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:
* CoolOldLady: Bart likes Mona because she's a rebel and a fugitive; Lisa admires her strength and intellect.
* DownerEnding: Homer had to watch his mom walk out of his life again after keeping her from getting caught by Mr. Burns.
* FakingTheDead: Homer did it to get out of picking up garbage at a highway during a Burns-sponsored event.
* GrandmaWhatMassiveHotnessYouHave: Subverted. Mona has aged a lot better compared to Abe.
* MiddleChildSyndrome:
--->''(Homer is in the Springfield Hall of Records, trying to clarify that he's not dead)''\\
'''Homer''': I don't like your attitude, you water-cooler dictator. What do you have in that secret government file anyway? I have a right to read it.\\
'''Bureaucrat''': ''(turns his monitor toward Homer)'' You sure do.\\
'''Homer''': ''(reads)'' "Wife: Marjorie. Children: Bartholomew, Lisa" -- aha! See, this thing is all screwed up! Who the heck is Margaret Simpson?\\
'''Bureaucrat''': Uh, your youngest daughter.\\
'''Homer''': ''(mocking him)'' "Uh, your youngest daughter."
* 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.
* PunctuatedForEmphasis: "I! Hate! You! [[WaltWhitman Walt]]! Freakin'! [[WaltWhitman Whitman]]! ''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]).
* 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?
