Corrected entry: Lister does not seem to know much about his childhood, as he tells several contradicting stories about it. In series 2 Lister talks about how upset he was when his father died in the episode "Better Than Life". It is possible that he was talking about a foster father when he said this, but we learn in the episode "Ouroboros" in series 7 that he was abandoned, and never knew his parents at all. He also said in series 7 that he lived with his granny too, which leaves the question that if he knew his own granny, then why didn't he know who his parents were? Three different stories of his childhood.
Corrected entry: During the episode "Thanks For The Memory" in series two after Rimmer realizes that some of his memories where actually Lister's he says "no wonder I remember having my appendix out twice" (or something like that) meaning that Lister has had his appendix out. But during the episode "Legion" in series 6 Legion takes out Lister's appendix.
Corrected entry: Unfortunately the whole basis of the show is one big factual error. Throughout the series we see that Red Dwarf sustains damage from collisions, explosions, and so on. Most important of all, the rocket engine nozzle - surely made from the strongest materials available - has been punctured by some kind of impact. The systems require constant maintenance by humans (painting, repairs, etc), so skutters are not enough by themselves. So, we know that Red Dwarf is not made of some sort of fictional, indestructible materials, it is made of the kind of metals, plastics and other construction materials we build space shuttles and the like out of nowadays. So, after three thousand - never mind three million! - years the whole ship would be a clump of useless, corroded junk. The rubber and plastics in seals, electronic components and furniture would have crumbled to powder. The electronics themselves would have failed after a few hundred years at most. Metals in contact with liquids in pipes or reservoirs would have oxidized, and even the oxygen in the air would have been corrosive after that amount of time. Red Dwarf is not immune from the effects of long term decay and deterioration - if it were when Lister was released from stasis he would have found rooms full of relatively intact dead bodies instead of piles of crumbled dust. After three million years in space Red Dwarf would have been a pile of scrap, fatal to anyone going near it; subject to slow, subtle but constant radioactivity in space, after three million years it would be hotter than the inside of a working reactor.
