Other mistake: When Gretchen tells Mikey, "I'd be happy to help with matters of enunciation and syntax, of course," the soles of Gretchen's shoes are brown, as they should be, but then they turn white mid-shot. The next time we see Gretchen, they are brown again.
The New Kid - S1-E2
Continuity mistake: In the beginning, after the kids have gone to recess, Vince starts talking to TJ about Gus. The number of bricks between the windows on the wall behind them and the bricks' position changes four times.
Theodore J. 'T.J.' Detweiler: Never kid a kid who hasn't had his recess.
Trivia: The J in T.J. stands for Jasper.
