Continuity mistake: When The Library Kid speaks for the first time, you see a shot of the gang, T.J's hat and hair colour are mixed up.
Character mistake: When Mikey looks at the Picture Day schedule, he points out that 4th grade is going last. However, the schedule says they are after 3rd grade and before 5th grade, actually making them fifth. The faculty is actually listed last on the schedule.
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.
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)
The Shiner - S3-E9
Factual error: In the beginning, right before the class is noticing TJ's shiner, Ms. Grotke says, "Abraham Lincoln, the 16th President..." which is true, but on the poster behind her, it says "Abraham Lincoln, 14th President."
Suggested correction: Incorrect. The poster correctly reads, "Abraham Lincoln, 16th President."
Continuity mistake: When Library Kid sees her kindergarten class, she's wearing a dress, but when she runs into the library, she's wearing a T-shirt and skirt.
Continuity mistake: When Menlo tells the crew about Randall's joke book, he loosens his tie, and it's still loose when he says "Indeed." But half-a-second later, as he walks away, his tie is back to normal.
Other mistake: The Diggers start digging a hole in the Ashleys' clubhouse, then it cuts to a shot of Gus pouring out the dirt. In this shot, there is a circular object on the roof of the cafeteria building (presumably a satellite dish) that has been left uncoloured.
Continuity mistake: When the Diggers lift the treasure out of the hole, the handles on the sides of it are yellow. Then, when the kids start fighting over the treasure, the handles change to gray; then they are yellow again after Gretchen finishes reading the note.
Character mistake: Gretchen finds a note on the lid of the treasure chest and reads it. We see a close-up of the note in her hands. The problem is that what Gretchen reads is not entirely accurate to what is on the note, and the whole last half of what she reads is not even written on the note; it gets cut off at the bottom.
Other mistake: After the kids start fighting over the treasure, T.J. gives a speech to them. Then, when it cuts back to the other kids, Ashley T's socks are mistakenly coloured the same as her skin instead of green, as they should be. This error is shown again in the shot after the kids drop the treasure chest.
Other mistake: When the gang catches the Ashleys and Randall taking the treasure in the Ashleys' clubhouse, in the shot after Spinelli says, "Since when is Randall an Ashley?", the lines on the wall are mistakenly drawn over the plant in the background.
Continuity mistake: After the scene of Vince and Spinelli talking in front of the bathroom doors, it cuts to kids leaving the school, and the doors are left open after they all leave. Two shots later, they are suddenly closed. Doorknobs also appear on the doors, which weren't there before.
Continuity mistake: After the scene of Vince and Spinelli talking in front of the bathroom doors, it cuts to kids leaving the school, and Gretchen has her backpack on. In the next shot, it vanishes.
Other mistake: When Miss Finster drinks the cup of dirt and spits it out, her waistband is mistakenly coloured grey. Then, when we see her again a moment later, it is white again as it should be.
Other mistake: When we first see the gang inside the Ashley's clubhouse, in the shot after T.J. says, "Ladies, you have a deal," there is a big white line at the bottom of the screen behind the characters; the background seems to have been shifted up slightly in this shot.
