Ricky Asks For a Raise - S1-E35
Character mistake: After Tropicana nightclub owner Mr. Littlefield replaces Ricky Ricardo with Xavier Valdez, "the Konga King," Lucy, Fred and Ethel try to get Ricky's job back by going to the nightclub in a succession of different wigs and costumes, then leaving when they learn that Ricky is no longer performing there. At one point, Fred and Ethel enter the nightclub, posing as "Mr. And Mrs. Crumley." A disguised Lucy enters one minute later and is outraged to hear that Ricky is no longer there. Ethel then pretends to phone a friend to tell her to not come to the nightclub. Lucy says, "Attagirl, Mrs. Crumley." However, when Ethel had told the maitre d' she had a reservation for "Crumley," Lucy had not yet entered and therefore should not have known that name.
Suggested correction: During the point when Mrs. Crumbley wants to call her friend to get her friend to cancel her reservations as well, Mr. Littlefield says, "But Mrs. Crumbley," to protest as she walks to the phone to make her call. So he did say her name in front of Lucy, thus giving her the name to reply with, "Attagirl, Mrs. Crumbley."
The Blood of a Jeannie - S5-E7
Character mistake: Jeannie tells Tony that she can't blink, then immediately blinks.
On The Lam / Family Man - S5-E17
Character mistake: In the wrestling match, the bell rings after the referee counts to 3 - but he's counting while a wrestler is on the mat stomach-first; a pin requires the loser to be on his back.
Family in Paradise: Part 1 - S4-E25
Character mistake: The hunky male tour guide compliments Cissy on her brown hair when she's an obvious redhead.
Character mistake: Season 3, Episode 2 "Squirmy". Little Bill and his brother, Bobby are returning his pet earthworm to the soil. Bill calls his brother by the name Jamal. Jamal is Little Bill's baby cousin.
The Tale of the Manaha - S5-E7
Character mistake: Near the beginning as the leader is about to set off with the boys, he says, "About face!" and turns to the left, and the boys follow suit. But "About face" means to turn 180°. He should have said "Left face" to get them to turn 90° to the left. (00:04:25)
School Elections & Talent Show - S1-E8
Character mistake: There is a campaign poster that reads, "Vote for Ned or Your Dead." "Your" should be spelled "You're."
Character mistake: In the Armchair Theatre story, Billy mentions that the grandma puts a tray of chocolate brownies into the oven. In the next scene the grandma (played by Billy Butler) has a tray of cookies, not brownies.
Character mistake: When Geoffrey serves tea after his sassy cough at Vivian's sentence about High Tea not being a sacred institution, the actor messes up when it's time to actually serve tea, with a napkin getting caught in the teacup saucer. Granted, accidents do happen, but it's quite uncharacteristic for the perfect butler Geoffrey is portrayed to be, and simply a flub by Joseph Marcell. (00:17:45)
Character mistake: Jessie's dance moves don't match what the other girls are performing, even though it's a choreographed routine.
Spider Wars, Chapter 1: I Really, Really Hate Clones - S5-E12
Character mistake: When the group of Spider-Men are breaking into the Kingpin's building through the front door, Octo-Spidey uses a laser to cut a circle in the door and then proceeds to tear the door off its hinges with his robotic arms. Since he was just able to simply tear the door off, there was no need for him to cut the hole in the door in the first place. It's not like he needed to reach through the hole with one of the arms to unlock it from the other side.
Character mistake: Dr Smith who has some of The Robot (ie, bravery and courage) quotes The Fall of The Light Brigade but mistakenly says "into the valley death rode the five hundred" when it is actually 600. Both Dr Smith and the Robot would know this very famous poem's most well known line. (00:44:45)
Suggested correction: There's nothing to suggest they would know the poem exactly, especially since you yourself don't even know the actual name of the poem. It's "The Charge of the Light Brigade."
The Hairy Scare of the Devil Bear - S1-E8
Character mistake: Velma says bears only have four claws. Wrong, they really do have five claws.
Character mistake: When we first meet Gadus, he pronounces his name "Gay-dus", but later on in the episode Maran calls him "Gad-us".
Character mistake: Dexter's father says he'll stunt jump over four school buses, but only three are shown.
Character mistake: Micah is clean-shaven but he enters the barber shop and asks for a shave.
A Frightened Hound Meets Demons Underground - S1-E14
Character mistake: Velma mentions Seattle burned down in 1890. The fire went from June 6-June 7 1889.
Timmy the Barbarian/No Substitute for Crazy - S5-E18
Character mistake: In 'No Substitute for Crazy", When Timmy and Sanjay are leaving the school after Mr. Crocker falls down the well, a few cats come up to them and he introduced an orange one as "Omar." Later, when Mrs. Sunshine is leaving after being substitute for a day, Sanjay has cats around him and comforts "Omar", except he says this to a red cat, not an orange cat.
Burple Nurples/Shnitzel Makes a Deposit - S1-E2
Character mistake: In "Burple Nurples", Chowder was selling Burple Nurples for 5 dollops each. Later, Mung Daal steals a tray of six Burple Nurples, and Chowder runs after him, telling him that he owes him 300 dollops, instead of 30.
Suggested correction: The tray had more than 6, even if it was drawn to look like just 6, they could have been stacked on top of each other. Later when they're dumped in the fire, you can see more than 6 go in. Plus at that point we don't know how much Chowder was selling them for since it was after Mung Daal (while in disguise) paid more than 5 dollops for one.
Cat on a Hot Steel Beam - S1-E60
Character mistake: As the fire truck darts out from a back alley, the sign on a nearby gift shop window reads "gift's" when it should be "gifts".
