'''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: Parodied. Francis thinks Chris spends all his time in the bathroom masturbating, when he's really just... going to the bathroom.
* 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]]''.
* EarlyBirdCameo: Vern, the vaudeville performer who would appear often early in the revival. He does his routine without his piano-playing partner Johnny.
* 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. [[LampshadeHanging Don't know why they went with such a suggestive name when they could've just as easily gone with "rooster."]]
* NoodleIncident: "Lois, lunch is a sin. Taking a break is a sin. [[Main/BestialityIsDepraved Bestiality is a sin.]] [[Main/LampshadeHanging I don't know how that one came up, exactly."]]
* ObnoxiousInLaws: Francis to Lois.
* PottyEmergency: Chris spends the entire episode not going to the bathroom after Francis assumes he spends all his time in the bathroom masturbating and tells him what he does in there is a sin.
* [[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.
* TapOnTheHead: Parodied. When Peter steals the Popemobile, the guy guarding it tells Peter that "even the slightest tap on the head knocks me out. I always wake up feeling fine afterwards, but it's just so darned inconvenient." The fellow then demonstrates this by lightly touching his head and knocks himself out, allowing Peter to steal the car.
* 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 [[WhipItGood giving Peter the whip]].
* WaxingLyrical: Parodied after Francis walks out on a baseball game Peter invited him to.
--> '''Peter''': All I did was ask him to buy me some peanuts and crackerjack.
--> '''Brian''' (dryly): I don't care if he ever comes back. ({{Beat}}) [[NotMakingThisUpDisclaimer I wasn't being cute. I really hope he's dead]].
* 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]].
* {{Workaholic}}: Francis. The episode starts with him getting forced into retirement, and he later leaves a ball game Peter took him to and breaks into a factory ''just to keep working''. He's later shown to be hypercompetent enough to do Peter's entire day's work at the toy fact factory in seconds.
* WritingAroundTrademarks: In the "Superman in Hell" gag, not only is he not called by name, his cards [[SceneryCensor conveniently]] cover up his S-symbol.
