John Redcorn is Older Than He LooksThe epileptic tree is that: He is Dale's grandfather. Making Joseph his uncle.
Kahn and Minh speak primarily in Laotian, but it is dubbed for the audienceThis would explain why they can often, very loudly and to the main characters' faces, call them horrible names and never get called out on it. Also, whenever Kahn and Minh are fighting and the audience is given another character's perspective of the argument, they are almost always speaking Laotian.
John Redcorn is the time travelling reincarnation and/or genetically altered version of DaleOur Dale is aware of this fact and this is why he considers Joseph his son. He hides this from the others by feigning ignorance and saying John Redcorn is gay. Not even John "alternate Dale" Redcorn knows that Dale knows.
Hank has other half-brothers.Including Hal, the guy who was identical to Hank and made Dale and Bill jealous. Either that or Hal is Tom Anderson's son, who is also Cotton's half-brother.
Beavis and Butt-head happens in the future of King of the Hill.It was never said, but the real reason "King of the Hill" ended was because Hank stopped going on adventures, he got tired of his life. After years of this happening, Peggy became tired of living with him and divorced him. Hank felt so bad from the experience, he moved away. Once he grew old, he met a woman who liked being calm and relaxed named Ms. Anderson. Since Hank didn't feel like a man any more, he took her last name. After living like this for a while, the events in "Beavis and Butt-Head" took place.
The last episode will be about Hank trying to solve a wrong situation (like any other episode), yet it turns out that he was wrong.After that, we are treated to flash forwards of Hank being wrong time after time, and Bobby is right. Hey, at least the boy will finally be right, as Hank wants him to be.
Boomhauer's job as a Texas Ranger is what has been keeping Dale, Buck, and several other characters out of prisonHe has to have some sort of pull with the police, since he is one of them. It's the only logical explanation for how Buck hasn't been locked in state prison and Dale isn't in a mental hospital. Seriously, the crap Dale and Buck have pulled would land a person in prison.
Hank's family tree (including only Cotton, unrelated Bill, and their offspring):
Dale Gribble has known that Joseph isn't his son since Day One, and has created his own fantasy world to live in as a result.Furthermore, he also knows about Nancy and John Redcorn's affair (probably from the start). But his fragile mental state (caused by the refusal to accept the truth about his father's sexuality despite the evidence being right there in front of him and the normal traumas associated with being a skinny, dateless nerd in Texas of all places) simply couldn't handle the depths of his wife's deception and the realization that his greatest fear had come true (that a 'goddess' like Nancy could never love someone like him). So he ignored all the evidence in front of him and created a reality for himself as a badass bounty hunter/mercenary who was desirable to women and feared by men, with a son destined to grow up in his own image. And as he realized that more and more people knew the truth about his secret shame and the lies of his marriage, he sunk even deeper into this world and eventually lost himself entirely. He used government conspiracies and alien manipulations to explain away the discrepancies in his life, and used these paranoid fantasies as an excuse to lock himself away from the rest of the world at the drop of a hat anytime his subconscious mind attempted to force him to accept the truth. Becoming a pest exterminator allowed Dale to take out the hidden rage and buried frustrations he has about his sad existence without running the risk of a physical confrontation with a human that he would surely lose, and along with his bizarre 'experimentations' (another attempt to explain away Joseph's paternity by manipulating science itself) creates yet another barrier between himself and the rest of the world. And when he was forced to temporarily quit exterminating and had to exist in said real world, his hatred was manifested in the cold dispatch of his duties as the Stic-Tek 'hatchet man', the complete disregard of his family and friends and implied rough, angry sex with his wife. Plus, his refusal to use protective gear while using poisons, his haphazard use of firearms and artillery and other reckless behavior are clearly subconscious cries for help and indicative of a death wish. And you thought Bill was screwed up!
Joseph really is Dale's sonThrough the magic of recessive genes,Dale's Indian blood shines through.
Hank Hill has high fuctioning autism or Asperger's
Bill is Bobby's father.Bobby looks a little more like Bill than Hank, and Hank has a medical condition that affects his fertility. Throw in Bill's constant obsession with Peggy and the answer is obvious. Hank is actually sterile, and Bill had an affair with Peggy that resulted in Bobby. The parallel with Dale, Joseph, and John Redcorn is the creator's joke on the audience - they're meant to laugh at Dale's cluelessness but miss a similar situation themselves.
Hank is Blessed with SuckHe is destined to win (nearly) all social arguments. Unfortunately, that requires that everyone who enters his life is plainly wrong. He's destined to never meet a reasonable roleplayer who sees gaming as a hobby instead of something that requires drinking blood. Never to see a soccer coach who treats the sport well. Never to meet a liberal who makes sense. Hank Hill is doomed to forever encounter idiots and lunatics.
In relation to the theory above, Arlen is Blessed with Suck, not Hank.Think about it. Sure, people are a little kooky outside Arlen, but why are the worst offenders in Arlen? And why are people at their worst there? Some possible theories:
The Manger Babies are made of a material that causes brain damageHow else can Luanne get stupider every episode since getting them?
Dale's grandmother really is Jamaican.This would explain both his nonplussed reaction at Nancy giving birth to a child with dark skin, and his lack of overtly racist views despite his Right Wing Militia Fanatic leanings.
Octavio used to work in a mental asylumBut one fateful Halloween night a giant, mute psychopath broke out and killed him... or so it seemed. After the killer escaped, he got up and ran away to Texas, where he took on a new identity.
The real last episode will have Hank and Peggy witness a murderThey'll be placed in the witness protection program, at which point they'll be moved to a new town, where they end up living near to a pair of half-wit teenagers.
The show is actually the future of Beavis And Butthead.Think about it. Hank is a descendant of Daria, having gained a bit of her mind. Just like Daria's family, the Hills have a few Quinns, Helens and Jakes. (Bobby, Cotton, Bobby, respectively. YMMV) Just as Daria's world was filled with idiotic people, so is Hank's world. His friends are related to the Fashion Club or Beavis and/or Butthead. I wouldn't be surprised if Boomhauer is Beavis's son.
One of Bobby's classmates is an illegitimate son of Boomhauer.
Gerald Goode is another of Cotton's illegitimate sons
The whole series is the delusion of as he rots in federal prison.
Bobby Hill grows up as a social worker for Arlen.On the last episode in the series, Bobby has an experience with girls around the end that influences him to think higher and more aware of himself. This particular event makes Hank say more than three or four words of encouragement to Bobby. Much later in his life, he considers taking a position at a social workers group for troubled adults and teenagers. He also marries Connie Junior, letting her be his assistant.
Bill became the opposite of a remembered hero due to Karma.Bill was in the army once, so he has a badge of honor on his end. But unhealthy habits like dredging over an ex for years had turned him from recognized and honored person to a bummer of epic proportions.
Boomhauer suffers from a severe case of OCD.To put it more likely, a rare case of OCD that enforces strict vocalization of a sentence or a word. When he was very young, Boom was pressured to read at a rate beyond the normal for a child, to the point where a bad habit of speeding up words became an indent to his mental establishment. This can be proven by the fact that none of his youth is ever brought up except for College and High school. I can conclude it as unpleasant in a way.
Hank really is richHe's just extremely good at keeping it a secret so Bobby can learn the value of money and not waste the fortune when Bobby inherits it.
Aliens overwrote John Redcorn's genetic material with Dale'sJohn Redcorn, being a attractive sample of humanity, is likely to get around, but with Dale's DNA being spread around, the future generation is likely to be just as weak as Dale. With a few hundred generations the population is ripe for an alien invasion. Boomhauer is also part of their plan due to him really getting around.
Peggy's flanderization into a Small Name, Big Ego has an in-universe justification: it was the result of brain damage she sustained in the sky diving accident.In seasons 1-3, she was a friendly woman with only occasional ego problems. At the end of season 3, she has the accident. From season 4 onward, she's dramatically less sympathetic and her ego and cluelessness are suddenly her most dominant traits. Coincidence? I think not.
John Redcorn is really an alien.So technically Joseph really is part alien.
Luanne's flanderization also has an in-universe justification: brain damage sustained in the Mega-lo Mart explosion.Note that one of her very first acts after said explosion is to take pictures of CNN broadcasts in an attempt to become a photojournalist... this could be considered her first really stupid act in the show.
Bobby is deadSometime after his 13th birthday, or after breaking up with Connie, Bobby died. This explains why he and everyone remain the same age, even though years are said to have passed: the rest of the series is his dying dream. Of course, one could argue this for any character (except perhaps Dale and Bill, for obvious reasons), but it fits when you consider that before he turned 13, almost everything Bobby did was against Hank's favor, but shortly after, Hank began to accept at least some of Bobby's shortcomings. The final episode, in which Bobby and Hank discovered common ground with meat, was Bobby's very last moments, dying in the belief he and his father had finally found a relatable subject.
Buckley is imagining the show post explosionHe sees the people he knew get stupider and meaner as he's closer to dying and the Buckley's angel ep is him wanting to guest star.
Bobby is an orphanHank and Luanne died in the Mega-Lo Explosion. Peggy was despondent, especially her wedding anniversary, so Bobby got her a ski-diving lesson as a present. And she died. Either Tillie or Cotton got custody of Bobby and he communicates long distance with Joseph and Connie, while probably being miserable and escapeing to daydreaming about what may have happened if they were alive. The show's later Seasonal Rot is him finding something to keep him happy and leaving behind the fantasy.
Nancy is losing her hair because of the pressure of not telling Dale the truth about Joseph's father
Beavis and Butthead grew up into Boomhauer and DaleOkay, first, just look physically at the characters. Boomhauer looks like Beavis. He speaks incoherently (as Beavis often did). We have no frame of reference for when Beavis and Butthead took place. We simply know they were in their early teens, possibly in junior high or high school. We never saw the school year end on Beavis and Butthead, it easily could have been one school year, after which Beavis matured, took up playing football and could have evolved, and grew into the man wee see in Hank's flashbacks. Dale could be an older Butthead, he has similar facial features and hair color. As with Beavis above, we don't know how long the timeline of Beavis and Butthead is, or even how old the boys actually were. They could have met Hank, decided to eschew their childish nicknames and started going by their real names, eventually gone out for football and become the young men we see in flashbacks with Hank and Cotton. Beavis and Butthead also takes place in Texas (though in the fictional town of Highland IIRC). Hell, it's even possible that Beavis and Butthead were taken from their poverty-stricken, neglectful parents by protective services and placed into adoptive care in Arlen.
Bill dated Peggy before Peggy and Hank got married.Peggy dumped Bill, and after that, Bill never really had another successful romantic relationship. That's the reason he still is obsessed with Peggy, and he only stays friends with Hank so he might have a chance to get closer to Peggy. Peggy is sick of Bill's obsession, with is why she hates him.
The story takes place from Hank's point of view, though he doesn't directly narrate.
Peggy has gone to Paradise Cove beforeHow else would she bring up the name of the nude beach so fast in "Sug Night"? And later when she disrobed, there were no tan lines to be seen on her.
Buck Strickland was once as great as Hank treats him
Dale knows about Nancy's affair with John Redcorn, but pretends to be ignorant about it.Dale's always making up stories about how Joseph came from aliens because he doesn't want Joseph to know about the truth.
Hank was not always the honest propane salesman or great football player we knew him as.Basically, you know that flashback to the night when he got drunk and had Bill's name tattooed on the back of his head? He must have been acting like that all the time up until he met Buck Strickland. People have simply never forgiven or forgotten. There is no other logical explanation for why absolutely every person he knows expects the worst from him at all times.
Cotton played a heavy hand in the men Dale, Bill and Boomhauer grew into.Dale is president of the gun club and has a large collection, Boomhauer is basically a man-whore and Bill joined the army with the hopes of becoming a war hero. There are exactly three things Cotton loves: Guns, sex and war. Cotton rubbed off on each of them in a different way.
Topsy is Beavis' Grandfather.Being a Military man that served in WWII, Topsy really got around. In the midst of that, he knocked up a loose woman that ended up being Beavis' Grandmother. Said illegitimate child was Beavis' slut mother that got knocked up by the ex-Motley Crue roadie turned drifter. Beavis comes from multiple generations out of wedlock. On top of that, Topsy does have some similarities to Beavis. And as for the differences, well, there is a theory that there is uranium in the drinking water in Highland.
The old monk is a time travelling reincarnation of Bobby/SanglugWhen Bobby was thought to be Lama Sanglug, an old monk was brought in to decide if he really was. In the end, Bobby chooses to be with Connie rather than risk becoming the Lama. The old monk chooses to accept Bobby's decision, despite all signs pointing at Bobby being Sanglug. He adds whistfully, while watching Bobby and Connie walk away, "It's my choice, and I made it." If Bobby really was Sanglug, then he would be reincarnated again after he dies, this time coming back as a monk several decades before Bobby was born. When the monk arrives in Arlen, he remembers his time as Bobby and recognizes the moment when Bobby chose Connie over Lama-hood.
Cotton and Tilly were cousins or even closer...Cotton's other confirmed sons look at least somewhat like Hank, if not damned close, and in WMG's above, so do some of his theorized sons. Yet Cotton had these sons by other women, including a Japanese lady, and Hank's looks seem to take more after Tilly than Cotton. The solution is that Cotton, somewhat broken by the war, was forced to marry his first cousin, with possible legal fudging if the laws in Texas at that time didn't allow for it. However, given how much these other sons also look like Tilly, it is even possible that one of their fathers had an affair with one of their mothers, leading to some squick and a possible explanation for the closeness and those patches of mental instability outside the Platters.
Joe Sixpack is based on Hoyt Platter, Luanne's father.He does evil like "not calling you on your birthday" and "throwing beer bottles at your head".. Luanne sounded like she was speaking from personal experience.
Cotton made up all his claims to fame.With the way he's always bragging how his war heroics the truth is and he knows it that it's nothing more than a load of hogwash. He didn't kill fifty men, he didn't even kill five men. Odds are he was in a lowly position in the army and put on cook duty nowhere near the frontlines and itching for glory one day and overhearing from the others a Japanese squad possibly close by grabbed a gun and charged thinking to become a hero and walked right into a minetrap destroying his shins and giving himself and the others away resulting in them being attacked. The rest of his squad came and they and the Japanese in the battle died dragging his sorry carcass out of there and when reinforcements came and saw him the only survivor he hastily grabbed a gun and acted like he was shooting and claimed they were ambushed and he killed all the Japanese so he wouldn't be dishonorable discharged (lucky if got that) for getting his entire platoon and comrades killed cause of his Glory Hound desires.
Dale knows about the affair, but says nothing because he's incapable of producing children.He knows that Joseph isn't his biological son, but loves him nonetheless. He pretends to be ignorant about the whole thing because he fears that Nancy will leave, and take Joseph with her, if she knew that he knew. John Redcorn has expressed a desire to take part in raising Joseph, so that only increases the risk. Nancy doesn't tell Dale anything because she doesn't want to hurt him, but if she did tell him, that pressure would go away and without that pressure, she doesn't have as much reason to stick around.
Hank and others don't tell Dale about Nancy's affair because there's a strong risk he would become suicidal.There's an episode where Dale goes into the Despair Event Horizon when he finds out that Hank played a silly prank on him by stealing his lawnmower and sending joke random notes. Dale doesn't trust many people so if he goes into that with Hank, imagine what would happen if he learned that Nancy was betraying him for over 13 years. Hank and others know this, but they agreed to say nothing because they don't want him attempting suicide.
Bobby enlists in the military after finishing High School and becomes a more decorated hero than Cotton.Bobby is known to be a top-notch marksman. Given a few years and basic training, he could easily iron out into a good soldier. When pushed, he's shown some impressive determination (particularly when he stole the Belton armadillo and when Cotton put him in the hole.). It would also be hilarious for a Friendly Sniper to cap off a shot with "Vat are you talking about?"
