Continuity mistake: Sam hires a personal chef, Sonia. When Carly, Sam and Freddie are sitting at the table and Spencer is talking to them, Sonia takes the blueberry muffins out of the oven and puts her oven mitts down. Next, Spencer starts walking away. Then Sonia is putting down her oven mitts again. There is no way she could pick up and put down her oven mitts that fast. (00:13:15)

Continuity mistake: Spencer arrives at his destination with butter on his elbow but it disappears a few moments later.
Continuity mistake: During Sam and Freddie's first interaction, Sam can be seen holding a coffee cup when she enters the room. For the first half of the conversation the cup is plain white, but as the camera returns to Sam, and she says, "You mean I can't play with the white balance on your super-dee duper-ee camcorder?" A green logo on the cup is plainly visible.
Continuity mistake: In episode 3 of Season 1 we see Sam smashing the locker next to Carly's as she thinks it is hers. Gibby comes up to her and says that it's his locker and hers is the one on the right - which she promptly unlocks. However, in the next episode (ILike Jake) the start of the episode features a gag where Sam has traded lockers with Arthur Gradstein, to be next to Carly's locker as her locker is in between two sweaty aggressive football players, however in the previous episode she was seen unlocking the same locker that she apparently just traded with Arthur, after smashing Gibby's locker that is in the middle to pieces.
Continuity mistake: When Carly and Sam are on the web show at the beginning, Sam puts the air hose around the edge of the watermelon. When the camera cuts back to the watermelon later on, the air hose is in the center of the watermelon.

Continuity mistake: The locker that Sam has is introduced here, but in episode 3, she already has that locker.
Suggested correction: That's because the episodes were aired out of order, which isn't a mistake of the show. Episode 4, "ILike Jake", was the 2nd episode produced and episode 3, "IDream of Dance", was the 13th episode produced.
Continuity mistake: Sam pushes Freddie into the "haunted" apartment. In the very next shot, from inside the apartment, Freddie is standing up. In the next shot, outside the apartment, Sam is pushing the cart with Freddie's equipment on it and Freddie's voice says something like, "Ow! Quit it, Sam!" as if he is still lying on the floor. In the next shot, back inside the apartment, Freddie is standing up again.
