14 ’70s TV Characters Who Got Under Everyone’s Skin

Television in the 1970s gave us some truly memorable characters, but not all of them were beloved.
Some characters had a special talent for getting on viewers’ nerves with their annoying habits, clueless behavior, or grating personalities.
Whether they were meant to be funny or just turned out that way, these characters made audiences groan every time they appeared on screen.
Here are fourteen ’70s TV characters who really knew how to push everyone’s buttons.
1. Cousin Oliver – The Brady Bunch

He showed up in the final season as Carol’s nephew, and fans immediately hated him.
The producers hoped a cute kid would boost ratings, but instead they created the infamous “Cousin Oliver Syndrome.”
His arrival signaled the show was running out of ideas.
Every scene with Oliver felt like watching someone try too hard to be adorable and witty.
Viewers wanted the original Brady family dynamics back, not some random kid taking up precious screen time.
The character became so infamous that TV critics still reference him today. “Cousin Oliver” is now shorthand for any desperate attempt to save a dying show.
Even decades later, he remains one of television’s most unwanted additions.
2. Nellie Oleson – Little House on the Prairie

With her blonde ringlets and smug smile, Nellie made life miserable for Laura Ingalls and everyone else in Walnut Grove.
She was the ultimate spoiled brat who loved flaunting her family’s wealth.
Her nasty comments and cruel pranks went way beyond normal childhood rivalry.
Viewers watched her bully Laura week after week with barely any consequences.
Mrs. Oleson usually defended her daughter’s terrible behavior, making things even worse.
The whole Oleson family seemed designed to make audiences want to throw things at their TV screens.
Alison Arngrim played the role so convincingly that some fans couldn’t separate her from the character.
She received actual hate mail from viewers who despised Nellie.
3. Frank Burns – M*A*S*H

Nobody combined incompetence and arrogance quite like Major Frank Burns.
He constantly brown-nosed his superiors while treating everyone else like garbage.
His surgical skills were questionable at best, yet he acted like a medical genius.
His affair with Hot Lips Houlihan created endless awkward moments.
Frank’s whiny voice and childish tantrums when things didn’t go his way drove both characters and viewers crazy.
He tattled on Hawkeye and BJ like a petulant schoolboy rather than a grown military officer.
When Larry Linville finally left the show, many fans actually celebrated.
Frank Burns represented everything wrong with authority figures – small-minded, hypocritical, and thoroughly irritating in every possible way.
4. Ted Baxter – The Mary Tyler Moore Show

Ted was the vain, dimwitted news anchor who somehow kept his job despite being completely clueless.
His inflated ego had no basis in reality, which made every conversation with him exhausting.
He constantly bragged about himself while missing obvious jokes and social cues completely.
The character worked because Ted Knight played him as genuinely oblivious rather than malicious.
Still, watching Ted take credit for others’ work or misunderstand simple concepts got old fast.
His vanity reached ridiculous levels, especially considering his actual lack of talent.
Ted’s stupidity provided lots of laughs, but you wouldn’t want him in your actual workplace.
His combination of arrogance and ignorance remains timeless.
5. Sue Ann Nivens – The Mary Tyler Moore Show

The “Happy Homemaker” had two faces – sweet as pie on camera, absolutely vicious off it.
Sue Ann smiled while delivering cutting insults disguised as compliments.
Her aggressive pursuit of any available man, especially Lou Grant, made everyone uncomfortable.
Betty White brilliantly portrayed this passive-aggressive nightmare who competed with Mary at every turn.
Sue Ann’s fake sweetness somehow made her nastier than outright villains.
She’d steal your boyfriend while offering you a recipe for chocolate chip cookies.
Her man-hungry behavior and backhanded comments created constant tension.
Sue Ann proved that the most dangerous people are those who smile while stabbing you in the back with impeccable manners.
6. Arnold Horshack – Welcome Back, Kotter

“Ooh!
Ooh!
Ooh!” – that annoying sound echoed through classrooms across America every week.
Arnold enthusiastically raised his hand for every question, whether he knew the answer or not.
His goofy laugh and desperate need for approval wore thin quickly.
While the other Sweathogs had their annoying moments, Horshack took it to another level.
His constant interruptions and attention-seeking behavior would drive any real teacher insane.
He tried so hard to be the teacher’s pet that he became everyone’s least favorite student.
Ron Palillo made Horshack lovably pathetic, but that didn’t stop viewers from wanting to stuff a sock in his mouth.
His eager-beaver routine got repetitive fast.
7. Mr. Roper – Three’s Company

Stanley Roper spent most of his time spying on his tenants and making inappropriate comments.
His obsession with Jack’s supposed homosexuality led to countless awkward moments.
Mr. Roper was nosy, cheap, and had zero respect for anyone’s privacy or personal boundaries.
He constantly barged into the apartment without knocking to check up on the roommates.
His relationship with his wife Helen consisted mainly of insults and complaints.
Watching him creep around trying to catch Jack in some made-up scandal got old really fast.
Norman Fell played him as perpetually grumpy and suspicious of everything.
Mr. Roper represented the worst kind of landlord – intrusive, judgmental, and thoroughly unpleasant to deal with regularly.
8. Ralph Furley – Three’s Company

When Mr. Roper left, the show replaced him with something arguably worse.
Ralph Furley dressed like a disco reject and thought he was God’s gift to women.
His tacky polyester outfits and gold chains were blinding, and his pickup lines were even more painful.
Don Knotts played Furley as a delusional Casanova who struck out constantly.
He interfered in the roommates’ lives just as much as Roper did, but with more desperation.
His attempts to be hip and cool made viewers cringe week after week.
At least Roper knew he was grumpy.
Furley genuinely believed he was smooth and attractive, which somehow made him even more annoying to watch stumble through life.
9. Larry Dallas – Three’s Company

Jack’s best friend Larry was a walking stereotype of sleazy ’70s bachelors.
He thought every woman wanted him and gave terrible advice about relationships.
His constant schemes to pick up women usually backfired, but he never learned his lesson.
Larry treated women like conquests and bragged about his supposed romantic successes.
He encouraged Jack to lie and cheat, acting like the worst possible influence.
His polyester suits and thick mustache matched his greasy personality perfectly.
Richard Kline made Larry just charming enough to be Jack’s friend, but most viewers saw through the act.
His shallow, manipulative approach to dating represented everything wrong with ’70s pickup culture.
10. Jan Brady – The Brady Bunch

“Marcia, Marcia, Marcia!” might be TV’s most famous whine.
Jan spent every episode complaining about living in her sister’s shadow.
While having a perfect older sister would be tough, Jan’s constant jealousy and self-pity became exhausting to watch.
She tried ridiculous schemes to get attention, from wearing a black wig to making up a fake boyfriend.
Her insecurity turned into manipulation more than once.
Instead of developing her own identity, Jan obsessed over what Marcia had that she didn’t.
Eve Plumb captured middle-child syndrome perfectly, but that didn’t make Jan less irritating.
Her endless complaints about being overlooked made viewers want to tell her to just get over it already.
11. Hot Lips Houlihan (Early Seasons) – M*A*S*H

Major Margaret Houlihan started out as a by-the-book nightmare who made everyone’s life harder.
Her affair with Frank Burns and rigid adherence to military rules created constant conflict.
She reported every minor infraction to Colonel Blake while ignoring real problems.
Early Margaret was hypocritical, uptight, and mean-spirited toward the nursing staff.
She kissed up to authority while treating subordinates terribly.
Her shrill voice when yelling at Hawkeye or Trapper became grating fast, especially since she was usually wrong.
Loretta Swit eventually transformed the character into someone more sympathetic.
But those early seasons featured a Hot Lips who earned her nickname for all the wrong reasons – she was impossible to work with.
12. Edith Bunker – All in the Family

Her high-pitched voice could shatter glass, and her endless rambling stories tested everyone’s patience.
Edith meant well, but her inability to understand sarcasm or get to the point drove Archie and viewers crazy.
She’d start telling a simple story and somehow end up discussing her cousin’s neighbor’s dog.
While some found her sweetness endearing, others wanted to fast-forward through her scenes.
Edith’s doormat behavior and refusal to stand up to Archie frustrated progressive viewers.
Her childlike innocence worked as a character trait but got tiresome over multiple episodes.
Jean Stapleton played Edith with genuine warmth, but that voice and those wandering conversations remained hard to sit through for many fans of the show.
13. Radar O’Reilly – M*A*S*H

Some viewers found Radar’s innocent farmboy act cloying and overdone.
His habit of finishing Colonel Blake’s sentences was supposed to be endearing but often came across as annoying.
The teddy bear and grape Nehi soda made him seem more like a child than a soldier.
Radar’s wholesome goodness felt unrealistic given the show’s setting in a war zone.
His naivety provided comic relief, but it also made serious scenes less believable.
How could someone be that pure and innocent while working in a mobile hospital during wartime?
Gary Burghoff played him earnestly, yet Radar’s constant wide-eyed shock at the real world wore thin.
His character worked better in small doses than as a regular presence.
14. Chrissy Snow – Three’s Company

The dumb blonde stereotype reached peak annoyance with Chrissy Snow.
Her complete inability to understand simple concepts or follow basic conversations wasn’t cute – it was painful.
She made Janet look like a genius by comparison, which wasn’t hard to do.
Chrissy’s tight clothes and giggly personality reduced her to pure eye candy.
Her stupidity went beyond funny into genuinely concerning territory.
How did she remember to breathe?
The writers relied too heavily on her confusion for cheap laughs rather than giving her actual personality.
Suzanne Somers played the role with commitment, but Chrissy represented everything wrong with how ’70s sitcoms treated female characters.
Her departure from the show honestly improved things for many viewers.
