At some point it sounded like Marilyn Manson.  I thought I was the only one crazy enough to hear some MM here.
You know, upon further examination I'd say this is among my favorite Beck songs. I can just relate to the lyrics and composition so much. Makes me think Beck is growing tired of Scientology but is in a tough spot being his family believes as well and how crazy Scientology can be about people leaving or speaking out against L. Ron Hubbard's work of fiction turned holy book.
