IWanna Stay with Spencer - S1-E5
Revealing mistake: When Spencer turns on his iPod when talking to his Grandpa, you can see that the headphones are not plugged into the iPod.
Suggested correction: It is plugged in, but the cord runs from Spencer's head under his shirt and meets the iPod near where Spencer's green short sleeve shirt meets his long sleeve white sleeve shirt. Only a very short bit of the cord appears from under Spencer's sleeve to the iPod strapped to his arm.
Continuity mistake: In "iGetPranky", when Carly and Spencer begin talking, Carly turns off the TV before they start talking. Then she turns off the TV once again.
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.
Continuity mistake: When Freddie first tests Sam's emotion with "MoodFace," IN LOVE is written in red. Later, when he shows the results to Carly, IN LOVE is written in green.
Continuity mistake: Spencer is talking to the Sunshine girls about stealing his spot. After he gets pushed in the street, when his skateboard goes flying and breaks in two, one half goes offscreen, and one goes under the table. In the next shot both halves are by his feet, but in the next shot they are back in their original positions.
Character mistake: The girl Spencer dates does not speak Uzbek, she speaks Russian.
Continuity mistake: When Sam bangs on the locker with the hammer, the amount of damage on the metal repeatedly changes; it decreases, increases, decreases, and so on.
Continuity mistake: When Spencer and Carly are blowing bubbles to the ceiling, when the bubbles pop, and the soap comes down, Carly's hair is all knotted and messed up. But when she sits up, her hair is perfectly parted and straight.
Continuity mistake: When Lewbert is on the ground and everyone's in the lobby, you can see that Carly's shoe doesn't have a large wart before Lewbert screams, "Where's my wart!"
Other mistake: There is an A stuck to Carly's butt, but nothing touched Carly's butt when she got downstairs. (00:20:30)
Factual error: "IParty with Victorious" is shown after the episode "iOMG". The thing is, anything that happened in "iOMG" never happened in the episode "IParty with Victorious". "IParty with Victorious" should have been shown first, not "iOMG".
IParty with Victorious - S4-E10
Continuity mistake: When Sinjin is on the game that malfunctions, he flies out the window. Before he hits the window he's facing up; when he's about to hit the pool, he's facing down.
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).
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 Mrs. Benson walks into Carly's apartment holding the clothes she picked out for Freddie, the clothing repeatedly turns around in her arms and also when she places them on the counter.
Visible crew/equipment: When Spencer is replacing Lewbert, you can see the studio lights reflecting off the bronze dome.
Continuity mistake: Carly and Sam stick their heads in buckets of water to stay awake. Their heads and clothes are wet during the whole scene, but when the show comes back from commercial, their hair and clothes are completely dry.
