7x14 - Full House

Stephanie's classmate Jamie, who plays guitar with some friends in a band called "Human Pudding", asks Stephanie out on a date to the Smash Club, and Stephanie excitedly agrees to go to the Smash Club with Jamie. Stephanie's classmate Gia Mahan is not as excited, because Gia also has her eyes on Jamie, and she's not about to let Stephanie have him that easily. In order to make Jamie cancel his date with Stephanie, Gia spreads a false rumor at school that Stephanie wouldn't have any dates if she didn't pay guys to date her. Gia's plan works, and Jamie breaks the date, so Stephanie gets even with Gia by hanging up a blowup of Gia's awful report card in the hallway. This makes Gia feel even more hurt than Stephanie felt when Gia spread the false rumor about Stephanie. Noticing how hurt Gia feels makes Stephanie feel guilty.
