Trivia: If you have the DVD for The Hot Chick, you can watch Deleted Scenes. If you see the one titled Carol's Phobias, you will see that Carol (Jessica's mother) has a phobia of germs. In the actual movie, when Billy comes to Jessica's house, Jessica walks on the roof and peers into her parents' room. While her dad is reading a playboy, her mom is reading a germ magazine.
Trivia: Michelle Branch is one of the DJs in the club.
Trivia: If you look at the deleted scenes from the movie one of the cut-out issues was that Jessica's mom was a germ-freak and always wearing a protective suit. In the scene where Jessica watches her mom pull away and goes up to the house pretending to be Taquito, you can see that her mom is wearing the suit in the car, although the whole matter was deleted from the final movie.
