Other mistake: When the court hearing is taking place, T.J. wears a tie with blue and red stripes. As T.J. says to the mayor, "Sorry, sir, may I say something?", the stripes on his tie change to the opposite color for one frame (not counting the stripes on the knot).
Other mistake: When the Ashleys are playing jacks, Ashley B is wearing her usual yellow sweater, but in the next shot, it becomes red, the wrong colour. It goes back to yellow in the next shot.
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.
