Peter launches a crusade against illegal immigrants until he discovers that he actually ''is'' one thanks to his mom having him while in Mexico (following her affair with Peter's drunken, Irish dad).

!Examples:
* ArtisticLicenseLaw: The episode should be mostly a non-issue. Because Peter is the son of an American citizen (his mother), he is a naturalized citizen regardless of where he was born. The lack of a birth certificate could be a bit of a legal hassle, but he wouldn't be considered an illegal immigrant. Even if he was, Peter is old enough to have been around for the amnesty granted by the [[UsefulNotes/RonaldReagan Reagan administration]], so he should have had no problem applying for citizenship if it was still needed.
* BlackComedy: Peter's birth during the abortion is all PlayedForLaughs as he falls out of his mother during the attempted procedure, one man comes by and chops off his umbilical cord with garden shears and then another man blows it away (along with some leaves) with a leaf blower.
* FracturedFairyTale: One CutawayGag has Peter's cousin as one of the three little pigs, who talks the wolf out of blowing his house down because "[he] just made stool in there".
* GoodGirlsAvoidAbortion: Because she was impregnated by Mickey [=McFinnegan=], Thelma tried to abort Peter to prevent Francis from finding out that she's pregnant. However, her attempt failed as Peter came out of her during the attempted abortion.
* TheHelpHelpingThemselves: Discussed.
-->'''Peter:''' Lois, immigrants don't take handouts. They just take one DVD a month from the house they're cleaning until they have a respectable collection.
* IdiotBall: Angela, Peter’s boss, ends up concurring with him about his anti-immigration views, even though she saw first hand how incredibly nonsensical Peter can be.
* MoodWhiplash: When Peter finds out he was born in Mexico, the intense scene transitions to a more comedic scene where Peter, in a purple background, jokes about his predicament and sings a little tune.
* OriginalPositionFallacy: Peter is fired when he can't provide a birth certificate to demonstrate his citizenship of the USA. This comes about because of a policy against employing illegal immigrant workers which Peter himself encouraged the company to implement.
* PatrioticFervor: Peter spends the first part of the episode displaying an exaggerated version of this, until he discovers he was actually born in Mexico.
* PrisonRape: After Patrick Swayze gets arrested for dating an underage girl, he ends up in prison. While in prison in bed, he quickly turns around after seeing his room mate. After he does, the room mate starts to lick his ear.
* TomatoInTheMirror: Peter takes a grudge against illegal immigrants, only to be told he is one himself.
* VerySpecialEpisode: The episode tackles illegal documentation and immigration.
* YouAreWhatYouHate: Peter hates illegal immigrants for eating all the donuts and has them all fired and removed, so imagine his surprise when he turns out to be one too.
