Joy and Kat are assigned a class project together so they head over to Joy's house to work on it. Well, Joy thing Kat should work on it, after all, Joy is a little too busy going to parties to really worry about Florida politics. Kat, however, is more than eager to help if it means she gets to sit at the cool girls table. Who wouldn't want to sit there?
Kat goes upstairs to use the bathroom but also heads off into Joy's room to take a peak and use her bathroom instead. I guess Joy should have hidden her used diapers a little better because Kat found them laying around and took pictures. Who wouldn't? It's the best blackmail possible! The popular girl at school wears diapers! And she USES them too! On the way out she even finds a whole bag of them just laying on the dresser.
Back downstairs Kat then notices a little piece of a diaper sticking out the back of Joy's skirt and snaps a picture of it before confronting her by telling her how cute it is that Joy wears diapers. Joy denies it until Kat pulls up her skirt and reveals a wet diaper. Maybe our little popular girl needs a diaper change and Kat would be more than happy too. She's always been the baby and dorky and never got a chance to baby someone else. That is, until now. Plus, think of the power trip. The smart little nerd changing the popular girls wet diaper? If Joy thought that was bad, Kat wants to change her at school too. The band room has a private bathroom so no one would find out. Of course, Joy has no choice but to agree to having her diaper changed for her or else the whole school will find out!
