When the lunch lady says, "garlic bread, Stinky?", her mouth doesn't move.
In the lunch line beside Brainy, Joey has the same blue pants white shirt outfit as Eugene (minus the underwear) and even has the same orange hair color and white skin as Eugene.
At lunch, both Harold's shirt and arm are shown to be different colors than what they are. Harold's shirt is a different skin tone, and his shirt is shown green with a red stripe on the sleeve. In the same scene Eugene is shown without his socks and Lorenzo is off model.
In this episode, the City Library is painted red instead of yellow.
