   Summary

   When the band grows tired of Lars' childish antics, they find an extreme way to set him straight. He's given a choice, either be the band's "baby" and put up with torment for a set amount of time, or be kicked out of Metallica for good.

   Will Lars learn to enjoy his new role as Metallica's little diaper brat?
