Audio problem: In Fairly Odd Parents, "Switch Glitch", Vicky forced Timmy to do her chores and homework, and stretched a dress on Timmy. He said "I can't do chores in a dress.". Vicky, however, was recording Timmy's voice on a tape, the "in a dress" part, and played the tape, but the tone of voice for "in a dress." was normal, not angry. Shouldn't it be the same?
Character mistake: In 'No Substitute for Crazy", When Timmy and Sanjay are leaving the school after Mr. Crocker falls down the well, a few cats come up to them and he introduced an orange one as "Omar." Later, when Mrs. Sunshine is leaving after being substitute for a day, Sanjay has cats around him and comforts "Omar", except he says this to a red cat, not an orange cat.
Continuity mistake: In 3-8 "The Secret Origin of Denzel Crocker", it showed that Mr. Crocker was 40 years old. (They went back 30 years to his childhood, and he was 10 then.) But in this episode it showed that he was 53 years old. (Everyone aged 50 years, and he was 103. 103-50=53.).
