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.
