Plot (Spoiler)
Meg becomes a born-again Christian after watching a Christian TV show starring Kirk Cameron. She begins talking about Christianity to the Griffins, who are uninterested in her new-found faith. Meg asks Brian for help, but he confides that he is an atheist. She spreads the news of Brian’s atheism around Quahog (which detests atheists), making him a social outcast; he is banned from every bar and convenience store in Quahog, making it impossible for him to drink. Brian fakes repentance (convincing Meg to cease hostilities against him so he can return to drinking), but she takes him to burn bookswhich are “harmful to God”. Disgusted, Brian comes clean and tries to convince Meg that what she is doing is wrong. When she refuses to listen Brian points out that if there were truly a loving God, he would not have created Meg in a family contemptuous of her. Ashamed, Meg concedes and apologizes for her behavior. Brian then assures her that the answers are inside herself, and the real meaning of existence is out there. It is later revealed that the Family Guy universe takes place within the molecules of a lampshade in the bedroom of Adam West and Rob Lowe (who appear wishing each other good night in a live action scene parodying Bert and Ernie from Sesame Street).
