Continuity mistake: When Lizzie and Miranda walk over to the table which Gordo is standing on top of (as he sells his pudding cup) in one shot Miranda puts her lunch tray on the table and her hands are empty in the next shot. But in the following shot the tray is suddenly in her hands again.
Continuity mistake: When Gordo hands Lizzie his 'flier' which promotes his tutoring service, in this shot we can see that the whole edge of the paper (including the perforated margin) is completely intact. But in the next shot half of the margin is missing (torn off) which then appears again in the next.
Continuity mistake: When Lizzie and Miranda are pushing their table closer to the one that Gordo and Ethan are sitting at, they eventually knock the tables into one another, causing everything to tip over, including their two drinks. Between shots the arrangement of the items over the tables changes and the two drinks glasses disappear as well.
