Continuity mistake: There is a scene where the iCarly gang are arguing with Nevel. Sam went to beat Nevel up, which during the process made her hair messy and her headband slipped backwards. However, in the next shot her hair is not messy and her headband is perfectly normal. This keeps happening several times throughout the scene.
Continuity mistake: When Spencer first gets his Galaxy Wars thing, it doesn't show the sticker that says it is not a real prop from Galaxy Wars until Freddie tells Spencer.
IMeet Fred - S2-E10
Character mistake: Carly says Shelby, ID Is 4 hrs away. It's more like 11 and a half hours from Seattle.
Continuity mistake: Sam fights Freddie about a bikini. When he wins he throws it down. After the fight, there is a close up of him. You can see a flag in the window of the door. Then two girls walk up. In the next close up, the flag is not there.
Revealing mistake: During the shot where Chuck flips Spencer for a brief second you can see his face, which reveals that it's a stuntman as he is a different person.
Other mistake: At the beginning, when everyone is watching Shelby fighting on TV, the timer is going too slow. According to the timer, the fight ends at 2:53, which is only 7 seconds of fighting, yet the fight was way longer than that.
Continuity mistake: In the beginning, Carly gets a bowl and fills it with popcorn up to about 2/3 full. The camera cuts to Sam, then back to Carly, and the bowl is barely full. The camera goes back to Sam then to Carly again, and the bowl is 2/3 full again. Freddie walks in, and the bowl is barely full again, which Carly now fills with popcorn.
Revealing mistake: Carly, Sam and Shelby all corner Nevel in the ring. If you look in the corner where Shelby shows up, she's not in that corner until the light flashes on her.
Continuity mistake: When the gang is at their apartment watching the news over how they think Carly pushed Shelby's grandmother down, there is a ladder outside their door that appears and disappears from shot to shot.
Continuity mistake: When Freddie wrestles Carly to the floor, there are three shots of her lying on the floor as they argue. The first two show her head in the same spot on the floor; the third shows her head in an entirely different spot (look at the floorboards).
Plot hole: Near the end, Sam locks Mr. Howard and Ms. Briggs in a closet. Sam and Gibby then put a heavy desk right against the door and leave them stuck inside. Then later the two teachers are seen frantically controlling the students. How did they escape? They were inside a closet with the door locked on the outside and with a heavy desk against it.
Suggested correction: It's clear that another teacher or teachers heard the announcement or heard them yelling and let them out... What we should be asking is why no other teachers helped them control to the students.
IQuit iCarly - S3-E8
Continuity mistake: Carly, Sam, Fleck and Dave are sitting at one table at the Groovy Smoothy sipping a new smoothy flavor with T-Bo standing next to them. Suddenly the smoothy gets too spicy so all four go to another table and gulp down other people's waters then sit back down. The waiter places two glasses in front of Dave and Fleck. The waiter starts to pass behind T-Bo with 2 more glasses of water, but the shot immediately cuts to Sam and Carly drinking water.
Revealing mistake: After Sam shoots Spencer with her blowgun, she lands on the ground after jumping from the ceiling. During this shot, you can easily see that it is a stunt double.
Continuity mistake: When Sam, Carly, and Ernie the dance coach are backstage hearing about the talent competition, his hands and clipboard move position from shot to shot.
Character mistake: Sam says that "Ginger Fox USED to be good; then she hopped onto the crazy train and ended up on has-been island," (or something of that sort). Freddie then says that "technically, you can't take a train to an island, because they are surrounded by water." This is untrue, because technically, Manhattan is also an island, and there are MANY trains that go to and from this island.
Continuity mistake: When Ginger Fox and her manager are in her room, Ginger squats down to tell her rabbit to roll over. Her bra strap has slipped off her shoulder. When the camera pans out, her bra strap is up. The camera zooms back in to her face, and her bra strap is down again.
Continuity mistake: After Gibby is kicked into the stack of boxes, he slumps to the floor and a large sleeping bag or pillow appears beside him only to disappear in the following scene. Then when he takes off his shirt, a yellow extension cord appears on top of the boxes.
Continuity mistake: An unconscious Nora falls to the floor, her head landing squarely in the center of a white tile. But in the subsequent closeup, her head is on a grey tile.
Continuity mistake: When the iCarly gang and T-Bo rush in to set up the birthday breakfast for Carly, the balloons change positions between shots.
ISam's Mom - S4-E2
Continuity mistake: When Sam breaks into Carly's room, Carly wakes up and her hair is messy. In the next shot it is less messy and in the shot after that it is perfect. In the shots after that her hair becomes more messy.
