Peanuts has multiple iconic sibling duos, like Sally and Charlie Brown or Snoopy and Spike. However, one of the most popular and hilarious sibling rivalries in Peanuts history is Lucy and Linus - mostly thanks to Lucy's hair-trigger temper and overall bossiness when it comes to her little brother. Lucy is a handful with just about anyone, but when it is family, she amps up her bossiness to eleven, much to Linus's misfortune.

Regardless, Linus does not always bow down to his big sister, fighting back even when Lucy is at her most imposing. Lucy is not the easiest person to stand up to, but Linus tries his best, even if it ends up being for naught a lot of the time anyway. From going overboard in critiquing his artwork to her constant nagging of her younger sibling, Lucy is the definitive bossy big sister.

10 "That's Not Art!"

November 27th, 1967

Lucy looks at Linus's drawing and automatically deems that it is not art because it is a terrible drawing and that her little brother has no talent whatsoever. Linus pays no mind to his overly critical big sister and continues to draw, annoying Lucy, who is not satisfied since no one listens to critics, including her little brother.

Lucy has made a habit of pointing out all the things she finds wrong with Linus's drawings, claiming that his work is never art - unless, of course, he adds the suggestions she insists on. Not only does she insist that his work is not art, but she then goes on to insist that his drawings are awful on top of it, adding insult to injury. Rarely are the roles reversed where Linus will critique Lucy's artwork, with him likely being too scared of his sister's wrath to give it a try.

9 "Then, Here We Go!"

April 24th, 1989

Sitting on the couch with her little brother, Lucy poses a question to Linus: "if someone close to you noticed that you had some faults, would you want them pointed out to you?" Linus, thinking that this is a hypothetical scenario, answers that he thinks he would want the flaws pointed out. Lucy instead takes this as a challenge and is ready to list off Linus' faults right then and there.

This strip is not the first time that Lucy volunteers to show someone their faults. She has told Linus his faults many times before, and Lucy has even gone through the trouble of making a slideshow of all Charlie Brown's faults separated by category, making him watch it. Lucy is never that open to hearing about any of her faults, showing that she does not live up to the old saying "if you can't take it, then don't dish it out."

8 "Does It?"

March 21st, 1963

When Linus gets the news that he did not make the honor roll for the month, he gets upset, knowing that his parents will not be happy since they want him to be the "smartest kid in the world." There's nothing like a lot of unnecessary pressure to motivate an elementary school student. Regardless, Lucy guilt-trips her little brother on their parents' behalf when she tells him how disappointed their mom and dad are with him after he did not make the honor roll.

Linus is level-headed about it all after the initial upset he felt, not beating himself up about not making the honor roll and knowing that it is not the end of the world. But Linus then questions if it actually could be the end of the world, asking his big sister just in case she knows something that he doesn't.

7 "Maybe I'll Have It Made into a Sport-Coat!"

June 23rd, 1958

Lucy yells at Linus about his blanket and how his attachment to it is so strong that he will be dragging it around for his entire life. Linus fights back, suggesting that he will not drag it around forever; instead, he may have it made into a sport-coat. Apparently, Linus is an early adopter of upcycling, even if it's with the intention of preserving his beloved blanket to have with him as an adult and of looking spiffy at the same time.

This Peanuts strip was adapted into the 1965 TV special, A Charlie Brown Christmas.

Linus's blanket has has many different uses and forms, so a sport-coat transformation is not exactly out of the question. However, if the blanket survives, Lucy will not withhold any of her wrath, already having no patience for Linus and his blanket, as this strip evidences.

6 "It Was Too Much Trouble..."

November 17th, 1964

Looking in Linus's drawer, Lucy finds a shirt that is brand-new and that he has never worn. She wonders why he has not worn it yet, since he has had it for a whole year completely untouched. Linus claims that the shirt was too much of a hassle to wear because he would have to take all the pins out. At the time of this strip's publication, new shirts had pins in them as a way to keep the shirt tidy and neat for packaging.

Consequently, Linus not bothering to wear the shirt because he does not want to deal with the pins shows that he can be a bit lazy, much to his sibling's annoyance. Never hesitating to bug Linus about anything, big or small, Lucy will get to the bottom of anything involving Linus if it bothers her even the least bit.

5 "I Just Like Grudge Matches"

May 14th, 1985

Out of nowhere, Lucy interrupts Linus's TV watching to start a grudge match with him. Linus does not have a grudge with his sister - not at the moment, anyway - so he questions what said grudge match would even be at. Lucy has no special preference; it could be about anything, because she just really wants a grudge match.

Considering that Lucy has an issue with just about everyone at one point or another, if she really wants a grudge match, she probably won't be hard-pressed to find someone who is ready and willing.

The formal meaning of a grudge match is when there is a competition between opponents who have a personal animosity towards each other. Considering that Lucy has an issue with just about everyone at one point or another, if she really wants a grudge match, she probably won't be hard-pressed to find someone who is ready and willing - unlike Linus, who just wants to watch TV. Most kids would not decide to have a grudge match just for something to do, but most kids are not as naturally aggressive and brash as Lucy.

4 "I'm Warning You, Linus!"

March 19th, 1965

Convinced that Linus's blanket hates her, Lucy gets some proof for her outlandish claim when the blanket attacks her out of the blue. With how many attacks, verbal and physical, that Lucy has launched against the blanket, it really is only natural that the blanket does not have any fond feelings towards Lucy.

Lucy yells at Linus with one last warning to keep his blanket away from her or else she will destroy it; she even threatens to throw it in a trash burner. The blanket moves towards her in a hand shape, scaring her, but Linus explains that the blanket just wants to make up by shaking hands. Offended at even the idea of shaking hands with a blanket, Lucy flat out refuses, yelling at Linus and the blanket. Somehow she wonders why the blanket hates her.

3 "Rats Have to Have a Place to Live, Too, You Know!"

November 28th, 1966

As Lucy rushes Linus out the door to avoid being late to school, she hounds him about getting ready, like brushing his teeth. She then goes a step further when she tells him to comb his hair, telling Linus that his hair looks like a rat's nest, which is a very blunt insult to receive in the morning. While Linus may not love Lucy's bossing around - and especially the way she does so in this strip - he gives it right back to her, reasoning that rats need somewhere to live, too.

Whether it be his uncombed hair or anywhere else, Linus is fine with having a rat's nest on his head... literally, apparently. As the oldest of her siblings, Lucy is destined to be bossy, a role she relishes with glee and without hesitation, which is on display in this comic strip.

2 "Do You Understand?"

February 12th, 1963

In a screaming match about Linus understanding Lucy, he insists that she does not always have to yell at him. His retort surprisingly stops Lucy's yelling in its tracks and makes her rethink things, wondering if he could be right. But at the same time, she feels like if she were to speak to him in an indoor voice, he would never listen.

As a result, she reasons that talking to Linus necessitates yelling, otherwise it completely goes over his head, and he does not listen. Communication between siblings can be infuriating, especially when one does not listen and one is overly aggressive, which just so happens to be the dynamic between Linus and Lucy. As much as she likes to act like she would talk quietly if she could, readers know that Lucy loves to be loud and bossy, and would be the exact same even in a world where Linus listens.

1 "That's Art!"

October 13th, 1968

Linus describes his drawing, but even as he explains what he wants to add, Lucy reasons that it will not make his drawing art. Instead, she reasons that Linus needs to add a laundry list of things for his drawing to be considered art, like a waterfall and red streaks in the sky. Linus listens to Lucy's words of advice, and when she sees his new work, she explains how his new drawing is now finally art, exclaiming it at him.

This comic strip is the only Sunday Peanuts strip in 1968 that did not have the tagline "Featuring Good ol' Charlie Brown."

Proud of improving Linus's work, Lucy says to herself that a layperson is needed to set artists straight. In this Peanuts strip, Lucy sees it as her own personal job to shape Linus's drawings to fit her definition and view of art, even if she is basically just telling Linus what to put in his work, whether he wants to or not.
