Other mistake: After Dave takes away Mikey's lunch tray, it fades to a shot of the school clock, and there is no 5 on it.
Continuity mistake: When TJ is in The Box, he lays down and puts his head on his baseball glove. Then when he gets up, he doesn't pick it up, but it's nowhere to be seen. Then a couple of shots later, it's back, and it's on the other end.
Factual error: At the end when Ms. Finster tells Randall to give her the names of the kids involved with the ball incident, she says to list them in alphabetical order. The first name Randall says is "Dettweiler, T.J." But "Blumberg, Mikey" would actually come before that, and given what we know of Randall, this isn't the kind of mistake he is likely to make.
The New Kid - S1-E2
Continuity mistake: In the beginning, as Gus' dad walks away, the lights on the ceiling are 3 tiles apart. However, while Gus is describing his "personal journey," the lights are two tiles apart.
Continuity mistake: In this episode, it shows Randall in Miss Grotke's class, but in every other episode, it's never shown him in there.
Audio problem: When Tubby is about to win the race, Mikey shouts "Run Tubby run" in Spinelli's voice.
Suggested correction: Not really. It definitely sounds like Spinelli due to how he screams the line, but it's not Spinelli's voice. Something similar happens a moment earlier in the episode, when Mikey screams, "Win, win, win!" His voice gets a bit raspy, similar to Spinelli's raspy voice, but those aren't the same voices. Also, I don't know why they would have Pamela Adlon (Spinelli's voice actor) record that one line for Mikey anyway.
Continuity mistake: When the Diggers lift the treasure out of the hole, there is a lock on one side of it. Three shots later, the lock had moved to the opposite side of the treasure chest. The lock then vanishes and reappears in the following shots.
Continuity mistake: After Mikey pours dirt into the hole, he holds the bucket in his right hand, but it disappears in the next shot.
Continuity mistake: When Vince and Spinelli are talking in front of the bathroom doors, when Spinelli says, "How about you and me sneak out... just the two of us," the push plate is missing from the boys' bathroom door, then it reappears a shot later.
Other mistake: When Spinelli tells Gretchen, "Gretchen, what colour is the sky in your world?", Spinelli's neck clips through her dress collar twice.
Continuity mistake: When Gretchen leaves the school building at the end, she leaves the doors open behind her, but when she catches the helmet that Spinelli throws to her, the doors are suddenly closed.
Other mistake: When Gretchen is in Kelso's Corner Store, Mr. Kelso tells her that if she thinks she got the money in the wrong way, she should just give it back. In this shot, part of Mr. Kelso's shirt collar is incorrectly coloured red; then it changes to its proper tan colour mid-shot.
Other mistake: When Gretchen enters Kelso's Corner Store, the blue and yellow bicycles are slightly cut off at the bottom of the screen.
Continuity mistake: After Miss Grotke writes "The Zen of Homework" on the chalkboard, she holds the chalk in her right hand, but it disappears in the next shot.
Continuity mistake: At the start, when T.J. tells Gretchen to save up her allowance so she can buy Ruddler's Red Rocket, Gretchen's helmet strap has vanished; then it reappears a shot later.
That Stinking Feeling - S3-E11
Other mistake: After Gretchen's Galileo says that Spinelli has a crush on Johnny V, T.J. puts his right hand behind Vince's neck, and his hand and cuff disappear mid-shot. (00:05:21)
That Stinking Feeling - S3-E11
Continuity mistake: When Spinelli's father is first shown watching TV, there is no ring on his left hand, but one appears on his ring finger in the next shot. The ring then vanishes and reappears in the following shots. (00:03:32)
Continuity mistake: After getting off the school bus, when Gus falls into the hole that Sam has dug in front of the school, he's wearing his watch as usual. As Gus sits up, his watch vanishes mid-shot; then it reappears on his wrist.
Continuity mistake: After Upside-Down Girl tells TJ he must do something about Dave, when the gang look for Sam and discuss the situation with him, the clock over the school doors repeatedly changes time between shots. Then, when Sam grabs the shovel and jumps back into the hole, the two hands of the clock vanish, only to reappear and change time yet again.
Other mistake: At lunch, when Sam is using a spoon to shape his mashed potatoes on the tray, his right arm clips through the tray just as he says, "Maybe I should clear out the east wall like this." Then, when Sam says, "Maybe I should fortify the south side first," he's using the spoon to move the mashed potatoes on top of the tray, but his arm and spoon are under the tray, so it looks as if the potatoes move on their own. Additionally, when Sam states that he's so confused, the spoon held up in his right hand appears to vanish in the next shot.
