pub is, yet in the episode "Backwards" he and Rimmer worked in one for three weeks as the comedy act "The Sensational Reverse Brothers", and, later, were involved in a brawl in the same pub. Originally, the episodes were to be shown in a different order, which explains why the mistake occurs, but doesn't excuse it. (00:12:55)
Continuity mistake: When Lister rides his bike in the first scene, there is a Union Jack just behind his seat. When he stops, a US flag has appeared below it. (00:01:45)
Continuity mistake: When Lister cuts himself shaving he moves his locks behind his back, then in the next shot, they are over his shoulder again. (00:12:55)
Continuity mistake: When Starbug crashes through a vent, Lister leans to his far right. In the next shot, he is leaning to his left. (00:09:20)
Continuity mistake: The cuts on Lister's robot goldfish disappear when he throws it back into the tank after fixing it. (00:06:00)

Continuity mistake: When Rimmer asks Kryten if it is the time of year his head goes for retuning, the shadow on his face changes between shots. (00:09:15)
Terrorform - S5-E3
Continuity mistake: After the crew fire at the Self-loathing Beast and the room fills with dust, the Cat's left hand is up in the air. In the next shot he is holding the bazooka with both hands. (00:17:00)
Continuity mistake: When Bird-man's boots drop to the floor, the crew are looking straight forwards. In the next shot they are all looking up. (00:26:45)
