Break Up Not to Make Up

When Marcus and his girlfriend Dana break up, Mo steps in and goes out with Dana to a concert behind Marcus' back, creating tension between the two best friends. Marcus and Mo interrupt Floyd's date, asking for advice on the matter and the guys end up reconciling. Meanwhile, T.J. faces gym class and showering in the locker room for the first time -- and tries any way to avoid showering in gym class, because he is the "smallest" one in his gym class.
