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: 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.
Continuity mistake: Spencer arrives at his destination with butter on his elbow but it disappears a few moments later.
Other mistake: When Carly and Sam are pumping the watermelon full of air, one shot zooms in on Carly's finger as she hits the on-switch. The device is turned off as she removes her finger. (00:01:32)
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: 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.
Character mistake: Freddie mentions that they had an audience of 355k which was the most they've ever got. But in the earlier episode of ISpy a Mean Teacher, they had an audience of over 500k.
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.
Revealing mistake: When Carly's in her dream and attempts to use the elevator, if you look really closely, she doesn't actually hit the button that lights up.
ILike Jake - S1-E4
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.
