You're Not My Father

"Margo: Just so you know: you're never gonna be my dad. Gru: Hmm. I think I can live with that."

- Despicable Me

The closing line to any fight or disagreement between a teenager and either his father/mother or (more commonly) his important replacement parental figure (in the right genre, between the hero and his mentor). This is either a loophole for someone who really is in the wrong and wants a reason to end the argument without defending himself, or a way for a Good-aligned (or standards-bearing) offspring to inform his Evil-aligned father [figure] that he has crossed the line and is no longer worthy of respect, admiration, or obedience.

A stipulation is that the mentor has been more of a parent than the referenced father ever was. Or maybe an older brother with a Promotion to Parent.

A twist that turns up the tension is "You're not his father."

Compare/contrast with I Have No Son.

Anime
"Nanoha: Vivio, this might hurt a little bit..."
 * Used by Vivio on her adoptive mother Nanoha after in Magical Girl Lyrical Nanoha StrikerS. This happened while Nanoha was being fueled by Mama Bear rage. Ouch.


 * In an unusual variation, Vivio meant this literally.
 * Shinji Ikari of Neon Genesis Evangelion is practically a trope-namer, he uses it so much.
 * Ace uses this phrase on Garp in a flashback in One Piece, in response to him opposing his plan to become a pirate. Unlike some who invoke it on a non-biological father figure, he doesn't think much of his biological father.
 * Kyo from Fruits Basket shouted this (in a flashback) about his adoptive father, who became distant after overhearing it. It turns out it was because.

Comics
"Liesl: How is that any of your business? You're not my dad. I do what I have to do. I was told to hide, I hid. I get scared, I deal with getting scared my own fucking way. Clear? [Beat Panel] Liesl: You're not my dad, right? Spider: No. Liesl: Good. [Beat Panel]"
 * Spider Jerusalem from Transmetropolitan was once told this by a person he was trying to interview.

Film
"Denny: You're not my fucking mother!"
 * The Room.

"Uncle Ben: Now I don't mean to lecture you, and I know I'm not your father... Peter: Then stop pretending to be!"
 * The last conversation Peter and his uncle Ben share in the Spider-Man movie:

"Peter: I had a father... his name was Ben Parker."
 * Echoed in a later line:

"Sonny: That's easy for you to say; he's not your father. Tom: I was as much a son to him as you or Mike."
 * "You ain't my pa."
 * Inverted in The Godfather:

"Todd: John, do as your mother tells you. John: She's not my mother, Todd."
 * Embraced in Part II, when Connie tells Mike, "You're not my father!"
 * Said by Kristy in the Babysitters Club movie, when her stepfather berates her for coming home late—from a secret visit with her biological Disappeared Dad, but he didn't know that. Made all the more heart-breaking by the fact that there are several points in the books where Watson plainly calls Kristy his daughter, even giving her an antique family heirloom in the Little Sister Spin-Off, and her biological dad stood her up in the end, anyway.
 * A little jarring though; this is never resolved in the movie (with Kristy apologizing to Watson for what she said), outside of her narration explaining to the audience she felt bad.
 * A variation occurs in Terminator 2 with John Connor.

"Joe: You know what my kids would say... Tom Servo: "You're not my real father!""
 * Played in Indiana Jones and the Kingdom of the Crystal Skull as a brief point of contention for Indy and Mutt, as they'd only recently met. Having been raised to believe his father was a British war hero, Mutt doesn't accept the news at first.
 * Said by Jerri in the Strangers with Candy movie to Stew the meat-man, who promptly responds, "You're not my daughter!"
 * Inverted in Star Trek where Spock meets future Spock, who says "I'm not our father."
 * At the end of Ninja Assassin, Raizo confronts his old mentor Lord Ozunu, who wants Raizo to "beg [his] father for forgiveness". Raizo shoots back "you are not my father", prompting a shadow-blending ass-kicking from Ozunu.
 * For reference, Ozunu had Raizo and dozens of others kidnapped as children and put through Training from Hell to become ninjas. As far as Ozunu was concerned, they were all his children.
 * A gag in Mystery Science Theater 3000: The Movie:


 * In the second live-action film of George of the Jungle, Junior says this to Lyle Van De Groot after  Twice. And kicking him in the shins both times.

Literature

 * Elaine Isaak's Eunuch's Heir—used by Wolfram, the title character, against his (unbeknownst to him) actual, biological father.
 * Both used straight and inverted in Lamb the Gospel According To Biff. Joshua (Jesus) uses the line straight when arguing with Joseph; then Joseph, at a later point, points out "I'm not your father".
 * In Harry Potter and The Order of The Phoenix, Sirius tells Molly that Harry is "not her son." Her response? "He's as good as."
 * To make this variant more interesting, Harry feels touched by this... but then goes against Mrs. Weasley's wishes anyway.
 * Anna uses this on Isabel in Stepmom, and Isabel's response is "THANK GOD FOR THAT!"

Live Action TV
"Will: I've been waiting for this for a long time, my whole life, and nobody's gonna stop me now. Come tomorrow, I'm outta here. Uncle Phil: Oh, I don't think so. Will: Who cares what you think? You're not my father!"
 * The lines are spoken word-for-word on Heroes on several occasions when Claire Bennett tries to assert her independence from Noah, aka HRG guy. Naturally, her not-dad, despite his communication shortcomings, is usually right.
 * To be fair, dealing with her real father and grandmother soon prompted her to declare "I have a family!" and jump out a tenth story window to escape from them.
 * The Fresh Prince of Bel-Air, in the landmark episode when Will's loser father shows up and invites his son to take a road trip. Will jumps at the opportunity, despite his uncle's warnings that his father can't be trusted.
 * The Fresh Prince of Bel-Air, in the landmark episode when Will's loser father shows up and invites his son to take a road trip. Will jumps at the opportunity, despite his uncle's warnings that his father can't be trusted.

"Tamera: I don't need a DNA test to know who my real father is. He's the man who's been there for me my entire life. And a good part of yours too Tia. His name is Ray Campbell. And as far as I'm concerned, he is all the father I will ever need."
 * Sister, Sister: When Ray tells Tia that her new boyfriend just got out of prison and the bottom line is that she can't go out with him, she responds, "Well, bottom line, you're not my father!"
 * Tamera says the reverse near the end of the series when Tia and Tamera meet someone who could very well be their biological father. Tamera gets pissed when he asks them to take a DNA test to confirm that he is their real father:

"Ed: You're not his father. Eric: Neither are you."
 * 7th Heaven, in the episode when Eric is trying to protect Robbie from his recently resurfaced deadbeat father, Ed:

"Charlie: Who the hell are you, John? Aaron's not your responsibility. ...You're not his father. You're not his family. Locke: Neither are you, Charlie."
 * Perhaps not quite average for the trope since the boy in question is a baby, not a teenager... But the line came up, unavoidably, in a very tense scene in the Lost episode "Fire & Water". Charlie, insistent on baptizing Claire's baby son regardless of Claire's wishes, runs afoul of Locke:

"Zoe Slater: You can't tell me what to do, you ain't my mother! Kat Slater: (Zoe's "sister") Yes I am!"
 * A really bizarre example occurs in the UK science fiction comedy Hyperdrive. Technical Officer Jeffers is reminiscing about being raised by a computer simulation of his father, created when his father knew he was dying. Then, when Jeffers was fifteen, they got into an argument, and Jeffers said "You're not my real dad! You're just a piece of code!" and deleted the program. He tried to restore it the next day, but couldn't.
 * The British Soap Eastenders had this sort of conversation, subverted because:

"Just because he's dead doesn't make you my father."
 * Six Feet Under - Claire uses this line plenty on older brother Nate.
 * In Nip Tuck, Matt says this to Christian right after the latter bails him out of jail..
 * A slightly depressing example occurs in the last episode of Supernatural, Season One. Sam and Dean have managed to rescue their father and Dean is worrying about having wasted a bullet (it only has a few left and they need all the bullets they can get). Unknown to them, John has been possessed by the Big Bad ever since they found him. But when John comes out and tells Dean how proud of him he is, Dean realizes the truth and says exactly this.
 * Played straight in a Season Five episode; a depressed Dean tells this to Bobby.
 * There's an episode of CSI: Miami in which Horatio meets a teenage boy. Horatio keeps calling him 'son', until the boy snaps back at him 'You're Not My Father'... little does he know that Horatio had earlier run a paternity test...
 * Angel: Angel's son Connor, raised by Angel's sworn enemy in a hell dimension, gets off at least one of these Eastwood style. He later identifies Angelus as his real father (who he wants to kill).
 * On Mystery Science Theater 3000: Pod People, after singing "Clown in the Sky", Joel tells the bots that he loves them. Crow's reply is "You're not my real father!"
 * In a House episode, the titular character reveals that he figured out that his father (John House) was not really his biological father when he was twelve, and told this to him, causing John to not speak a single word to his son for two months.
 * Freddie on iCarly uses this when Lewbert, their building's doorman enters a relationship with Freddie's mother.
 * Used in Fringe after.
 * Delivered in a stunningly awesome way from in Smallville, just before the former cuts ties with the latter completely.
 * Andrea in The Walking Dead, when arguing with surrogate father figure Dale: "I'm not your little girl, I'm not your wife, and I'm sure as hell not your problem."
 * Morgana does this indirectly on Merlin, telling someone that she comes in the name of Gorlois because Gorlois made her who she was, not her real father, Uther.
 * On Charmed, Paige delivered this line to her adopted parents during an argument on the day before they died, and spent years feeling guilty about it.
 * On Revenge: rebellious teenager Declan to his older brother Jack when Jack is trying to convince Declan he has a duty to attend their father's funeral:


 * Subverted on Who's The Boss? when Angela and Samantha get into an argument and Angela orders Samantha to go to her room. Samantha immediately shoots back that Angela isn't her mother. Tony intervenes, pointing out that he's her father, and he orders her to listen to Angela.

Stand-Up Comedy

 * In a routine done by Robin Williams, the Biblical Joseph, after hearing Mary is pregnant and he'd be "the stepfather of God's kid," fears he won't be able to discipline Jesus since he'd just scream, "You're not my real dad!"

Video Games

 * In Super Paper Mario,
 * In The House of the Dead III, Daniel says this verbatim as he delivers a final shot to the Final Boss of the game. See the page quote for more details.
 * Late in Disgaea, Jennifer chews out her foster father, who only adopted her to use her for his plans. In the anime, she actually says "you're no father to me!"

Web Comics

 * "Would you quit calling him that?!! He's not your daddy! Neither of us has a daddy!" "Don't say that!" Slap!
 * Gunnerkrigg Court. Renard tries to lecture Annie about stealing homework answers from her friend Kat. Annie tries to brush Renard off by pointing out that he's not her father. Renard replies that he would have been a better father than her real dad was, and things just go downhill from there.
 * In No Rest for The Wicked, November says this to the witch—who is seriously delusionally and believes her to be Gretel.
 * Said by Jeshua in Shortpacked, to Galasso, the nutjob who brought him back to life to be an attention grabbing gimick for his toystore. Given who the real dad is, its significantly more of a threat than usual.

Western Animation
"Zuko: After I leave here today, I’m going to free Uncle Iroh from his prison and I’m going to beg for his forgiveness. He is the one who has been a real father to me. Ozai: That’s just beautiful. Maybe he can pass down to you the ways of tea and failure."
 * Ben 10: Ben tells Grandpa Max, "You're not my dad!" when Grandpa scolds him for using the Omnitrix to sneak somewhere and play a video game.
 * While Calling the Old Man Out, Zuko of Avatar: The Last Airbender tells Firelord Ozai this.

"Goofy: Hold it right there! Max: [sees Goofy and is stunned with anger] Dad? YOU AGAIN?! Goofy: [happily] Maxie! Thank goodness, I came back to see you! Max: [becomes enraged] I THOUGHT I TOLD YOU TO-- Goofy: [interrupting him] Now listen, son. [angrily] My own life's OFF!! Max: [gasps in shock] Y-Y-You're own life's off?!?! Goofy: Of course! Max: Hold on! I'm a grown up, because you are my WORST nightmare! Goofy: Nope. You are my son! Max: I'm not you're son! Goofy: [angrily] YOU ARE MY SON!!!!! Max: [goes berserk] YOU'RE STILL NOT LEAVING ME ALONE ABOUT IT??? [he screams ferally and two of them start fighting]"
 * And then there's Zuko's beautiful Calling the Old Man Out speech, which heavily overlaps with Kirk Summation and "The Reason You Suck" Speech. See those pages for more details.
 * An Extremely Goofy Movie:

"Slade: I may even become like a father to you. Robin: I already have a father. (cue pan up to bats flying overhead)"
 * Batman declares this once in the animated series. Being Batman (and, y'know, knowing that his parents died years ago), he's right. The hallucination of his father that's been haunting him ever since Scarecrow gassed him disappears and doesn't return.
 * In Teen Titans, Slade manages to Blackmail Robin into being his apprentice:

"Bush: Jenna, get over here right now! I am your father! Jenna: That's not true! That's impossible! My real father would let me go clubbing as late as I want! *flips off Bush*"

 * Robot Chicken has their skit "Jedi Master George W./Jedi In Chief" more or less parodies this trope during a parody of the I Am Your Father scene in Star Wars, with George Bush as Vader and his daugher Jenna replacing Luke:
 * Robot Chicken has their skit "Jedi Master George W./Jedi In Chief" more or less parodies this trope during a parody of the I Am Your Father scene in Star Wars, with George Bush as Vader and his daugher Jenna replacing Luke:

Real Life

 * A serial killer was apparently able to kill about six women operating by this trope. Said women were drug addicts, prostitutes, women that their families just didn't care about anymore.
