->''"I'll be a better single parent than all of my high school girlfriends combined!"''

[[TheTalk In order to create a baby, a man and a woman need to have sex]]. [[note]] Barring, of course, artificial insemination, [[CloningBlues cloning]], or the odd MysticalPregnancy. [[/note]] Strictly speaking for the man this is an act of minimal investment since he can (and sometimes does) ditch the woman and leave her holding the bag (or baby, if you will). Unless she gets an abortion ([[GoodGirlsAvoidAbortion which she only very rarely does]]) or puts the baby up for adoption, she either has to raise the child alone or with the help of a stepfather.

This trope is what happens when the sperm donor, having been absent for most of the child's life, is revealed to be the father and all of a sudden everything is chillin' between him and his long ago Love Child.

It can be justified if DaddyHadAGoodReasonForAbandoningYou. Still, this trope is a bit of a harder pill to swallow when the guy in question suddenly receives a PromotionToParent in spite of not actually having done a whole heck of a lot to deserve it. This trope is commonly averted if the stepfather is a sympathetic character in the story. On the flip side, if there is a stepfather and we hardly even see him, chances are that sperm daddy is going to be the one referred to lovingly at the end of the story.

SubTrope of ChosenConceptionPartner.

[[folder: Anime and Manga]]
* Deconstructed in ''Manga/SakendeYaruze''. When they initially meet for the first time Shino is reluctant but quickly decides to take Nakaya in and they get along well despite the fact Shino wasn't there for the first 17 years of Nakaya's life. However, their relationship proceeds to go through a series of ups and downs, Shino trying to act like a father when Nakaya doesn't want him to or not acting like a father when he does want him to, while Nakaya at times idolizes Shino and then at others pushes him away. In the end Nakaya decides to move out because he feels uncomfortable with his father's new relationship but doesn't want to ask Shino to give it up because their father-son bond is too new for him to feel right in doing so.
* ''Manga/HunterXHunter'' has a far more nuanced version of this. Gon looks up to his father, Ging, as a great Hunter, and wants to find him and learn more about him, but seems well aware that Ging, who walked out on him when he was a toddler, is not going to be a candidate for Father of the Year. He also explains his general disinterest in his biological ''mother'' by noting that his Aunt Mito, who raised him, is already filling that role.

[[folder: Comic Books]]
* In ''ComicBook/{{Watchmen}}'', [[spoiler:the Comedian, who is referred to positively by the end of the book by both the first Silk Spectre (the mother) and the second Silk Spectre (the daughter) though she spends most of the time after she learns her true parentage conflicted about his (lack of) role in her life and the circumstances that led to her conception, since he had first attempted to rape her mother but later began a consensual affair with her after he reconnected with her and she believed that he had changed, but he's still viewed as a douchebag by most of the cast and an AssholeVictim at worst.]] This is greatly due to the GreyAndGrayMorality that ''Watchmen'' enjoys.

[[folder: Fanfiction]]
* This trope is often played up to insanity in fanfiction. In particular, [[TheSmartGuy Hermione Granger]] of Literature/HarryPotter, paragon of muggle-born and [[FriendToAllLivingThings champion of the rights of the underdog]], will immediately [[FaceHeelTurn switch sides]] and become a [[KickTheDog House Elf kicking]] bigot the moment she finds out that [[FanNickname Daddymort]] [[LukeIAmYourFather is her father]].
** {{Fanon}} has been known to like playing with the idea that "muggle-born" witches and wizards are actually the illegitimate children of Pure- or Half-Blooded wizards (always dark, usually Death Eaters) who take advantage of [[PowerPerversionPotential love potions or the Imperius Curse]] to have their way with muggle women. It doesn't help that Merope Gaunt actually did this with [[spoiler:Tom Riddle Sr., giving us babymort]], or that [[spoiler:Dean Thomas's father was a (very heroic) variant of the trope, being a pureblood who was killed by Death Eaters after abandoning his family to keep them safe]].
* One of the [[EpilepticTrees numerous]] explanations of [[{{Anime/Pokemon}} Ash Ketchum]]'s DisappearedDad is this trope.
* ''Roleplay/DCNation'': Lian Harper refers to Cheshire as a "glorified egg donor." Her stepmother (Donna Troy-Harper) is "Mom in all the ways that count!" Cheshire is less than happy to learn this.
* In ''FanFic/TheNewRetcons'', Wilf starts regarding both [[ComicStrip/ForBetterOrForWorse John and Elly Patterson]] as this, once Elly loses her mind and claims that her youngest daughter April isn't her daughter at all and throws her out, and John doesn't try to seek treatment for Elly and gives up on convincing Elly that April's her daughter. April's own feelings on the matter are...complicated.
** [[spoiler: For years Stan Watson believed his son Michael regarded him as this, since that was what Elly told him. He's angry when he finds out that she never told Michael that Stan was his biological father, letting him believe John was his father the whole time.]]
* It's very popular in the ''WesternAnimation/PhineasAndFerb'' fandom to have [[DisappearedDad Phineas and Candace's absent bio dad]] and [[MissingMom Ferb's missing bio mom]] be their respective gender's version of this trope. A particularly strong example appears in [[https://www.fanfiction.net/s/7738981/1/Capturing_the_Past ''Capturing the Past'']] with Stacy out and out stating this trope albeit not by name.
* ''Series/BuffyTheVampireSlayer'' fanfiction ''[[http://dark-solace.org/elysian/viewstory.php?sid=4134 The Light of the World]]'' plays with this, in that it's revealed that Dawn, Buffy's magically created sister, was created from Buffy (making her the "mother") and Spike (making him the "father"). Spike slipping easily into the life makes sense because A) Dawn currently doesn't know he's her actual father, and B) even though she appears to be fourteen (and remembers fourteen years of her life) she [[YoungerThanTheyLook really isn't that old at all]].
* What [[spoiler:John Constantine]] is in [[spoiler:Wanda Maximoff]]'s eyes in ''FanFic/ChildOfTheStorm''.

[[folder: Film]]
* A Glorified Egg Donor GenderFlip of this trope in ''Film/TheChamp'', wherein Andy's ex-wife swoops in and wants to take their son Dink away, years after she divorced Andy and left them both for a rich new husband.
* Another Glorified Egg Donor in ''Film/TokyoTwilight'', in which mother Kisako tries to reinsert herself in her daughters' lives after abandoning them 20-odd years ago when they were small children. Younger daughter Akiko doesn't even remember her; older daughter Takako tells her mother to bug off.
* In ''Film/MoscowDoesNotBelieveInTears'', Katya's lover Rudolf dumps her when he finds out she's pregnant. Twenty years later he runs into her again and insists on meeting his daughter, much to Katya's displeasure.
* In ''Film/SupermanReturns'', Superman fills this role. He ditched Lois for five years without giving an explanation to anyone. He seems to have had no idea (until the end of the movie) that he had even gotten her pregnant.
* Used in ''Film/MammaMia'' with a generous dose of LampshadeHanging. No one else on the island thinks the heroine's desire to find her GlorifiedSpermDonor makes a whole lot of sense, and she even realizes this herself at the end of the movie.
** All three dads decide they're willing to be her dad at the end, too. One-third of a kid isn't bad...
* {{Deconstructed}} in ''Film/TheKidsAreAllRight'', which takes a serious look at the ethical ramifications of this trope. Paul's apparent status as an instant parent comes off as insulting to Nic, as she and Jules were the ones who actually raised the kids. At the same time, the kids' desire to know their bio-daddy is shown as nuanced and reasonable--he is, after all, the only biological connection between them.
* ''Film/TheBigLebowski'': Maude Lebowski takes the "glorified" out of this when she has the Dude become the father of her child. She doesn't want to have to see the father socially, nor does she want the father to be invested in the raising of the kid. The Dude, of course, is cool with this.
* Exaggerated in ''Film/{{Starbuck}}'', a Quebec film. The protagonist, David Wozniak, sold a great amount of sperm to the sperm bank, fathering over 500 people under a pseudonym. Once most of them grew up, they tried to nullify his anonymity through legal means. David sued the sperm bank to prevent this from happening, and won the case. No long after, he decides to reveal his identity publicly. All his children began to love him dearly.
** This story is remade as the American film ''Film/DeliveryMan'' featuring Vince Vaughn as the protagonist sperm donor.
* In ''Film/AStoryOfFloatingWeeds'', Kihachi, the leader of an itinerant theater troupe, has never even told Shinkichi that he is his father, and he's been away for years at a time to boot. This does not stop him from getting all self-righteous and trying to act like a protective dad when one of the actresses in his troupe seduces Shinkichi.

[[folder: Literature]]
* In ''Literature/ABrothersPrice'' it is considered completely normal to have a sperm donor as father, as men are very rare. Women of the lower classes usually go to so-called "cribs" to get pregnant, and the sperm donor is documented to avoid inbreeding. Only from middle class up do people have an actual ''father''. The Whistler family has a shared grandfather and shared father, and may not be otherwise related at all - Jerin suspects that his grandmothers just pretended to be sisters, in [[ItMakesSenseInContext order to be able to rise to middle class.]]
* Martin Silenus' father in the ''Literature/HyperionCantos'' is this trope UpToEleven: Not only was he completely uninvolved in Martin's upbringing, he was completely uninvolved in his ''conception'', as well; ''long after he died'', his wife decided to hop onto a machine "part squirt gun and part dildo" to squirt his preserved seed into her "at the magic touch of a trigger" when "the moon was full and the egg was ripe." Yeah.
* Used twice in John Varley's ''Literature/SteelBeach'' when Hildy refuses to inform her baby's father that she's pregnant even though her own mother's constant refusal to identify ''her'' father causes her considerable angst. [[spoiler: After the baby dies her reasoning shifts from a selfish "mine, all mine" to "why ruin his [the father's] day?"]]
* In the ''Franchise/StarWarsExpandedUniverse'', this is a ''grave'' insult among Mandalorians. As in "make out your will beforehand" insult. A Mandalorian father who does ''not'' stick around to raise and train his kids is violating one of the six actions central to their society and therefore considered a ''traitor.''
* In ''Literature/PercyJacksonAndTheOlympians'', some of the kids at camp get this; many of the kids in the Hermes Cabin are not Hermes's children but unclaimed by their actual divine parent, or who have a divine parent who does not have a cabin at camp, and this does lead to bitterness and resentment among some campers.
** [[spoiler: In The Last Olympian, Percy puts a stop to this policy, requiring the gods to acknowledge their children at age 12, and that all the gods have their own cabin for their children. The gods aren't all that pleased about it, but Percy did just save all their hides, and that resentment fueled a great deal of the conflict, so they agree.]]
* In Creator/CarlSagan's ''Literature/{{Contact}}'', [[spoiler: the man Ellie thought of as her curmudgeonly stepfather turns out to be her biological father, and her late, loving "dad" was merely the man who raised her. When Ellie learns this, she immediately starts referring to her biological father as "her father", a practice which most RealLife people who were adopted as children don't actually engage in.]]
* In ''Literature/TheGoblinEmperor'', Maia's father, the elven emperor, immediately banished his mother, Chenelo, to a country estate when she got pregnant, for no better reason than that the marriage had been arranged and he had really loved his recently deceased wife. Of course, Chenelo being a goblin didn't help any. The only time Maia ever met his father was at Chenelo's funeral, eight years later. When the emperor and his three eldest sons die in an accident, Maia succeeds to the throne, and has to pretend that he is sad about his father's death, wearing full court mourning and all.

[[folder: Live Action TV]]
* Hotdog in ''Series/{{Battlestar Galactica|2003}}'', after he's {{retcon}}ned as Nicky's father.
* ''Series/TheFreshPrinceOfBelAir'' devotes a full episode to that. Will's birth-dad Lou comes and Will's excited about taking a trip with him, only to be abandoned again. The episode ends with Will sobbing in Uncle Phil's arms and realizing he's the closest to a real father he could ever ask for.
* ''Series/{{ER}}'' does it with Sam's son Alex. Just as Luka (Sam's boyfriend) has become a suitable role model and father figure, his felon birth-father Steve appears for the first of several times, causing a lot of conflict. The long plot has its ups and downs including Alex visiting his dad in prison and ending dramatically with Steve abducting Alex and Sam, raping the latter and being shot by her.
* ''Series/GameOfThrones'':
** Noblemen are ''expected'' to be this to their bastard children, who are commonly just left with their mothers or fostered by another family. That Ned and Oberyn avert this is considered remarkable to the court in King's landing, although it's perfectly normal in the North and Dorne (respectively). It even brings down the ire of Ned's wife, who is not from the North.
** Jaime sired all of Cersei's children, but wasn't a father figure to them from fear that people might get suspicious about their paternity. As of Season 5, he begins to regret this. Cersei tells him he has no right to call Myrcella his daughter, and Myrcella herself says he doesn't really know her.
* ''Series/GilmoreGirls'':
** In one car, Luke's nephew Jess comes to live with him. Jess has never known his father. The string of stepfathers he's lived through are implied to be pretty unreliable. Luke is the closest, most stable thing to a father he knows. But when his Bio Daddy comes to town--doesn't even say anything, mind you, just rocks out to a Bowie song with him--Jess drops Luke, his girlfriend, and everything he's come to care for just to spend some time with Daddy out in California. It was an [[PoorlyDisguisedPilot aborted attempt at a spin-off]].
** Arguably Rory's father Christopher qualifies. Lorelai realized early on that Christopher was too immature to be a husband and father, refusing to [[ShotgunWedding marry him]], much to their parents' chagrin. While Christopher may have wanted the family with Lorelai and Rory, he was never more than an intermittent presence in their lives until Rory was in her late teens. [[spoiler:In the revival, when Rory finally asks him why he was never there and why he didn't change Lorelai's mind in raising her alone, he fully admits to being young and stupid. He also tells Rory that after he saw how Lorelai first held baby Rory, he knew that there was nothing he could do to convince Lorelai otherwise and just let her.]]
** One episode addressed this. Christopher accuses Lorelai of turning Rory against him and not letting her be with him more. Rory steps in and calls him out about how this and the above were not her mother's fault, but his, and that she avoided him because she wanted to.
** Also addressed when Christopher attends a Yale event and Rory's schoolmates' parents are talking about how they had to be there for their kids all of their lives, helping out with assignments, coaching the soccer team, etc. Christopher felt bad and tried to overcompensate it with not very good results. It's not certain whether he ever fulfilled the role in more ways than being an "executive parent" (paying tuition, attending college graduation). Luke, on the other hand, was indeed ''always there for her.''
** Luke himself later finds out that he had a daughter he was never told about by an ex-girlfriend. He freaks out when he realizes that he's basically been this to her for the last 13 years. In fact, his relationship with Rory (specifically, Lorelai's character reference for him as a caring, reliable father figure) is part of what helps him earn shared custody when things get nasty between him and the mother (because she wants to move away and sees no problem with cutting him off from the daughter she never gave him a chance to know).
* When Nathan Petrelli on ''{{Series/Heroes}}'' finds out that the daughter he thought had died as an infant is alive and well it leads to this exchange with his mother:
-->'''Nathan''': I'm this girl's father, Ma!
-->'''Angela''': You're a [[TropeNamers glorified sperm donor]]. Don't get emotionally attached.
* Averted on ''Series/{{Friends}}'', where Phoebe's dad eventually comes back eighteen years after abandoning her and her mother, only to find Phoebe quite pissed at him. Eventually she warms up to him, but it doesn't come even close to "glorified".
* Subverted in ''Series/{{Glee}}'', though in this case it's an egg donor. Rachel eventually does learn that Shelby Corcoran is her biological mother, but she can't see her as a mother figure, and Shelby simply isn't fit to be a parent. Rachel keeps living with her [[HasTwoMommies dads]], and doesn't see Shelby again.
** Quinn treats Puck as this for most of the first season, deciding that Finn (who thinks the child is his) will be her baby's real dad (that is until the truth comes out and he dumps her for cheating, lying, and manipulating him).
* Inverted on ''Series/{{Community}}''. Jeff finally finds his father in season four, and William puts himself on the pedestal by attributing Jeff's self-reliance and independence to him leaving. Jeff tells him to go to hell.
* On ''Series/LawAndOrderSpecialVictimsUnit'', Amaro had an affair with his target's sister while on an undercover assignment, and ten years later discovers this resulted in a child. They were [[StarCrossedLovers forced apart by the end of Amaro's assignment]] and weren't able to find each other afterward, meaning she never got a chance to tell him she was pregnant, and had to raise the child alone. Amaro immediately tries to establish a relationship with his son, and is extremely pained that he missed so much of the boy's life.
* ''Series/{{Bones}}'': In "The Salt In the Wounds", Booth and Brennan uncover a murder connected with a group of teen-age girls who formed a "pregnancy pact"; the girls agreed to get pregnant and raise their respective children together without the aid of the fathers. Brennan found this an acceptable solution. Booth, not so much.
** Booth and Brennan themselves averted this trope in "The Cricket in the Cabernet", when Brennan, in the middle of a WordAssociationTest, suddenly announced, [[MyBiologicalClockIsTicking "I want a baby"]]. She decided she wanted a child through artificial insemination and wanted Booth to be the donor, but Booth was initially reluctant, especially when Brennan indicated that his involvement in her child's life would end at conception. The plot was more or less abandoned after Booth suddenly had to have surgery to remove a brain tumor (seeing [[WesternAnimation/FamilyGuy Stewie]] everywhere was an indicator that something was not quite right). Two seasons, as many [[RomanticFalseLead Romantic False Leads]] and several TearJerker moments later, [[TheyDo they conceived a child the old-fashioned way]].

[[folder: Mythology]]
* Some portrayals of the [[Characters/ClassicalMythology Hercules]] myth show Zeus as being distinctly hands-off, allowing other Gods to harass Hercules at will. Admittedly, Zeus' parenthood here is glorified for good reason, since his parentage is what makes Hercules a Greek SuperHero. In fact, more often than not in Greek Mythology, the spawn of the gods get some kind of nifty powers which at least make the being dumped off by your parents pill a little easier to swallow. Zeus and ancient patriarch and/or warrior gods in general have a habit of leaving little bundles of Demi-joy all over the mortal landscape and then doing bupkis about them. And while other Greek gods didn't see their children picked on as much as Zeus', their children typically didn't see much of the divine parent, either. Which might've done them a favor, since Hera often [[WomanScorned actively hounded]] the (often unwilling!) mothers and children, with other gods sometimes having to step in to try and save them.
** Also, as it turns out, ''not'' getting the attention of Zeus is far better than the alternative. When Zeus finally took a good look at the mortal world, he decided there were far too many demigods running around, and ''[[{{KillEmAll}} orchestrated the Trojan War to thin their numbers out almost to nonexistence.]]''

[[folder: Music]]
* Recalled in very realistic and bitter fashion in ''Music/DeathCabForCutie'''s "Styrofoam Plates". Mind you, he's saying this [[NeverSpeakIllOfTheDead at said sperm donor's funeral]].
-->It's no stretch to say that you were not quite a father
-->But a donor of seeds to a poor single mother
-->That would raise us alone
-->We never saw the money
-->That went down your throat through the hole in your belly
* ''Music/{{Everclear}}'''s song "Father of Mine".
* "Papa's Song" by ''Music/TupacShakur''.
* ''Music/TheGaslightAnthem'''s "Keepsake", though the lyrics make it clear that he doesn't expect an instant relationship or much of anything.
-->And I'm not looking for your love, I'm only sniffing out blood
-->Just a little taste of where I came from
* ''Music/{{Heart}}'''s "All I Wanna Do Is Make Love to You" is about a woman whose partner is unable to impregnate her, so she picks up a hitchhiker to perform the honor.

[[folder: Tabletop Games]]
* Whether this applies in ''TabletopGame/{{Scion}}'' is on a case-by-case basis, and usually connects to how the Scion's mortal parents were. In general, the worse a Scion's mortal family, the more likely they'll be relieved to discover they had a divine parent. Most of the sample characters are still a little bitter at the circumstances; in the opening fiction for ''Scion: God'', Donnie Rhodes makes a point of barging in on his mother (Aphrodite - a rare glorified ''egg'' donor) to inform her that his (mortal) father is dead - and showing no surprise at her lack of reaction.
* In both of Creator/WhiteWolf's [[TabletopGame/WerewolfTheApocalypse Werewolf]] [[TabletopGame/WerewolfTheForsaken lines]], it's noted that werewolves aren't typically the most involved parents, given that they've often got duties that put them in the line of fire on a constant basis, a feeling about them that unsettles normal humans, and Rage that's constantly threatening to boil over. The games also note that this isn't exactly a guilt-free matter for the parents - as they've got wolf-life aspects in culture and mindset, they feel a need to protect their mate and young. It's just that sometimes, the best form of protection involves staying away, no matter how much that sucks.

[[folder: Video Games]]
* Cernd in ''VideoGame/BaldursGate 2'' is eventually revealed to have left his wife with child when [[StealthPun he heeded the call of nature]] and became a druid (it's implied that he knew this, which was why he left her). He has a sidequest which involves retrieving said child from its abusive stepfather (who probably killed Cernd's wife)... And then leaving it to be raised by druids. [[spoiler:If you keep Cernd in your party through ''Throne of Bhaal'', his [[WhereAreTheyNowEpilogue character epilogue]] reveals that his son grows up a bitter, bitter person since his father is always busy with being a druid. The son becomes an EvilSorcerer who threatens large parts of Faerun, and Cernd tries to stop him: The two fight each other to the death.]]
* Averted in ''VideoGame/{{Contrast}}'' where despite Vincenzo being Didi's biological father, she loves her stepfather Johnny more.

[[folder: Webcomic]]
* ''Webcomic/{{Drowtales}}'' features a matriarchal society that views men as the lesser gender, due in part because drow females are generally larger and stronger than their male counterparts. Noble classes place heavy importance on producing strong female heirs and as such men are often bartered and traded between clans to mate with women of other clans to produce strong children. Depending on the couple and the circumstances it may either be this trope or ChosenConceptionPartner. One clan in the setting forgoes this and is practicing methods and experiments to negate the need for a man and allow for HomosexualReproduction.

[[folder:Western Animation]]
* Averted twice, first by the father, then by the son on ''WesternAnimation/YoungJustice''. Superman is not at all happy that someone cloned him, and refuses to claim responsibility for Superboy. If you keep up on the comics, you know that [[spoiler: Superboy has two fathers, and the other is Lex Luthor]]. And when he shows up, he clearly wants to instigate this kind of relationship with Superboy ([[ManipulativeBastard for his own ends, as you'd expect]]) and Superboy turns him down flat. [[spoiler: The trope is later played straight to a point when Superman accepts Superboy as a little brother, a relationship both of them are okay with after their initial awkwardness.]]
** Subverted by [[spoiler:Black Manta]] and Aqualad. Aqualad appears to have this relationship with him, even though he did nothing (worse, he's attacked and tried to kill Aqualad in the past) to have that respect. However, it's made clear in "Depths" that Aqualad is only using him to get closer to [[BigBad The Light]], and refers to him quite coldly as "my ''biological'' father", showing that the attachment is fake. Also played with in that [[spoiler:Manta's]] attachment to him seems to be genuine given the distress he shows when [[spoiler:Kaldur gets {{mind rape}}d into catatonia by Miss Martian]] and Kaldur himself [[spoiler:shows regret when he drops the act and takes his father down near the end of the season]].
* Subverted in ''WesternAnimation/TheSimpsons'' when it is revealed that Barney Gumble is the sole donor to Springfields sperm bank, resulting in a lot of burping babies.
** Also subverted in another episode, where it is revealed that Homer donated to an out-of-town sperm bank and that many of the customers had Homer-esque babies.
* Averted in ''WesternAnimation/{{Adventure Time}}'' when Finn finds out his human father is alive and trapped in the Crystal Citadel as a prisoner/criminal in an alternate dimension. Despite having a caring (if demanding) stepfather, Finn is determined to find and form a relationship with his biological one, probably thinking he had a good reason for not being in his life. Turns out his father, Martin, is a immature jerk who treats Finn's attempts at emotional bonding with little more than irritation, only baiting him with paternal affection when it leads to him getting what he wants. In the end, Martin completely abandons Finn with a group of other escaped interdimensional convicts, directly causing Finn to lose his arm and leaving him and Jake alone to deal and nearly get killed by the Lich. Needless to say, Finn is left utterly devastated after all this.
* ''WesternAnimation/FamilyGuy'' had a bit involving Superman's x-ray vision revealing a fetus growing in Lois, prompting him to bail on her with the excuse that he "forgot something on Krypton". Non-canon prequel?

[[folder: Real Life ]]
* Poor Matthew Roberts, the man who made headlines when he found out his biological father ''might'' be UsefulNotes/CharlesManson (not only that, but according to his mother, he was [[ChildByRape conceived by rape]]). When Manson found out, he sent him a letter saying "I didn't know my father either" which all things considered [[FalseReassurance is not particularly comforting]].
* UsefulNotes/GeraldFord's father, Leslie Lynch King, was essentially like this. They only met once, and all that King had to give the boy was ten dollars to get "something he normally wouldn't get". And that is why Gerald legally changed his name to that of his stepfather.
* A Dutch TV show, which aired in 2011, attempts to take (voluntary) DNA tests of everyone who has donated to, or was conceived by, artificial insemination.
* The purpose of family law is in significant part avoiding this. In most countries, the law has expansive powers to take money from fathers to support their children, and fathers are encouraged to see their children. This doesn't always happen, of course, but technology has made it harder than ever for fathers to avoid their responsibilities.
