School of Rock (2003)

Continuity mistake: In the scene where Dewey and Ms. Mullins are in the bar, the shots from behind Ms. Mullins sitting down show that her left hand is on the table. However, the shots showing the front of Ms. Mullins show her arms folded.

Dewey: Billy what makes you angrier than anything in the world?
Billy: You.
Dewey: Billy, we've already told me off, now let's move on.
Billy: You're tacky and I hate you.
Dewey: Ok, you see me after class!

Trivia: The final sequence during the credits was all unscripted. Both the dialog and music solos were improvised.

Question: Perhaps a weird question but why did Patty call the cops when she found out Dewey was posing as Ned? Wasn't that ridiculous since it didn't really seem like too much of a crime - as Dewey said to Patty "it's not like I murdered anybody"?
