Corrected entry: When Jimmy and Brad are talking to Emma (the deaf girl) near the end of the episode, Brad translates Emma's sign language for Jimmy, but when Jimmy talks, Brad makes no hand signs for Emma. Therefore, she shouldn't be able to understand what Jimmy is saying, yet she replies. She can't be lip-reading, or else she would have understood what Lily or Henry was saying upstairs in Jimmy's room (you could see from her reactions that she didn't understand either of them).

Oops!...I Did It Again - S2-E22
Continuity mistake: This episode establishes that Lily was born at the Live Aid event, which took place in July 1985. In the show's final episode, "Hello, Goodbye", Brad and Lily are graduating in 2005 (see the "congratulations" banner in a hallway at their school). Being born in 1985 would mean that she is graduating at age 20. It is highly unlikely that she failed and repeated two of her school years. Brad, who is the same age, is graduating with her, and he is a dedicated student.
Henry Finnerty: Wow, that ride must be really scary. Those two guys are holding hands.
James "Jimmy" Finnerty: That's the line for cotton candy.
Trivia: Megyn Price plays Claudia Finnerty, mother of Lily Finnerty (Lynsey Bartilson). In real life, Price is only 12 years older than Bartilson.
Jimmy Was Kung-Fu Fighting - S1-E12
Question: How can Sister Helen give Lily detention when she sees Lily's tongue ring? She is at the Finnerty's house. Piercings are often a violation of school dress codes, but Sister Helen has not seen the piercing while at school.
Answer: It happens. One of my middle school/junior high classmates was suspended for fighting another classmate during the weekend, at a location nowhere near the school. Also, after Jimmy and Lily created the fake image of Sister Helen, it's easier for Sister Helen to get away with assigning an unfair detention.
Correction: Jimmy was speaking slowly and saying it so she could easily read his lips, Lily and Henry were talking to fast for her.
