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.
Continuity mistake: When Spinelli arrives at school at the end, she holds her purse in her hand, but it disappears two shots later. It reappears when the gang starts to play tag.
Other mistake: When Spinelli sees the man walking multiple dogs, as she asks him how much he gets paid to do it, the poodle's chest fur becomes the same colour as the background twice in two frames. The same thing happens with one of the Dalmatian's legs.
Continuity mistake: When Spinelli and Pat Patterson sit on the bus bench, the text on the bench that says "Just Buy It" has a period at the end, but the period is missing in all the following shots.
Continuity mistake: When Pat Patterson tells Spinelli that they should have a seat on the bus bench, the bench is missing the word "Gumoflex" and the black gum logo that it had in a previous shot. They both reappear when Spinelli and Pat sit on the bench.
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
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)
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
Factual error: When Lawson catches the ball in the end-zone, you realize he's NOT in the end-zone.
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: 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.
