Acafellas

Will forms the Acafellas, an all-male a capella group, but spends more time building his own confidence than he spends with the Glee Club. With Will away, the club hires a choreographer to help coach them. Meanwhile, Mercedes falls for a boy at school, but he doesn't feel the same way back; and the Acafellas perform for the P.T.A. and get a visit backstage from Josh Groban.
