Kappa Tau and Omega Chi face off in an epic battle of practical jokes complete with waterguns, duct tape and farm animals. Rusty tries to mediate the situation to save his friendship with Calvin but finds it only escalates the rivalry. Meanwhile, Casey learns that the only way to rid ZBZ of Lizzi, the conservative national rep overseeing them, is to forgive Frannie and reinstate her in a "diamond" ceremony.

When the ZBZ girls express their desire to reunite with the Omega Chi's, Casey is put in a position of having to face her past relationship with Evan head on, causing her to come to grips with her feelings about him. Meanwhile, Rusty has a new crush and oddly enough it is Dale who helps him get a date with the girl. However, since Rusty has only had one relationship in the past, his eagerness to find someone new just might backfire.
