These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Basically, anything below Hard Rock tends to "suck," but they do make exceptions. Radiohead's "Fake Plastic Trees" was praised by Beavis, as he likes to "mellow out to this song."
Beavis: Sometimes if I have a boner that won't go down, I listen to this kind of music.
Like in it's sister show, King of the Hill, people in the military are rarely depicted in a positive light. Buzzcut is a violent, abusive sociopath. An episode of The Revival had a military officer bluntly say that they accept drop-outs and delinquents and were too incompetent to notice the titular characters sneaking in a restricted area and piloting a drone.
Alternative Character Interpretation: Interesting in the case of Coach Buzzcut. Although he is one of the main antagonists of the show, one could also argue that he is kind of a Hero Antagonist, because Beavis and Butthead are often extremely unpleasant in any situation. Although this is challenged a bit by his aggressive behavior, tendency to threaten anyone with bodily harm, and him turning a bunch of students onto a new student in "Young, Gifted & Crude" as seen in Kick the Dog below.
Also, Beavis. There are numerous hints dropped throughout the original series that Beavis, despite being a thick-headed pain in the ass to most everyone he meets, actually has a heart in there somewhere, but Butthead is too much of an abusive bad influence for him to even remotely realize that potential. He even makes an effort to be polite to people, despite his lack of social skills ("Hey how's it goin'?").
The duo themselves. Are they a pair of morons who do not realize that their antics put others in danger because they are too stupid to realize their actions or are they sociopaths who realize what are they doing is wrong, but don't care? There have been times, mostly during music video segments, where they are smarter than usual.
Awesome Music: The last montage of the final (at the time) episode clip show had a compliation of the two wreaking havoc set to "In the Hall of the Mountain King" with Beavis and Butt-Head's vocal air-guitar riff dubbed over it.
The biggest Ensemble Darkhorse of the show is Beavis's alter-ego, The Great Cornholio. He only appeared in a few episodes and The Movie, but he is one of the most popular and funny characters in the entire show.
Growing the Beard: In the early episodes, the duo didn't go through the range of jokes as later seasons, and most of the time they were just playing pranks or causing all around mischief. When the show started to get popular (and when MTV got scared that kids may be imitating the duo's destructive behavior), their personalities changed into the way most people recognize them now by. Of course, this made everything a hell of a lot funnier.
Which is funny, because their earlier music video reviews were very little except jabs or praise for the band/artist. Their later reviews had a more intellectual insight, implying that the characters are savants.
Most agree that the revival is even better than where it left off, mostly thanks to Mike Judge being able to apply a lot more years of experience on perfecting the comedy.
Hilarious in Hindsight: The 2005 MTV Video Music Awards, in which Beavis and Butt-Head pop up from time to time, urging viewers to put them back on the air by voting for them in the MTV Viewer's Choice Award (not realising they're not a voting option).
This poster◊ released several years ago more or less captured what the fourth episode, Holy Cornholio, is going to be about.
Ho Yay: Huh huh huh huh, Todd's cool. (floating hearts)
At the end of "Beware of the Butt", the duo is hung from the marquee butt-naked, leading Butt-Head to make comments on Beavis' rear end.
Beavis: Why are you so interested in my butt? Butt-Head: Uhhh... have you heard the new Gwar album?
In "Sporting Goods", the two try on athletic supporters in the same dressing room.
In "Baby Makes Uh, Three", Beavis and Butt-Head are partners to take care of a flour sack for their health class. Buzzcut justifies this by telling them that with the increase of homosexual couples adopting children, it makes the project more realistic. Surprisingly, the duo makes no comment.
This exchange from the tie-in book "This Book Sucks":
Beavis: Hey, Butt-Head. Do you think you'll ever, like, get married? Butt-Head: Uh, are you proposing, dude? Beavis: No. Butt-Head: That's OK, I'd only marry somebody dumb anyway. Huh huh.
The Ho Yay between the two is parodied in an advert for the third volume of The Mike Judge Collection done in the style of Brokeback Mountain.
Let's face it: it's their only hope of getting any.
In the movie, Beavis and Butt-Head mistakenly believe that Dallas is paying them to have sex with her husband, Muddy. While Butt-Head flatly rejects the offer, Beavis responds with "I don't know, Butt-Head; that's a lot of money. Maybe if we just close our eyes and pretend that it's a chick..."
Misaimed Fandom: Show garners a cult following of the very slack-jawed teen morons that the show attempts to satirize.
Moral Event Horizon: The Crazy Old Farmer / Janitor crosses the line with the attempted murder of Beavis in "Cow Tipping".
Buzzcut crossed it in Young, Gifted, and Crude by allowing his class to beat up a new student.
Principle Mc Vicker (with Buzzcut's help) crossed it in Wet Behind the Rears where they set up a fire drill after gym class just to make the boys go outside in their underwear (or naked as they had intended had they not argued with Buzzcut). The boys didn't even do anything to provoke them in that episode.
Nausea Fuel: Beavis and Butthead as "werewolves" in "Werewolves of Highland" note The result of being bitten by a bum with numerous STDs whom they mistook as a werewolf.
"Beaverly Buttbillies" features the two believing they struck oil in the show's take on the "(dumb) character mistakes sewer discharges for oil" plot. And they get covered in the stuff.
"I Dream of Beavis" shows Beavis becoming convinced that a dead, decaying rat in a bottle is a genie. And then he brings it to school...
"Sick" has Beavis and Butt-Head spend most of the episode with snot dripping from their noses (including a lovely close-up of Butt-Head eating cheese doodles with snot not too far from his mouth) and multiple scenes of Beavis blowing snot out of his nose.
Nightmare Fuel: "Breakdown" is truly a disturbing episode where Beavis and Butt-Head's inane laughter over the intercom finally drives McVicker to suffer a terrible mental breakdown and things only worsen when they visit him at the mental hospital. Then the episode ends with ominous music as their indifferent laughter begins to drive Van Driessen insane...
The two pilot episodes of the series are truly disturbing and unrealistic too, considering some Nightmare Face that the duo does, and some deaths in the same episodes. Still, they are considered as Negative Continuity.
Butthead often comes into this territory. While he is more of a Broken Base, him is often hated by Beavis fans for his poor treatment of Beavis.
Social Services Does Not Exist: Beavis and Butthead are teenagers, who appears to live on their own, which begs the question on how could no one considered checking on their home life.
Squick: Many instances within this series, such as the classic pre-series segment about a monster truck arena getting flooded with crap. Or Beavis' grievous dog bite wound and seeing individuals poke the exposed bone.
Word of warning, "Nose Bleed" is not for the squeamish.
Happens in-verse when Beavis and Butt-Head convince a female instructor and Van Driessen to let them watch an educational film about female reproduction, only to be utterly Squicked out when it comes to the part about giving birth.
Tear Jerker: The duo meeting their fathers for the first time in Do America. The fact that they woke up the following morning after bonding at the campfire only to see that they left while they were still asleep makes it more heartbreaking. Granted, neither the duo nor their fathers knew who they were, but anyone who has suffered from Parental Abandonment could relate.
A notable example is in 'Vidiots' when the two go to a video dating service, Beavis gives a fake name to the lady working there (Heraldo, which she interprets as Mexican), and she mistakes Beavis' sexual answers to her questions as romantic while Butt-head is doing his video, and tries calling Beavis, only for Butt-head to hang up on her, shortly after Beavis answers the door for a Woman asking to turn on "The pleasure machine" (Butt-head, as he mentioned twice in his video), Beavis thinks she is talking about the TV and slams the door on her.
What Do You Mean, It's Not for Kids?: Lost in the tragedy of a child burning down a house, or part of a house, is the question Why is a child watching Beavis and Butthead?!? It's animation, right? Must be OK for the children, then. The child in question watched the show because his babysitter let him watch it, but who cares? Moral Guardians in America certainly didn't.
You may remember a speech similar to that from Teen Talk.
Stewart. He genuinely thinks Beavis and Butt-head are his friends, he keeps trusting and forgiving them and worrying about their safety no matter how many times they screw him over. Not to mention his overprotective mom and his dad trying to pin the blame on him to save his own skin more than once.
