Peter's devout Catholic father, Francis, visits Quahog. Upon arrival, he insists that Stewie be baptized as a Catholic. After visiting a Church with Peter and Stewie, Francis is informed the holy water is tainted and he will have to wait. Francis is in disbelief, and baptizes Stewie himself. Stewie soon becomes unwell and is informed that he must be quarantined and kept in a germ-free environment by a doctor. Then Lois discovers Peter had Stewie baptized without her knowledge, and tells Peter to stand up for his beliefs and not allow himself to be bullied by his father. Peter converts to Mormonism, but discovers that Mormons cannot drink alcohol; he then tries Jehovah's Witnesses and attempts door-to-door conversion. He finds someone who is actually interested in hearing what he has to say; however, he fails to teach them anything about the religion. As a final attempt, Peter tries Hinduism; when he tackles the Hindu leader to the floor because he believes the red dot on his head is a laser spot from a sniper rifle, he is dismissed from the meeting. Unable to find a religion suited to him, Peter decides to create his own religion, based on Happy Days, calling his newly-founded Church The "First United Church of the Fonz".
