One scene shows Senora Gomez breaking the fourth wall, as she says that Austin is "still a junior" while removing her sunglasses and then faces the audience while Dez says, "Who is she talking to?"
At 18:47 minutes, Señora Gomez hands a girl a stick of pink cotton candy, while the cotton candy in the machine is blue. However, in the next shot, the girl walks away with blue cotton candy rather than the pink cotton candy she held prior--clearly a mistake.
According to Austin, his Spanish teacher has the surname Gomez, which is also the surname of former Disney Channel Star Selena Gomez.
