The third-season opener "Comedians" featured Beavis trying to juggle flaming newspapers and burning down a comedy club. Because it aired only a month before the Ohio mobile home fire that Beavis and Butt-Head were blamed for, this episode was swiftly pulled out of rotation and later heavily censored.
Other episodes were banned (some of which did return from being banned with content cuts made) for instances of Beavis saying "Fire! Fire!" or flicking a lighter ("Stewart's House", "Kidnapped"), animal cruelty ("Frog Baseball", "Washing the Dog"), inhalant and drug abuse ("Home Improvement", "Way Down Mexico Way") or anything that might be considered poor taste in the aftermath of Columbine and September 11th ("Heroes", "Incognito"). Many of these episodes have aired on Viacom-owned networks overseas unedited.
Exiled from Continuity: Judge is not allowed to use Daria anymore since the show was resurrected, as MTV has stated that they want to keep the character freed up so as to possibly revive her show down the line. During a music video, it is explained that she moved (though Beavis thought she committed suicide), as per the canon of Daria.
"Buffcoat and Beaver," after a confused politician refers to them as such while railing against them publicly.
On a documentary about how King of the Hill was created, Mike Judge says he came up with Boomhauer's distinctive voice after hearing a man's voicemail about how much he hated Beavis and Butt-Head, which he referred to as "Porky's Butthole."
Franchise Zombie: Subjective from a Word of God standpoint; Judge has pretty much stated that the last couple of seasons before the comeback were forced upon him by MTV, who wanted to keep the cash-cow show going. Not that it kept the episodes from still being pretty damn funny in their own right.
And a third of the episodes, which Mike Judge has refused to license to DVD.
Also, all references to Beavis being a pyromaniac ("Fire! Fire! Fire!") were edited out of the show after an incident where a young boy burned down his home. Because the edits were made to the master tapes, the only way you'll see pyromaniac Beavis in the original episodes is if you buy a bootleg DVD set.
Mean Character, Nice Actor: Mike Judge has said that regardless of what Beavis and Butt-Head do to animals, Judge personally thinks cruelty to animals is vile.
Missing Episode: Many. Possibly the rarest is the third-season opener "Comedians", since it features Beavis juggling flaming newspapers and burning down a comedy club. It aired a month before the infamous mobile home fire for which the show was blamed.
"Comedians" was re-aired a few times in a dramatically edited version that has the fire just happen without Beavis's intervention. Far less common were the very early episodes like "Bedpans and Broomsticks" and especially the infamous "Frog Baseball".
So many examples of this trope exist that Mike Judge admits that the master tapes of many of the early episodes probably no longer exist due to the edits.
Name's the Same: Due to the series's trademark overuse of crude humor, there are a disproportionate amount of people named "Dick" in Highland. They include guidance counselor Dick Gaylord, meteorologist Dick Jackman, Sergeant Dick "The Rooster" Leakey, as well as one of Tom Anderson's old war buddies.
No Dub for You: Unlike with the original series, the reboot wasn't dubbed in any foreign country when it was broadcasted.
Old Shame: Much like how Trey and Matt feel about the early seasons of their show, Mike Judge hates most of the very early episodes of the show due to the very choppy animation and obvious humor compared to later seasons. He also hates some of the episodes that incorporate fantastical elements into them. Because of this, a great deal of the episodes from the show have not been released on DVD.
Screwed by the Network: Canada's MTV quickly replaced the revived series with Jersey Shore reruns, occasionally airing the episodes at ridiculous hours of the night.
Talking to Himself: Mike Judge voiced many recurring characters as well as Beavis and Butt-Head themselves, including Tom Anderson using the voice that would later be used for (and associated with) Hank Hill.
Throw It In: At the beginning of Nina Hagen's "Herman Was His Name", Mike Judge flubs a line as Beavis:
Beavis: Whoa, that's a bigass skull, Beavis—I mean, Butt-Head.
Uncanceled: New episodes debuted in October 2011, but disappeared as soon as they premiered.
Unintentional Period Piece: The show's depiction of slacker culture and metalhead teenagers plants it firmly in the mid-90's. While the reboot tried hard to modernize the duo, even retconning a few of their initial traits for this purposenote In the 1993-1997 series, video games are depicted as a "nerd" hobby Stewart is into. While, in the reboot, both Beavis and Butt-Head are fans of games like Grand Theft Auto and Call Of Duty, it still couldn't escape the show's blatant "grunge era" roots. Though, to be fair, the reboot was very clearly made for people who were fans the series in its heyday, rather than potential newcomers.
If Daria had not been a ratings and critical success from episode one, Glenn Eichler has stated that MTV would have most likely have forced him to incorporate Beavis and Butt-Head into the show to boost ratings.
Writer Revolt: "Lightning Strikes"note in which Beavis and Butt-Head wind up in the hospital after imitating a documentary about Benjamin Franklin but a visiting reporter can't understand how an educational show could be a bad influence and concludes that they must've been watching music videos instead. was written in a direct response to the trailer house fire incident that the creators were blamed for.
