This slip-up occurs near the beginning of the movie, right after Josie (Drew Barrymore) tells Rob, (David Arquette, at the Tiki Post, that she is going to be an undercover reporter at high school. Rob reminds her of her nickname "Josie-Grossie" and she proceeds to the bathroom to throw-up. When she flushes the toilet, the flusher thing breaks off. Then as she pulls off the toilet paper, if you look behind her, the flusher thing is connected again. Not a big mistake, but I thought it was interesting.
