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.
Continuity mistake: Near the end, Gus is standing between the two handball walls. He is looking back at TJ and Lawson, who are near the first wall. But as the camera pans out, TJ and Lawson have moved to the other handball wall.
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 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.
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."
That Stinking Feeling - S3-E11
Factual error: When Lawson catches the ball in the end-zone, you realize he's NOT in the end-zone.
Other mistake: When the gang enters the Ashley's Clubhouse and catches the Ashleys and Randall taking the treasure, Ashley B's skirt is incorrectly coloured green. A second later, it is yellow again as it should be.
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.
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: The Library Kid says her classmates were savages. This is all well and good, except the kindergartners shown are the present day kindergartners.
