'''Original air date''': September 30, 1999

Peter's Bible-thumping father, Francis, comes to visit, making Lois feel bad for being Protestant (since Francis is Catholic), Meg feel bad for having a crush on Joe's son, and Chris feel bad for pooping in the bathroom (which Francis mistakes for masturbating).
!!Tropes used in the episode:
* ADateWithRosiePalms: Francis thinks Chris masturbates a lot, Chris has been pooping.
* BadassGrandpa: Francis becomes a bodyguard for the Pope, even punching hard a FOX camera man.
* {{Bowdlerisation}}: On Channel 4's website in the UK, the title of the episode becomes "Holy Cr*p"
** When that same channel broadcasts the episode, they digitally erase the word "Whore" from the sign that Francis tacks on below the "Just Married" sign, so Francis' sign becomes "to a Protestant"
* CallingTheOldManOut: When Francis berates him at work, Peter stands up to him in a civil manner. [[DisproportionateRetribution His response is fire Peter]].
* ComicallyMissingThePoint: After hearing Francis' stories, Stewie becomes awed by God because he believes he's ''[[EvilCannotComprehendGood evil]]''.
* InnocentInnuendo:
--> '''Diane''': Tom, the city of Boston is examining its conscience tonight in preparation for a visit from the Pope.\\
'''Tom''': That's right, Diane. I'll tell you what else will be examined: This cock. (pulls up a rooster) The Rhode Island Cock Society is sponsoring free check-ups for this year's Cock Awareness Week.
* ObnoxiousInLaws: Francis to Lois.
* [[RacistGrandma Racist Grandpa]]: Not that Francis voiced anything against different races and ethnicities, but he has a low opinion of other religions and ways of life, like Peter's non-religious lifestyle and Lois's Protestantism.
* SentimentalMusicCue: Parodied; Peter has an orchestra on standby in case an emotional sitcom moment occurs.
* SlutShaming: At Lois and Peters' wedding, Francis tacked a sign reading "to a Protestant Whore" under the traditional "Just Married" sign.
** Years later, he tells Meg she'll go to hell for even holding Kevin Swanson's ''hand'' and tells Chris the same thing for supposedly masturbating.
* UngratefulBastard: Francis, full-stop. No matter what Peter tries to do to bond with him, Francis disregards him. When Peter manages to get him a job at the toy factory, Francis thanks ''God'' while giving Peter the whip.
* WeAreNotGoingThroughThatAgain: At the end of the episode, after Peter manages to get Francis a job with the Pope, his mother shows up needing a place to crash. The Griffins' response is to jump into [[Franchise/StarWars an Escape]] [[EscapePod Pod]] and [[ScrewThisImOuttaHere fly away]].
