Banned Episode: 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 Beavis and Butt-Head 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.
The Cameo: While Daria herself is absent from the revived show thus far, her sister Quinn (or somebody who looks a lot like her) can be seen in the background in a few scenes at the school.
Fan Nickname: "Buffcoat and Beaver," after a confused politician refers to them as such while railing against them publicly.
On a King of the Hill documentary on how the show (King of the Hill, not B&B) 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."
The series also had some appearances by comedian Bobcat Goldthwait, SNL cast member David Spade (on two episodes — one appearance as a guest speaker who tries to teach the class proper etiquette, and another where Beavis and Butthead sell candy for a school fundraiser), and Julián Rebolledo (Daria fans might know him as the voice of the dad, Jake).
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 have recordings from the first time they aired on MTV.
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.
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.
Uncanceled: New episodes debuted in October 2011, but disappeared as soon as they premiered.
What Could Have Been: Had Daria 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.
The relaunched series was initially going to have Beavis and Butt-head as adults. For some reason, it was decided to keep them as teenagers when it finally went into production.
Paramount Pictures originally insisted that the movie should be live-action with former SNL cast members Adam Sandler and David Spade as the title characters. Judge managed to convince them that doing it as animation would be much cheaper and more rewarding for certain scenes.
There were several different ideas for the plot of the movie as well before they settled on the final plot. One idea involved a virus that spreads and slowly turns people into Beavis and Butt-Head clones. Another was a joke concept that Judge came up with where it was an hour and a half real time of the two eating lunch at Burger World.
