Continuity mistake: As the crew enter the game, Lister pushes the door to the beach open. However in the next shot, the door is opening from the other side, i.e. Lister is pulling the door. (00:16:10)
Continuity mistake: When Marilyn Monroe waves to the Cat on the beach, in the next shot her arms are by her side. (00:16:50)
Continuity mistake: When the bike appears on the beach, the front tyre is above the level of sand. In the next shot it has sunk by about an inch. (00:17:50)
Continuity mistake: When Lister and the Cat put their sunglasses on, Rimmer's tie changes between camera cuts from over his shoulder to neat and straight. (00:18:00)
Continuity mistake: The sand that lands on Rimmer's shoulder when Lister and the Cat drive away on the bike disappears in the next shot. (00:18:10)
Continuity mistake: When Rimmer is standing on the beach and conjures up the green car you can see the wheels are partly in the sand. When he then gets into the car, tyre tracks are visible behind it. When he starts driving off, the tyre marks are now gone. (00:18:25)
Continuity mistake: When the Cat and Lister are playing golf, they stop next to a bed with Marilyn Monroe sitting on it. When the camera angle changes, they begin walking from the other side of the bed. Also Marilyn Monroe is now kneeling. (00:24:20)
Continuity mistake: When the Cat is kissing the photo of the mermaid, in the next shot the photo has disappeared. (00:24:50)
Continuity mistake: When Rimmer is talking about Yvonne McGruder, Lister is not wearing a hat. When we see the black box recording of the conversation, Lister is now wearing one. (00:08:25 - 00:16:45)
Continuity mistake: When Rimmer falls asleep whilst Lister is doing the jigsaw, there is a whisky bottle on the table. Later in the episode, when being viewed on the black box, the whiskey bottle is no longer on the table. Lister could not have thrown it away since he left the table to the Hologram Simulation Suite at The End of the scene. (00:10:20 - 00:19:35)
Continuity mistake: When Lister is doing the jigsaw and Rimmer starts singing in bed, the pint mug on the table has nothing in it. Later on, when Lister returns after giving Rimmer his memory, an inch of whisky has suddenly appeared in the bottom of the mug. (00:10:20 - 00:19:35)
Continuity mistake: In 'Thanks For The Memory', both Lister and The Cat injure their left feet when they drop the gravestone; but The Cat is seen to be wearing a plaster cast on his RIGHT foot. (00:12:10 - 00:27:00)
Continuity mistake: When Lister and the Cat are on the moon, their casts keep appearing then disappearing. (00:15:15)
Continuity mistake: Just before Lister says 'I'm going to give him Lisa Yates' he is looking forwards. When the camera angle changes he is looking at the Cat. (00:18:15)
Continuity mistake: When Lister and the Cat first see Lisa Yates on the screen, their shoulders are together. In the next shot there is a wide gap between them. (00:18:30)
Continuity mistake: When Rimmer is talking about Lisa Yates to Lister, his tie is undone. When it cuts to the black box camera, his tie is correctly tied. (00:22:10)
Continuity mistake: When Rimmer is about to tell Lister how many times he made love, Lister tells him that he'll "wake up in the morning with a hangover." But Rimmer and Lister already have fallen asleep and woken up, and they have the hangovers right now.
Stasis Leak - S2-E4
Continuity mistake: The second time we see the hologramatic Rimmer pass Rimmer and Lister in the corridor, two other people have appeared walking past. (00:04:00 - 00:18:25)
Stasis Leak - S2-E4
Continuity mistake: The second time we see the scene with Rimmer's head popping through the table, the line 'There, that wasn't too bad, was it?' is missed out. (00:04:40 - 00:19:20)
Stasis Leak - S2-E4
Continuity mistake: In the lift, when the woman in the video is explaining how the lift works, she mentions "a bag will drop containing sedatives and cyanide capsules", pointing upwards. The shot cuts to Lister, and the woman in the video can be seen to the left of shot, with her arms at her side. (00:08:35)
Answer: The cello is a large four-stringed instrument, which, when it is played, stands vertically on the floor between the player's legs (assuming they are seated). If it is to grow as large as the other instuments mentioned will, it would require a rather unseemly lack of femininity to be able to encompass it with the legs.
