Deliberate mistake: When the unconscious, naked Asian doctor is removed from the warming tub, his hands are clasped over his crotch to protect his modesty, despite the fact that he shouldn't be able to do that, since he isn't conscious and his previously frozen limbs are now pliable and relaxed due to the heat.
Factual error: When Scully is performing the autopsy on Leonard Betts' severed head, she states "As remains are incomplete, all observations refer to a decapitated head." This phrasing is redundant. The proper terminology would be "disembodied head." As a medical doctor, Scully should know this.
Visible crew/equipment: During the scene when Mulder, Scully and the deputy approach the farmhouse there is a moment when Scully walks up to a chicken coop and a boom microphone with a fluffy wind cover on can be seen coming up from the bottom of the screen (Underneath Scully). (00:30:35)
Unrequited - S4-E16
Factual error: By its uniforms, rank insignia (i.e. point-down chevrons), drill and instrumentation (e.g. tubas instead of sousaphones), the military band performing at the re-dedication ceremony at the Vietnam War memorial in Washington is a Commonwealth (probably Canadian) band and not an American band. Unlikely at a formal military ceremony in the United States.
Continuity mistake: While Mulder is picking himself up in the synagogue's attic after being pushed/tripped, you can see that his gun is unloaded, with no magazine. (00:25:07)
Audio problem: Scully asks the deputy if the vests are necessary and he replies in the same scene. His mouth is way off from his reply. It's likely this is because the show was shown on 4:3 aspect ratio televisions at the time, and he would simply not be visible. Because the show was shot in 16:9, he is very much visible on modern televisions and the mistake is incredibly obvious.
Continuity mistake: The truck stolen by Mulder from the Russian labor camp is Unimog 406. However, during the accident scene, when it comes out of the woods and falls from the hill, it miraculously turns into Unimog 404 model. (00:13:30)
Unrequited - S4-E16
Continuity mistake: When Scully and Mulder run away from the dogs, the gate is fully open, while in the previous and next shot only the door is open. Plus their car standing in front of the gate is missing. (00:09:30)
Continuity mistake: The wedding ring Ariel is holding in her outstretched hand is either vertically protruding from the palm of her hand or is hidden inside of it, depending on the shot. (00:40:25)
Continuity mistake: While Mulder's waiting for Langly and Frohike to unlock the exit door, Gray-Haired Man keeps shooting at the glass door, and the increasing bullet damage on the glass doesn't stay consistent as more damage occurs, and changes between the closeups and wideshots.
Continuity mistake: When Mulder and Byers find Scully in Penny's room, there is a black stripe on the ceiling of the corridor, while in the scene when Scully is leaving the room there is no stripe there. (00:36:50)
Never Again - S4-E13
Continuity mistake: In the front shot Scully holds the photo with 2 fingers (thumb and index), while in the back shot she uses three fingers (thumb, index, and middle). (00:24:55)
Continuity mistake: During and just after the Mulder's seizure, when Scully's face is shown, it is at the level of a standing person which suggests that both agents are standing, but in the next shot Mulder and Scully are crouching. (00:31:35)
Other mistake: When examining the bag via X-ray at the airport, Mulder communicates to Scully that he sees three circular pieces inside, however only one circular piece is visible inside the superstructure. (00:31:20)
Other mistake: The landing plane is shown in a incorrect scale - it's too small compared to the sedans chasing Mulder and Scully. (00:32:30)
Factual error: Gonzales shot himself in the forehead but he's got the back of his head intact - no exit wound. (00:27:40)
Other mistake: Sergeant Louis Frish had not enough time to walk down from the air traffic control tower to meet the agents since he was on the top of it when Mulder and Scully drive up to the tower - two persons can be seen on the top of the tower. (00:21:45)
Factual error: In the background the full moon is visible and it's early morning (approx. 6:00 AM). However, at the start of the episode we see the full moon at night (approx. 19:50). Due to the fact that these are consecutive days, this situation is impossible from an astronomic point of view. (00:14:35)
Factual error: The last number on the truck's license plate is "77." On Russian plates the last two/three digits stand for a registration place. "77" is a number for Moscow, but the Gulag is located in Krasnoyarsk region, so the number should be different. Besides, the format of the plate (LDDDDL|DD) is incorrect - the correct one is LDDDLL|DD (L - letter, D - digit). (00:11:05)
Character mistake: Vassily Peskov speaks Russian with a strong accent. This is because the actor who plays Peskov (Jan Rubes) was from former Czechoslovakia.
Answer: He was being facetious. He doesn't specifically know that information, he was merely giving examples of the types of information he has access to.
I think so too.
