King of the Hill is one of the best adult animated shows that ran for 13 seasons from 1997 to 2009. It followed the everyday life of Hank Hill, a propane salesman, and the lives of his friends and in Arlington, Texas. But you already knew that. You’re here for the good stuff, like all of the crazy King of the Hill  facts, and things you never noticed about the show. Like how Hank isn’t Bobby’s father… 


Sure, there are plenty of awesome Hank and Bobby moments, but have you ever noticed that Bobby looks exactly like Bill? Or that he and Hank never seem to see eye to eye? What about that time Bill passed on his secret “ recipe?” The facts have been right in front of your face all along. Check out all the evidence that Hank is not Bobby’s father and vote up the best reasons! 

Bill Admits To Sleeping With Peggy And Hank Dismisses It

Late in the series, Bill actually admits to sleeping with Peggy. In the episode titled “Hank’s On Board,” the gang find themselves in a pretty sticky situation. They’re stranded at sea and worried that they won’t survive, so in a moment of panic, they all start revealing their deepest, darkest secrets.
After everyone spills their beans, Bill is the last to “get something off his chest.” He says, “I have a confession, too, Hank. In a moment of weakness, on a dark rainy night, I slept with Peggy.” Hank simply writes it off and says, “No, you didn’t, Bill,” and that was the end of it. Some fans believe this is another example of everyone ignoring what they already know.

Bobby Has An Obvious Physical Likeness To Bill And Dissimilarity To Hank

Bobby and Bill look exactly alike. They’re both overweight, they’re both short, and they both have huge appetites. Bobby and Hank have almost nothing in common, and although Bobby does eventually start taking interest in things like hunting and grilling, his physical attributes look nothing like Hank’s.

Bill Passes On The Dauterive Family Recipe To Bobby To Keep The Family Tradition Alive

In the episode “Blood and Sauce,” Bill becomes depressed after learning that Dale is passing his legacy onto young Joseph because Bill has no one like that. Sparked by a confrontation with Hank about how he doesn’t like grilling, Bobby offers to help Bill prepare his secret family recipe for a cookout.
After getting in an argument with his brother about preserving the family name, Bill decides to teach Bobby how to make his secret family recipe “so that his family name will be remembered.”

The Parallel Between The Hills And The Redcorns Is The Creator’s Joke On The Audience

A user on the King of the Hill Wikia suggested a theory that the show creators have been in on the joke the whole time, and that they’ve been using the between Dale, Joseph, and John Redcorn as a joke. The fans “are meant to laugh at Dale’s cluelessness, but miss a similar situation themselves.”

Peggy Resents Bill

If Bill is Bobby’s father, it would have caused a lot of stress between him and Peggy. Obviously, Bill still pines for her, but Peggy is disgusted and irritated with Bill at nearly every opportunity, which is kind of odd considering what a nice guy he is. Reddit user Zdog1111 thinks Peggy “would see it as a really bad part in her past life and take it out on him.”

Bill Has A Recurring Crush On Peggy

Bill’s interest in Peggy is built into his character description. “Bill has an obsessive crush on Peggy, and frequently makes bumbling, inappropriate remarks about her. Although Bill always speaks highly of Peggy and looks to her as the epitome of desire.” Countless episodes feature Bill pining for Peggy, so much so that Hank isn’t even bothered by it anymore.

Bill And Bobby Are Always Bonding

Bill and Bobby have a unique . Bill always wanted , but “never had any” before his divorce, and is too much of a CHUD to find a new wife. All throughout the series, fans see little snippets of Bill and Bobby becoming pals and bonding.
For example, take the episode called “It Came From The Garage,” where Bill helps Bobby in a boat-building competition because Hank is afraid of a bat living in the garage.

Peggy Admits That She Slept With Someone Other Than Hank

In the episode titled, “Luanne Virgin 2.0,” Peggy reveals (under some pretty aggressive circumstances) that she slept with someone other than Hank. She writes it off as a quick fling with “her very best male friend, Wayne Trotter.” She claims that Wayne was actually and nothing further happened between the two.
However, some fans believe that this explanation is a lie and that Peggy was simply trying to cover up the truth.

Bill Is Bobby’s Dad, But Cotton Is Still His Grandfather

Reddit user skaloop has a hunch that Cotton is actually Bill’s father, although they keep it secret on the show. This would make Hank and Bill half-brothers, and explain why Bobby looks so much like both Bill and a young Cotton. This could also explain why Cotton seems to favor Bill over Hank.

Bill Isn’t Mentally Capable Of Being A Father

Dale discovers that during his time in the army, Bill was subject to an experimental procedure known as Operation: Infinite Walrus. The project was designed to create a hybrid super-soldier. While Dale believes that this drug caused Bill to gain weight and start growing more body hair, it is revealed that Bill was merely given a placebo.
But what if Bill wasn’t given a placebo, and the government simply didn’t want to pay the medical expenses associated with botching a soldier’s brain? Bill routinely displays behaviors found in those with excessively low IQs. What if Peggy, concerned that Bill lacked the mental capacity to be a father, convinced Bill to let Hank raise the boy instead?

Hank Is Autistic And Everyone Is Trying To Protect Him

Look, there’s no arguing that Hank Hill is a unique individual – he’s got a lot of serious quirks. One fanthinks those quirks might be a manifestation of severe high-functioning autism. Think about it: he’s obsessed with propane, he’s emotionally distant, he’s very uncomfortable discussing , and he rarely expresses emotion.
If Hank is living with autism, maybe the rest of Arlen knows he’s not Bobby’s father, but keeps it a secret because they know he couldn’t handle it.

Hank Is A Closeted Homosexual

There’s actually a ton of theories surrounding the idea that Hank Hill is secretly , not to mention a whole boatload of fanfic and Rule 34 posts… Here is Redditor RoseWolfie‘s take on the subject:
“Hank is a closet homosexual. Growing up with his manly man father and [surrounded by] Christian beliefs caused him to suppress that side of himself. He did it so much he would reject anything he considered flamboyant, like feelings and stage performances. He married Peggy, mainly cause of her acceptance of him, but subconsciously because she is the closest he will ever come to a male on his own. Her large feet, male structure, and boyish personality made it easy to accept her as his life partner. As well, it took the pressure off of him to find a mate. He still rarely touches her, only when sexual need reaches a point. Most likely he never reaches a full orgasm.”
