Mordecai and Rigby explain why they need Benson's gumballs to prevent the universe from crumbling at the hooves of the Assault Space Station (or A.S.S.) and their legion of donkeys who attack anyone who happens to lose to a rap battle. They call BF for his services, but Benson doesn't initially understand him, so BF teaches Mordecai and Rigby how to rap, and Benson, finally realizing what's happening, decides to flex his rap skills. Benson decides that if they lose the rap battle, they're fired, but since they got trained by BF, they win, with a triumphant "Whoooooaaaaa" to celebrate. Now Benson has to give his balls to A.S.S. What a weird episode.
