The New Kid - S1-E2
Other mistake: At the start when the gang change the time on the clock in the classroom, it wouldn't control the main school clock, plus in every other episode the clock has been operated by The Box on the side of the school, as shown in " The spy who came into the playground".
Other mistake: In the episode, "the peanut butter kid", he is always eating his sandwich and it always seems like he only took a bite out of it and sometimes it went all the way back to the top. How could that be, he couldn't be chewing the entire time.
I Will Kick No More Forever - S1-E11
Other mistake: When the gang go to visit vince in his house, it shows vince watching a video of a kickball game. but kids most definitely wouldn't be able to bring a video camera in to school, and it most probably would be confiscated by miss finster.
