Factual error: In the movie, prom happens during the end of the film. The movie spans the length of a week, yet we see that Jessica's boyfriend in the movie (Matthew Lawrence) is still having football practice. The high school football season ends months before prom. If it was supposed to suggest they are having spring practice, then he's not even supposed to be practising since he's a senior.
April: Uh, Jessica has a... problem.
Ling Ling: She's only going to make us wait an hour this time.
Lulu: What about the class trip to Six Flags. She took so long in the bathroom we missed the bus.
Ling Ling: Our parents had to drive three hours to pick us up.
Jessica (Clive): I had my period, OK.
