Corrected entry: In the sewer, the guy with the big forehead starts singing with his guitar and a crowd gathers around. But you can see Leela's parents standing in the crowd and having no reaction to their daughter whatsoever, despite them knowing what she looks like. Considering later episodes, this is a bit confusing.
Roswell That Ends Well - S4-E1
Corrected entry: The sergeant refers to Fry's grandfather Enos by his first name, something that would never happen. A superior officer - especially a non-com - would refer to him as "Fry", "Private" or "Private Fry". No army sergeant ever referred to an enlisted man by his first name.
Correction: You've clearly never been in the military. First names and nicknames will get used, especially if they are unusual.
Correction: A Sergeant is not an officer, he is enlisted just like the privates. The one in question was probably an E6 or E7.
A Big Piece of Garbage - S1-E8
Corrected entry: When Fry, Lela and Bender are on the big ball of garbage, Bender picks up a Bart Simpson doll, pulls the cord on its back and the doll then says "Eat my shorts". The batteries should have gone flat by the year 3000.
Correction: Dolls that have a pull cord like that don't use batteries.
Kif Gets Knocked Up a Notch - S5-E5
Corrected entry: When they are all in the thing that spins them around to see who will be the father/mother of the baby, Zoidberg is not in the machine, but somehow he flies out.
Correction: This is explained very clearly in the episode. When Zoidberg is ejected the Professor asks him what he was doing in there and Zoidberg answers: "That's where I live. I have no home." So Zoidberg was already in the machine before the others enter. (Probably hiding under the grated floor.)
How Hermes Requisitioned His Groove Back - S2-E14
Corrected entry: This has to be done in slow-motion to actually notice. When Morgan and Hermes first meet they give each other a paper to stamp. It's already been established that a bureaucrat stamps forms five times, but, if you watch the scene in slow-motion, when Hermes gives Morgan a form to stamp and Morgan gives Hermes a form to stamp, Hermes stamps the form he was given 3 times and Morgan stamps the form she was given 2 times. Then when Hermes gives Morgan back her own form and Morgan gives Hermes his own form, Hermes stamps his own form twice and Morgan stamps her own form once. They both should have stamped both forms five times.
Correction: The rules of this site are quite clear - if you have to use slow motion or freeze frame to spot a mistake, it is not valid.
Episode Two: The Series Has Landed - S1-E2
Corrected entry: The part of the Lunar Module that Fry and Leela go inside shouldn't be there, the astronauts would of used it to get back to the CSM orbiting the moon. The whole thing lands on the moon but the cabin, the bit where they go in, should actually be floating in space somewhere after they had jettisoned it.
Correction: This is explained in the episode. When Amy shows up with the Planet Express Ship, right after Fry says "It's Amy, we're saved", you can see a plaque inside the module with the text "Lander returned to this site by the Historical Sticklers Society". So no mistake here.
Corrected entry: In this episode, no one can read the Alien language on the note left by Leela's parents. However, this language has been posted on various signs throughout the series. It would be rather pointless for someone to make advertisements that no one can read.
Correction: How do we know it is the same language? Just becaus it uses the same alphabet, it doesn't mean it is the same language. E.g. French, German, English, Welsh, Spanish, Italian all use the same alphabet.
Corrected entry: Just after the turn of the millennium into 2000, Fry falls back into the space capsule set for exactly 1000 years. So why does he wake in 2999, a few hours before the year 3000?
Correction: Because there are not exactly 24 hours in a day. The computer in the capsule is set to exactly 1000 years. Alternatively, the city was destroyed several times as you can see in the background, so there may have been numerous power fluctuations.
His building would certainly have been destroyed as well.
Corrected entry: In the final part of the "tear-jerker" sequence at the end, the pizza shop owner is seen to be elderly and walking with a stick. The sequence starts the day after Fry was frozen (when the pizza shop owner appeared to be middle aged) and is only supposed to last 12 years - the pizza shop owner ages too fast.
Correction: We don't know how old he is to begin with, or what illnesses he has suffered from over the years. He may have been 60 to start with, and there is a quite significant change in most people between 60 and 72. He may have been in a car crash, developed a debilitating disease, anything.
True, and in Bender's Big Score, he is in a wheelchair and coughing by 2010.
Corrected entry: In this episode, robot homosexuals are referred to as "romos". However, in the first episode, it's referred to as "robosexuals", so that would logically mean that it could be cut down to "robos", so why does a robo suddenly mean a robot hobo?
Corrected entry: Zoidberg said here that he has three hearts, but in the Roswell episode he said he had four.
Correction: Zoidberg tells the US soldiers that they can "keep it (the heart they pull out during the autopsy), I've got three more", so he did have four, but lost one for good.
Xmas Story - S2-E8
Corrected entry: Professor Farnsworth says pine trees have been extinct for 800 years, yet they are shown in at least 3 previous scenes.
Correction: Those are fake pine trees. They fold down to be easier for skiers.
Corrected entry: At the end of the sequence of flashbacks, Seymour knows exactly where Fry is and that he is trapped, and just the day before was attempting to lead people to that location. Why would he suddenly give up and do nothing for 12 years?
Anthology of Interest 2 - S4-E3
Corrected entry: When the toast pops out of the 'raccoon toaster' it is regular shaped bread, but when Fry holds out the slice he has bitten it has a distinct T shape. The shape of the bite Fry took out changes, too.
Correction: The bread/toast is upside-down in the toaster, as evidenced the the fact that Fry grabs the bread, and immediately puts it to his mouth - holding it by the bottom of the slice, and biting the T-shaped side.
Corrected entry: Professor Farnsworth addresses the crew, saying that someone has taken the time button and is pressing it every 10 seconds. But how would he know, since he wasn't around the time button zone to bypass the loop? (00:10:20)
Correction: The professor was inside the time shelter, so he was protected from the time loop when the button was pressed, so he could physically see time looping again and again.
Corrected entry: When Leela lifts Lucy Liu's jar off the pedestal, the pressure sensor alarm goes off. But then she puts Madeline Albright's jar on Lucy's pedestal to silence the alarm, and the alarm on Albright's pedestal didn't sound.
Correction: It is mentioned that there are extra security features for their more "valuable" celebrities.
Why Must I Be a Crustacean in Love - S2-E9
Corrected entry: When Fry says he'll lend Zoidberg his arm, he holds it up. It has the right hand, but bends like the left arm.
Correction: It's definitely bending like a right arm would.
Why Must I Be a Crustacean in Love - S2-E9
Corrected entry: When Zoidberg cuts off Fry's right arm, it changes to a left arm lying on the ground.
Corrected entry: The dipstick Leela pulls out of the Planet express ship stairs is significantly bigger than the stairs. (00:01:00)
Correction: There is no error, it's done for comedic effect. It's a play on Doctor Who's TARDIS, which is bigger on the inside.
Corrected entry: When Fry and Bender are in the Suicide Booth together, Fry understandably dodges the cutting implements that the booth attacks with. However, Bender did actually want to die, so why would Bender dodge them too?
Correction: This is not a mistake. At this point in the series, Leela's parents are still trying to keep their distance, and not let anyone know that Leela is a mutant.
