But in a newly discovered Mean Girls deleted scene, it's Janis' sidekick, Damien, who is doing the "evil stuff," rather than high school villain Regina George.
The clip, which takes place in the second half of the movie, sees Damien try to sabotage Regina by loosening the screws on one side of the cafeteria table.
He was hoping that Regina would place her food down, sit in the seat, and have her lunch pour all over her. But then dreamy Aaron Samuels arrives and distracts Regina with a kiss.
Cady was in on the prank and when she saw Karen sit in Regina's place, tried to warn her friend.
Watch the hilariously fetch scene below.
