Factual error: The mall that the plastics state they are going to, Old Orchard as stated by Cady, is an outside mall. However, the mall they go to is an indoor mall.
Factual error: While the plastics are at the mall there is a Bell Mobility booth seen behind them. This booth wouldn't be found in an American mall as they only service Canada.
Continuity mistake: Cady breaks up her Spring Fling tiara that she receives. On stage, she breaks it up into many pieces and throws them out into the crowds; it is clear that the amount we see being thrown into the crowds is a major amount of pieces - almost too much from just one tiara. However then when she leaves the stage, we see her holding approximately half of the tiara still. This would not be possible from the aforementioned amount that Cady has already snapped off and thrown into the crowd. (01:25:15)
Trivia: Tim Meadows, who plays Mr. Duvall, broke his wrist a week before filming started and had to wear a cast. They explained this away in the movie by saying that Mr. Duvall had carpal tunnel syndrome.
Question: Why did the coach act so paranoid about safe sex if he was actually sleeping with a student?
Answer: He wanted to appear to be strict and "uptight" about sex, so people would be less likely to believe any rumors about him.
Answer: Precisely because he was sleeping with a student. Getting her pregnant would bring their affair out into the open and create a scandal for the whole nation to know what he was up to. Therefore safe sex was really important to him.

True, but since he was spending time with her, he could make sure that birth control was being used (i.e. him using a condom). I think he was trying to appear "uptight" about sex, so he could be the least likely suspect.
