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.
Continuity mistake: In the introduction, when TJ pulls the ball off Gus, Gus is covered in gum. When they are walking into the school, the gum has disappeared.
Theodore J. 'T.J.' Detweiler: Never kid a kid who hasn't had his recess.
Trivia: The J in T.J. stands for Jasper.
