In this week's main storyline, Hilary Duff led a trio of mean girls against Annie, Shirley and Britta. But the latter group soon learned that Abed can be crueler than anyone just by being observant.

They let him loose on the school, insulting everyone's appearances at every turn, and pretty much take over. They become the mean girls, but the power goes to their heads. Soon, Abed considers his friends to be "bitches" and cuts them down to size. But he isn't happy with this outcome and eventually gives insulting intel to Duff's character.

She responds by bashing Abed in front of the school and restoring the social order.

The B storyline involved Jeff and Troy finding a Secret Garden-like place next door to Greedale - with a trampoline! They were in heaven jumping away on it, as the man who kept it a secret, Joshua, explained that the trampoline brings one incredible serenity.

In the end, though, Pierce discovers the place and the toy and ruins it for everyone. Jeff and Troy even learn Joshua, who gets fired as a result of hiding a secret trampoline, was a racist. Hilarious stuff.
