As the Bell Rings S01 E12 Presidential

Brooke runs for class president, and her success is determined by the vote of the boys. So each of the girls got caught up in the campaign election. They feel it is tacky to give away free stuff, but they decide to bake cupcakes. Tiffany is put in charge of hanging up the fliers and baking cupcakes but instead puts the flyers in the cupcakes making them a success.
