On March 8, 1993, Beavis and Butt-head made its debut on MTV—to the delight of young viewers, and the annoyance of their parents. While some people considered it the end of the civilized world, TIME Magazine critic Kurt Andersen lauded its irreverence, writing that it “may be the bravest show ever run on national television.”

From its original 200-episode run to the books (yes, plural), movie, and soundtrack it inspired—plus its brief return in 2011—Beavis and Butt-head has not lost any of its original charm. With the recent announcement that the series is coming back for two new seasons on Comedy Central, here are some things you might not have known about Mike Judge's animated headbangers.

1. Beavis and Butt-head got their start on Liquid Television.

Mike Judge went from teaching himself animation and playing bass for Anson Funderburgh and the Rockets to having one of his cartoons played on MTV’s animation showcase program Liquid Television in one year’s time. Cartoon short Milton, the origin of the character from his live-action cult classic Office Space, appeared in a 1991 episode. In 1992, Beavis and Butt-head made their loud, violent first impression in his short Frog Baseball. MTV then paid Judge for the rights to the two characters and ordered 65 four-minute cartoons.

2. MTV pulled Beavis and Butt-head from the air shortly after it premiered.

Shortly after greenlighting Beavis and Butt-head, MTV had to halt production. Not because of any controversy, but because Judge and his animation staff couldn’t keep up with the demand for new material, forcing MTV to stop airing the show entirely two weeks after it premiered. It made its return more than six weeks later on May 17th with “Scientific Stuff” and “Good Credit.”

Judge voiced virtually all of the characters on the show and was one of just a handful of people who made up the writing staff. He opted to add to his workload by winging it when it came to Beavis and Butt-head's taste-making opinions on music. Time was saved on the animation for the music video commentaries by having an editor take footage from earlier episodes and sync it up with new mouth positions.

4. Beavis and Butt-head were named after kids that lived in Mike Judge's neighborhood.

Bobby Beavis was “kind of an athletic kid” that lived three blocks from Judge while he was in college, and not similar to the character with the Metallica shirt christened with his surname. There was also a 12-year-old who called himself “Iron Butt” (because he claimed to never get injured from a kick to the posterior) who had a friend called “Butt-head.”

5. All references to fire were permanently removed from Beavis and Butt-head after the show was blamed for a child's death.

In October 1993, a 5-year-old boy set fire to his Ohio home, which killed his 2-year-old sister. Their mother claimed Beavis’s fire-making and blatant spoken love of arson were responsible. MTV’s quick response was to only air the show after 10:30 p.m. and to wipe all fire references from all of the previous episodes—only fans who taped the offending episodes on their VCRs have proof that the word was ever uttered. “Fire” was banned for the rest of the series’ original run, but it was allowed again in 2011.

6. A senator referred to Beavis and Butt-head as "Buffcoat and Beaver."

Soon after the fatal fire accident, Senator Ernest "Fritz" Hollings, a Democrat from South Carolina, spoke at a Senate hearing as chairman of the Senate Commerce, Science and Transportation Committee. Hollings attempted to argue that TV broadcasters needed to be forced to clamp down on their offensive programming and used the most controversial show at the time as a specific example ... or at least he tried to.

7. Prison officials in Oklahoma banned Beavis and Butt-head.

There were also documented reports of South Dakota schools outlawing Beavis and Butt-head-related clothing.

8. Marlon Brando was a Beavis and Butt-head fan.

According to Mike Judge, Johnny Depp told him that Depp and Marlon Brando would imitate Beavis and Butt-head, with Depp as Beavis and Brando as Butt-head. This occurred when the two worked together during 1994’s Don Juan DeMarco.

9. Matt Groening was a fan of Beavis and Butt-head, too.

The creator of The Simpsons claimed that he liked the show because it took “the heat off Bart Simpson being responsible for the downfall of western civilization.”

10. David Letterman was the voice of the Mötley Crüe roadie who might be Butt-head's father in Beavis and Butt-head Do America.

David Letterman was credited as Earl Hofert, which is actually the name of Letterman's uncle. Letterman was a fan of the show and had the Highland teens on The Late Show in 1996 to promote their movie.

11. Beavis almost said something too clever once.

In 1993, Judge told The New York Times that one of the big challenges of the show was to keep the two in character and, therefore, dumb. An original line had Beavis telling his classmates that they had “Beavis envy” because he received a school pass. It was cut because it almost made the 14-year-old with the underbite too smart. In 2011, Judge admitted to “cheating” and probably making them smarter than they are during the music video commentaries.

12. Daria was created with Janeane Garofalo and Darlene Connor in mind.

The character of Daria was created after then-MTV president Judy McGrath expressed concern about the show’s lack of smart or female characters. Garofalo and Sara Gilbert’s Roseanne character were the models for Daria Morgendorffer. Morgendorffer was the maiden name of the show writer David Felton's mother, and was deemed perfect for the new character.

13. It's Butt-head's house that you're usually seeing.

While it isn’t officially canon, Judge responded to a reporter’s assumption that the two were always at Butt-head’s abode by saying he “always imagined” that to be the case.

14. Beavis and Butt-head were featured on the cover of Rolling Stone—three times.

Their first appearance in 1993 ended up being the best-selling issue of the magazine that year.

15. Beavis and Butt-head starred in their own live-action Thanksgiving special with Kurt Loder.

The night before their (first) series finale, “Beavis and Butt-head Are Dead," MTV put Beavis and Butt-head in charge of broadcasting the Thanksgiving Day Parade, then later put them at a dinner table with the veteran MTV News broadcaster. The one-hour special only aired on television once.

16. Beavis and Butt-head ended due to creative burnout.

Toward the end of the show's original run, Judge was running on empty. "I actually wanted to stop a little sooner," Judge told the Los Angeles Times in 1997. "We've done over 200 episodes [since 1993]. After the second season, I thought, 'How are we gonna do this anymore?' I was completely burnt out. I got a second wind in season three, and again in season five. But I don't know, you do it as fast as you can, get it on the air as fast as you can, and there's never a break. I felt, like, why not retire before it gets too stale or whatever?"

17. Kanye West wanted to be on Beavis and Butt-head.

In contrast to the more innocent 1990s, Judge and his team had to get authorization from all of the parties involved in a music video to have it appear on Beavis and Butt-head when it returned in 2011. Kanye West wanted to have one of his videos featured on the show, but another credited songwriter on the undisclosed track declined immortality.

18. Beavis and Butt-head is coming back for today's generation.

In July 2020, The Hollywood Reporter announced that Beavis and Butt-head is coming back for two all-new seasons, this time to Comedy Central. Mike Judge will oversee the series yet again, but this time it will be geared toward a "whole new Gen Z world."

"We are thrilled to be working with Mike Judge and the great team at 3 Arts again as we double down on adult animation at Comedy Central," Chris McCarthy, president of ViacomCBS' entertainment and youth group, said. "Beavis and Butt-Head were a defining voice of a generation, and we can’t wait to watch as they navigate the treacherous waters of a world light-years from their own."
