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.
Plot hole: Why did Mikey jump to make the feathers fly if Vince said to abort? When TJ gets hit by the feathers, he's on the 'X marks the spot.' But when he got honeyed, he was nowhere near it. Before TJ gets feathered, He gets up onto his feet, like he had fallen down. But he was still standing when Mikey fired the feathers.
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."
The Great Jungle Gym Stand Off - S1-E21
Other mistake: When TJ says that he and the rest of the gang met at old rusty, it shows you a flashback and the kindergartners are wild, but they only became wild when Gus arrives later (as said in All Growed Down).
Suggested correction: It's not true. After Gus "changed" the kindergartners he was sent away from school.
This correction misses the point of the mistake. In "Recess: All Growed Down," when Gus moves to the school, the kindergartners are shown as "normal," but then Gus changes them to be wild, and they start to have torn clothes and paint on them. However, in the flashback scene in this episode, it shows the gang meeting on the first day (excluding Gus), and they have torn clothes and paint on them. This doesn't make sense because they only became that way when Gus moved to the school.
Revealing mistake: Right after TJ and friends are looking at the "thermometers" of cans, the Ashleys have at least 4 crates of cans that they bring in on forklifts. However, the end result is 4,362 cans for the Ashleys. This may seem kind of picky, but I think there was more cans than 4,362.
Suggested correction: This is literally just an assumption, and nothing else. 4,362 is a pretty huge number, and with the amount of cans that we see the Ashleys collect in the episode, combined with the amount of cans that they and the rest of Miss Furley's class collected off-screen, it is perfectly believable that Miss Furley's class would end up collecting that amount of cans.
Continuity mistake: In the beginning, Gretchen says she's short on money, so she can't get a chocolate milk, just a white milk. But, when T.J. walks by with his food, Gretchen has a chocolate milk, such is evident from the brown carton.
Suggested correction: Gretchen tells the lunch lady that because she is one penny short, she will swap the chocolate milk (in her hand) for a regular. She puts the milk on her tray and walks off screen. Then, when T.J. walks past her, the camera pans over to Gretchen watching T.J. with that same chocolate milk on her tray she is holding. Gretchen got distracted by T.J.'s encounter with the lunch lady and stopped to watch him, but she was still going to swap the chocolate milk for a regular later on.
Factual error: When Menlo is hoppin' scotch, he lands on 10 with both feet, and 10 is a single square.
Suggested correction: He does, but this is simply a mistake Menlo makes as a character. And it is not a 'character mistake'; I can see many people making a very simple mistake like this while playing hopscotch. I know I probably have as a kid. Also, he lands on an 8 square, not a 10 square.
