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.
Other mistake: In a number of episodes Mickey Bricks takes great pains to explain (usually to bent coppers) that he and his team are not thieves, making it plain that as a talented grifter he takes the high moral high ground over common criminals. The trouble is, he and every member of his team ARE thieves. In the very first episode "The Con Is On" Three Socks Morgan cleans out the bank accounts of a number of innocent people by rigging an automatic teller machine. He is stealing money, either from them or the bank. Stacie Monroe is shown picking pockets in a number of episodes and in "The Henderson Challenge" both Mickey and Danny Blue steal wallets from bystanders, a trick Mickey repeats in "The Return of the Prodigal." He also steals the victim's car. There are too many other examples to list here, but Mickey's pride in his exalted position as a master conman is definitely misplaced.
Other mistake: At the start, it's nighttime when the unsub hides in the house of the soon-to-be victim who goes to sleep when her alarm clock reads 'Tue 11:06', and then we see the time morph to 'Tue 1:13' when the victim is sound asleep, before the unsub comes out of the closet to kill her. However, the time on the clock should actually read 'Wed 1:13'.
Other mistake: In the first episode it shows the house a mess and Danny and Joey and Jesse not wanting to clean. Then in the future the show portrays Danny as always being a neat freak, even as a child.
Other mistake: Right at the start, as they're crashing, the computer narrates their rapidly-dropping altitude in feet. But the "altitude" dial we're shown is in metres. Most noticeable as they cross the 3,000 mark, when the computer voice and the height say/show the same number at the same time, despite the different units. 3,000m would be more like 9,000 feet, or 3,000 feet would be more like 1,000m.

Other mistake: When Michael climbs up the rope to get to the room below the infirmary, the rope is hanging from the manhole cover, but he still manages to lift the cover whilst hanging from it. In the next shot where he looks down the manhole, its clear that there is nothing other than the rope he could have held on to while lifting the cover. An impressive accomplishment, defying the laws of gravity. (00:38:00)
Other mistake: While in the past on the Jocacean Memorial Planet, after Dacon is sent up on the wall by his commander, when the Venek Horde are coming over the wall Aeryn pulls one down and throws him to the ground, and we can see one of the armor pieces lying on the ground with the actor name "Dacon" written on the inside in English.
Other mistake: On scene at the traffic accident, when the woman and the boy with non-serious injuries are seated at the back of the ambulance, neither Roy or Johnny are going along with them to Rampart, yet Johnny puts the drug box inside the back of the ambulance with them, and the ambulance drives off. With their drug box! Captain Stanley even says that he'll advise dispatch that they're available for a run at the scene, while the guys will be looking for the dog.
Other mistake: In an earlier episode where Edie and Susan are driving Martha Huber's ashes to the lake to be spread, Edie gets a flat tire and Susan changes it. In this episode, all the girls are driving with Edie's ashes and they get a flat tire. Susan asks "Does anyone know how to change a flat tire?" Did she forget how?
Other mistake: When Rachel arrives at Central Perk, Monica introduces her to everybody, including to Chandler, as if they don't know each other. In later episodes, we learn that Chandler met Monica and Rachel a couple of times when they were in high school (including when Monica cut his toe off). Chandler even kissed Rachel once, and since Chandler always says that he hasn't kissed many women, he should have perfectly remembered Rachel, and Monica should have remembered that the two of them knew each other.
