During one of his visits Peter's father, Francis, discovers that Stewie has never been baptized, so without Lois' permission Peter and Francis go to church and have him baptized. Upon discovering this, Lois convinces Peter that Stewie should have been able to worship whomever he wanted regardless of his father's religion. Naturally Peter interprets Lois' wisdom the wrong way so decides to start his own religious group that praises the television character, Arthur 'Fonzie' Fonzarelli.
