Mean Girls (2004)

Nothing is more satisfying than seeing the ruthless Regina George (Rachel McAdams), leader of the Plastics in Mean Girls (2004), learn she was being tricked into eating weight-gaining nutrition bars. What's not so satisfying is the lengthy shrill scream she lets out, even scaring her boyfriend into running away. The screaming continues from the car to her home as she barges into her bedroom to indulge in the madness that is the Burn Book.
