Episode - 3F06\\
First Aired - 11/19/1995

After faking his own death and getting the mistake cleared up at the town courthouse, Homer makes a discovery: his mother, Mona (who supposedly died when Homer was a kid), is still alive, but the joyous reunion (at the cemetery after Homer discovers that the grave that allegedly belonged to his mom is, in fact, the grave of writer Walt Whitman) is cut short when the FBI comes after Mona for something she did in the 1960s, which is connected to Mr. Burns and is why she abandoned Abe and Homer.
!! Tropes:
* AndThereWasMuchRejoicing: Marge is further dumbfounded by the strange claims of Homer's "death" when Patty and Selma gleefully come over, having prepared his tombstone, with the inscription "We are richer for having lost him".
* ArtisticLicenseHistory: In the flashback to the night Mona attacked Mr. Burns's germ warfare lab, Abe is seen watching [[SuperBowl Super Bowl III]]. Howard Cosell - voiced by Harry Shearer, in this case - is shown on-screen, talking about the two quarterbacks in the game, the New York Jets' Joe Namath, and the Baltimore Colts' Johnny Unitas. Cosell is seen wearing a jacket with the ABC's Wide World of Sports logo on it (or, at least, a crudely drawn representation of one). In real life, Super Bowl III was televised by NBC, with Curt Gowdy calling the game. However, Cosell is more well-known these days than Gowdy, despite the fact that Cosell never called a Super Bowl in his whole career...and Gowdy called ''seven of the first 13''.
* AwLookTheyReallyDoLoveEachOther: When the FBI raided the house to arrest Mona, Abe immediately jumped up to distract them, though even he's not sure if it was a distraction or just senility.
-->'''Abe:''' A little from column A, a little from column B.
* BittersweetEnding: Homer had to watch his mom walk out of his life again after keeping her from getting caught by Mr. Burns. But this time, Homer was awake to see his mom leave.
* CoolOldLady: Bart likes Mona because she's a rebel and a fugitive; Lisa admires her strength and intellect.
* FakingTheDead: Homer did it to get out of picking up garbage at a highway during a Burns-sponsored event.
** Abe is revealed to have done this to Mona after she is forced into hiding, believing Homer would be better thinking she had died than willingly abandoned him.
* {{Foil}}: Mona to Abe. Abe is a senile, cranky, and unpleasant old man who goes off on wild tangents and generally annoys Homer and his family, albeit his wear and tear largely coming from all he has gone through with his family. Mona has aged with dignity, retained all of her faculties, and is someone Homer and his family loves to have around, though is left with a incredibly distant relationship due to her occupation.
* GrandmaWhatMassiveHotnessYouHave: Subverted. Mona has aged a lot better compared to Abe, not just physically but mentally.
* INeedToGoIronMyDog: While Lisa was spending time with Mona:
-->'''Mona:''' ''(sees something)'' Gotta go, grandma stuff!\\
''(She runs back inside, leaving Lisa confused. Then she saw a police car drive by.)''\\
'''Lisa:''' ''(concerned)'' Huh?
* JerkassHasAPoint: Abe was a pretty nasty father, but his anger toward Mona, for abandoning ''Homer'', is somewhat understandable. She just rolls her eyes; though he ''was'' a lousy husband as well.
* KnightTemplarParent: Homer first meets Mona after she obliviously roars at him as an "awful, ''AWFUL'' man" for ''accidentally'' tripping into her son's grave. This fierce side of Mona vanishes the moment he defiantly claims his grave and [[DelayedReaction the two figure it out]].
* LazyBum: Homer ''faked his death'' just to get out of trash duty.
* LoudOfWar: Mr. Burns plays an audio casette recording of ''Ride of the Valkyries'' as he storms the Simpsons' household...and the tape quickly cuts to {{Abba}}'s ''Waterloo'', which Smithers [[WeShouldGetAnotherTape admits]] he recorded over the original music.
* MoodWhiplash: The episode is full of this, with wacky scenes immediately followed by dramatic, emotional ones.
* NoCelebritiesWereHarmed: The FBI agents assigned to find Mona are [[Franchise/{{Dragnet}} Joe Friday and Bill Gannon]]. Harry Morgan reprised his role as Gannon.
* ObnoxiousInLaws: Marge's first reaction upon learning she had a mother-in-law was commenting she couldn't live vicariously through her friends who do have in-laws, though this is averted, as Mona is actually nice to Marge and the kids.
* PrematurelyMarkedGrave: After Homer is believed dead, Patty and Selma visit Marge to present her a gravestone with Homer's name on it for which (they say) they have been saving since Marge's wedding day. As Homer does not actually need it, they use it as a coffee table.
* PunctuatedForEmphasis: "I! Hate! You! [[Creator/WaltWhitman Walt]]! Freakin'! [[Creator/WaltWhitman Whitman]]! ''Literature/LeavesOfGrass'' my ass!"
* RhetoricalQuestionBlunder: Homer doesn't understand them. This example is even used at the top of the trope's page.
-->'''Mona Simpson''': (''singing'') [[Music/BobDylan How many roads must a man walk down / Before you can call him a man?]]\\
'''Homer''': Seven!\\
'''Lisa''': No, dad, it's a rhetorical question.\\
'''Homer''': Rhetorical, eh? ... Eight!\\
'''Lisa''': Dad, do you even know what "rhetorical" means?\\
'''Homer''': Do '''I''' know what "rhetorical" means?
* Music/RideOfTheValkyries: Mr. Burns plays it while assalting the Simpson home. However, Smithers had taped "Waterloo" by Music/{{ABBA}} over it (Originally, it was supposed to be WHAM!'s "Wake Me Up Before You Go-Go," but the producers couldn't get the rights to that song. It works either way, as both ABBA and WHAM! have a following with gay men and Smithers is speculated to be gay [whether with other men or just his boss]).
* TheSixties: Mona's rebelliousness is encouraged when she notices Joe Namath's long hair and the spirit of the 1960s falls upon her.
* WhatTheHellHero: When Abe meets Mona for the first time in years, they both call each other out for A: abandoning the family and B: telling Homer Mona was dead.
-->'''Mona''': Oh Abe, you've aged ''terribly''.
-->'''Abe''': Well what'd you expect?! You left me to raise the boy on my own!
-->'''Mona''': I ''had'' to leave! But you didn't have to tell Homer I was ''dead''!
-->'''Abe''': It was either that or tell him his mother was a wanted criminal! You were a rotten wife and I'll never, ever forgive you! ...Can we have sex, please?
-->'''Mona''' (''disgusted''): Oh ''Abe''...
-->'''Abe''': Well I tried. What's for dinner?
