Corrected entry: Contradicting what was said in the first ever episode of Red Dwarf ("The End") Lister says that he bought his pet cat, Frankenstein, on Titan, but in 'Ouroboros' he says he bought the cat while on Mimas.
Corrected entry: Frankenstein is too young to be pregnant. Therefore, she could not have been the ancestor of the cat race.
Correction: Female domestic cats reach sexual maturity at five or six months old, but don't stop growing until they are twelve to sixteen months old. Frankenstein isn't fully grown, but that is no indication of her sexual maturity - or pregnancy.
Corrected entry: Lister says that, as long as his "ouroboros" cycle continues, the human race can never become extinct. But this is not true: someday Lister will die. The baby he fathered will not replace him, because he sent it back in time, where it starts its lifespan at the same time as him (and thus dies at the same time as him). The cycle is self-reinforcing, but not self-perpetuating. Thus, when Lister dies, the human race will indeed be extinct. (00:28:15)
Corrected entry: At The End of the episode, Ouroboros, when the adult Lister places the infant Lister in a cardboard box (under the Grav-Pool table at the Aigburth Arms) the caption states "EIGHTEEN MONTHS LATER". At The Beginning of the episode, a definite date is stated - 26th November 2155. Presuming a normal full-term pregnancy, this indicates that (a) Lister was conceived in late April 2154, (b) born nine months later in the last week of May 2155, and (c) nine months old when he is found in the cardboard box.
Correction: Parts a and b are unfounded since Lister was conceived, born, and raised for 9 months in what is 'the present' for the show (3 million years in the future). He is then transported back through time and left as a 9 month old baby in a box under a pool table.
Corrected entry: If the people in the pub thought that Lister's parents wanted him to be named Rob or Ross (which is later confirmed when Lister works of what the words on his box meant) and presumably they told the orphanage this, how did he end up with the first name David?
Correction: His foster parents gave him the name they wanted out of contempt for whomever would be so callous as to leave their baby under a snooker table.
Corrected entry: In the episode 'Ouroboros', we see a Lister from an alternate dimension as a hologram - because he didn't go into stasis, he was killed in the radiation leak. However, in the first ever episode of Red Dwarf ('The End') it was established the radiation leak happened because of the fact Lister was in stasis and therefore Rimmer didn't have help in fixing the drive plate. There is an implication that, if Lister hadn't been put in stasis, the radiation leak would either never have happened, or been brought under control with few (if any casualties).
Corrected entry: In the flashbacks in the episode 'Ouroboros' Lister says the penalty for keeping his cat would be six months in stasis (which is what Kochanski gets in her reality), however in the very first episode of Red Dwarf ('The End') Lister gets 18 months in stasis as punishment for the crime.
Correction: Lister got a stiffer sentence for refusing to surrender Frankenstein. Captain Hollister might have gone easier on a woman for not being willing to give up the cat for dissection.
Corrected entry: In the first series, Lister smuggles a fully grown, pregnant cat on board. In series 7, the cat is just a kitten and not pregnant.
Correction: This takes place in a Parallel Universe where Kochanski was the one who was saved from the disaster which wiped out the crew. Therefore, it could be that in this dimension it was a kitten and got pregnant at a later stage.
Correction: Yes, that's right, but the flashback in which he states this fact takes place in Kochanski's universe, in which he may have got the cat on Mimas instead of Titan.
