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: During Sam and Freddie's first interaction, Sam can be seen holding a coffee cup when she enters the room.

A green logo on the cup is plainly visible.

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.

Continuity mistake: When they have the first meeting with the techfoot people, Sam is eating a sandwich. Every time the shot goes back to her and Carly, the amount of the sandwich she has eaten changes. Sometimes there is a bite taken, and then the next time there isn't a bite taken out of it.
