- Baby-Doll Baby: Homer takes a quiz that indicates he's going to die and goes a little crazy. At the plant he's found "nursing" a doll (missing an arm). His theory is that if he's a mother he can't die.
- Babysitting Episode:
- In what was originally the very first episode, but was delayed to the first season finale, concerns Homer & Marge going out for the evening while the kids are sat by what turns out to be "the Babysitting Bandit," who gets a babysitting job and then ties up the kids and steals everything from the house.
- In another episode, 8-year-old Lisa offers her services as a babysitter, but the only ones who will take her up on it are Homer & Marge, who have her watch Bart and Maggie. Bart does a lot of stupid things mostly for the sake of being contrarian, which eventually lends him in the hospital (she even has to drive him there in a wheelbarrow because he prank-called them earlier), but she still gets work afterwards.
- While healing from a work injury, Homer starts a Daddy Day Care-type in-home babysitting service.
- Back Blocking: In the episode "Bart the Murderer". Fat Tony fills the screen as he and his boys corner Principal Skinner in his office and Skinner asks how they got past the hall monitor.
- Back from the Dead: Dr. Monroe (though now he's gone again), Dr. Nick, and Poochie (even though "The Itchy & Scratchy & Poochie Show" established that Krusty went through the trouble in getting a legal document stating that Poochie, by law, is not allowed back on the show).
- Backwards-Firing Gun: Mr. Burns moves the power plant to India. When one of Moe's patrons comments that the bar is being powered by imported electricity, Moe sees no problem and points out other imported stuff. When he's asked if he has anything made in America, he shows his shotgun and tries to shoot, causing it to backfire.
- Badass Family: It's a bit of a Running Gag that Maggie Simpson is the most Badass member of the family.
- Strangely, Homer shows some elements of this, especially in the movie. In the main series, he's often got involved in car chases that required him to kick someone's ass.
- He is also handy with a chain and cement block (which he calls "The Defender"), as well as being able to wield a motorcycle. Marge has thrill issues. Bart can hit a target with his slingshot at what is practically sniper range, and was able to perfectly wield a grenade launcher on his first use, even managing to hit Skinner's car at Springfield Elementary from his new military school (Springfield wasn't visible in the background). Really, all the characters have occasional flashes of this. With the possible exception of Lisa.
- Lisa has her moments, most notably with the episode "Lisa on Ice".
- There's also the time that Lisa one-hit KO'd Bart in a MMA ring.
- She also connects a gloriously-animated punch on Bart in the movie.
- Lampshaded by Marge of all people in an early episode, when Homer worries about his parenting.
Marge: The way I see it, if you raise 3 kids that can knock out and hog-tie a perfect stranger, then you must be doing something right!
- Badass Adorable: Again, Maggie Simpson. She shot Mr. Burns (though that was said to be an accident, as Burns' gun fell from his holster, and he didn't have the safety on). Oh, and she also shot the mobsters who were threatening to murder Homer. Homer didn't know she did the latter, but when he heard the gunshots and saw those mobsters fall to the ground, he said "I must have a guardian angel with a rifle." This might actually have put her into a borderline Enfante Terrible Anti-Hero category if not for how obvious it was that her targets deserved it. In a later episode when Homer was imprisoned in a basement of a tow truck driver, Maggie saved him by riding on Santa's Little Helper to the place, and attaching the guy's towhook to the cellar window bars.
- Maggie also led a Great Escape-esque mission through a daycare in order to secure pacifiers for all of the babies there.
- Badass Grandpa: Abe Simpson is usually shown to be a rambling, partially senile old man who crushed his son's self-esteem and abused him the same way Homer abuses Bart. However, "Raging Abe Simpson and His Grumbling Grandson in, 'Curse of the Flying Hellfish'" revealed that he was a competent military officer and he kicked Mr. Burns' ass for trying to steal the stolen art tontine and for nearly drowning Bart.
- Badass Boast: In "Missionary:Impossible" Bart pledges $10,000 to the Fox network and a hilarious caricature of Rupert Murdoch shouts "You've saved our network!" to which Bart replies, looking at the camera, "Wouldn't be the first time". This is of course Lampshade Hanging as the popularity of the Simpsons has ensured the ongoing success of Fox despite their long list of failed, forgettable live action shows. This came right after Betty White discussed the importance of saving 'lowbrow and crude' shows on the network and the Family Guy logo showed.
- Bad Bad Acting: In the episode "Burns's Heir", Mr. Burns hires actors to portray the rest of the Simpson family in order to persuade Bart that they don't love him. They do this in the most wooden way imaginable (even though the actors picked to play the family only gave a crummy performance because of how bad the script wasnote .
Fake Homer: *Monotone* I do not miss Bart at all.
Fake Marge: *Also monotone* I am glad he's gone.
Fake Lisa: *Also monotone* As am I.
Fake Homer: *Drops his sandwich* B'oh! (and later, "Duh-Oh")
Bart: It's probably my imagination, but something about them just didn't feel right.
- Another example of bad acting occurs in "D'oh-in' in the Wind": Homer, Lenny, and Carl acting in Mr. Burns's Power Plant commercial.
Homer: Well, there were script problems from day one.
Bart: Didn't seem like anybody even read the script.
Homer: That was the problem.
- Bad Future: The year 1,000,000 A.D. at the end of "Rosebud": The Earth is a barren place, the only human alive is Homer (who has been cloned and used as slave labor to apes, who have taken over the world), and Mr. Burns and Smithers are still alive, albeit as cyborgs (with Smithers as a cyborg dog).
- "The Good, The Sad, and the Drugly" mentioned this trope in the subplot where Lisa researches what life will be like in 50 years, and becomes paranoid and depressed (to the point that she has to be put on anti-depressants) over predictions of Springfield becoming a barren wasteland.
- Bad Job, Worse Uniform: The teenagers who work at Krusty Burger or Phineas Q. Butterfat's ice cream parlor.
- Also Barney, when he was hired to pass out flyers in front of a baby furniture store called Lullabuy$, clad only in a diaper and bonnet (it was the dead of winter at the time).
Barney (after his diaper flies away in the breeze and he runs naked down the street): Hi, Ma!
- Bad Present: In "The Springfield Files", a man wakes up from a 23-year coma and asks if Sonny and Cher still have "that stupid variety show". Kent Brockman replies that Cher won an Oscar and Sonny (before he died in the mid-to-late 1990s) is a Congressman. The man says, "Good night!" and dies.
- Lampshaded in "Bart to the Future":
Homer: What a bleak and horrible future we live in!
Bart: Don't you mean, "present"?
Homer: Right, right, present.
- Bags of Letters: When Homer files a lawsuit against a seafood restaurant whose definition of "all you can eat" differed from his, the defendant asked for a display of how much Homer ate that night. At that point parodying the film Miracle on 34th Street, a huge convoy of people carrying large sacks enter the court, but it turns out that they just contain letters for an adjacent courtroom (People of Springfield vs Santa Claus, IIRC).
- Bait and Switch: The absolute master of this form of humor, and arguably one of the first comedies to use it on a regular basis.
- Banging Pots and Pans: In a Flash Back to when Bart was two and Marge was pregnant with Lisa, we see Bart with a pot on his head, banging another pot.
Bart: I am so great! I am so great! Everybody loves me, I am so great!
Marge: Honey, honey, honey, honey, honey. Could you please be quiet?
Bart: Quiet! Quiet! Quiet! Quiet! Quiet! Quie —-
Marge: Bart, get out!
- Bathtub Scene:
- Edna gets one in "Bart the Lover" when she reads "Woodrow"'s love letter.
- Selma gets one in "Black Widower" (also reading a love letter she got from a man).
- Homer gets one in "A Milhouse Divided" (when Bart breaks a chair over Homer's head to see if he can withstand the pain from the hit).
- Homer and Marge try to spice up their romantic life by having a bath together in "Grampa vs. Sexual Inadequacy" (which fails, as Homer is too fat to fit in the tub, the water kills the light on all the candles, and the two have to call the kids in to get out).
- Marge gets one in "Homer Alone" (the scene where she watches Thelma & Louise while eating a hot fudge sundae with a chocolate chip cheesecake and drinking tequila)
- Batman in My Basement: In "The Fool Monty", Bart finds a brain-damaged Mr. Burns in the woods and takes him home, attempting to hide him in his bedroom.
- Bat Scare:
- In "The Seemingly Never-ending Story", the Simpsons get stuck in caves. The obligatory flock of bats appears, and everybody is scared but baby Maggie; being the Badass Adorable that she is, she enthusiastically greets the bats with waving.
- Bats fly out of the card catalog drawers at the public library.
- Bat Signal: Accidental example when Homer stands in front of a lighthouse, causing his silhouette to be projected onto the clouds.
Bart: Hey look! Is that Dad?
- Bawdy Song and Take Our Word for It: On "Thirty Minutes Over Tokyo," The Simpsons are seated at a restaurant table shaped like Massachusetts:
Homer: Hey, you know, I once knew a man from Nantucket.
Homer: Let's just say the stories about him are greatly exaggerated.
- Another time, Homer referred to the poem in a very Purple Prose manner, still stopping before he got to "the good part".
- Beach Bury: Ned is buried like this and Homer parks his car on top of him.
Flanders: Homer, is that my muffler?
- Beat Still, My Heart: On "New Kid on the Block," after Bart is crushed to hear that Laura has a boyfriend, he imagines Laura ripping his heart out and kicking it into a garbage can, complete with blood trail. In "Goo Goo Gai Pan," a monk rips Homer's heart out and puts it back in, without Homer feeling any pain. Also, "Homer's Triple Bypass" had an inside look on Homer's heart reacting to Mr. Burns yelling at him.
- The Beard: Apu pretending to be married to Marge so he won't have to go through with an arranged marriage in "The Two Nahasapeemapetilons".
- Beard of Sorrow: Homer has grown one before when separated from Marge.
- Bear Trap Bed: Seen in "Pokey Mom".
- Be Careful What You Wish For: Run through the gamut in the first segment of "Treehouse of Horror II," which itself is based on "The Monkey's Paw," one of this particular trope's codifiers. The segment revolves around a monkey's hand that grants four wishes.
- Averted with Maggie, who uses the hand's first wish for a new pacifier.
- Played straight with both Bart and Lisa, who use the second and third wish for "the Simpsons to become rich and famous" and world peace, respectively. The town gets sick of the family's image appearing everywhere, leading to the Simpsons being ostracized, and Lisa's world-peace wish leads to a destruction of all the planet's weapons, which allows Kang and Kodos to take over the globe and enslave its people.
- Played for laughs with the last wish: Homer, determined to "make a wish that can't backfire," decides to request a turkey sandwich. He's even smart enough to make various codicils for the wish, including "no zombie turkeys," not being transformed into a turkey, and not wanting "any other weird surprises." And yet Homer still winds up on the losing end, as the sandwich is a disappointment (the turkey is a little dry!) and he ends up throwing it away.
- Finally, it's invoked and averted again in the ending. As Homer goes to throw out the hand, he instead gives it to Flanders, hoping to see Ned suffer because of this trope. Ned uses his first two wishes to get rid of the aliens and "spruce up the ol' homestead," transforming his house into a castle, with no repercussions, much to Homer's chagrin.
- Bedsheet Ladder: Used by the couch to escape from the Taj Mahal in a Couch Gag.
- Before I Change My Mind: In "Simpson and Delilah", Mr. Burns almost fires Homer for making a "mockery" of the morning meeting (merely due to being bald), but decides not to because he can empathize with Homer's baldness. He lets him return to his Sector 7G job, but states "Now get outta here before I reconsider."
- Befriending the Enemy: Bart's tried to befriend his bully and antagonist. Nelson Mutz, in some episodes. The first time to become popular, which resulted in Bart being bullied even harder when Nelson found out he was being manipulated. In later seasons however, Bart and Nelson have become friends over time, and Bart even calls him “his other best friend” in one episode.
- Belly Buttonless: In one episode, Homer's life is invaded by an army of clones of himself. The clones, predictably enough, lack belly buttons.
- Bestiality Is Depraved:
- A lot of people have made fun of Bill Clinton's promiscuity, but probably no-one else has gone quite as far as "Hell, I done it with pigs. Real, no-foolin' pigs!" from "Homer to the Max".
- It's heavily implied that Troy McClure's career went down the drain at least in part due to the fact that he has a sexual fetish for fish. Naturally, this is all he is remembered for, his many B-movie roles notwithstanding.
Louie: Troy McClure!? You said he was dead!
Fat Tony: No, what I said is that he sleeps with the fishes! You see...
Louie: Uh, Tony, please, no. I just ate a whole plate of dingamagoo.
- Be Yourself: Tacked on at the end of "Homer to the Max" to explain why Homer changed his name back from Max Power to Homer Simpson. Also the Aesop for the episode "Lisa Goes Gaga".
- The B Grade: Lisa freaks out in "Kamp Krusty" when she's given a "B" in "Conduct". She also stresses when she gets an "A-" in "Bart vs. Lisa vs. The Third Grade", especially since Bart scored a solid "A".
- Bigger Bad: Bart's Kindergarten Teacher from Lisa's Sax and Mr. Burns' grandfather qualify as such.
- Big Damn Movie: The Simpsons Movie is about rescuing Springfield from ecological destruction.
- Big Eater: Homer, bordering on Extreme Omnivore
- Bigger Than Jesus: In the episode "Homer's Barbershop Quartet," Homer's titular band with a history that very much resembles that of The Beatles is alleged to have frequently boasted to be "bigger than Jesus" and even titled their sophomore album as such with a cover that shows the band Walking On Water in the Abbey Road Crossing pose.
- A later episode referenced The Beatles controversy when it turns out that Ned Flanders has a huge collection of Beatles memorabilia. Why? Because they were bigger than Jesus!
- Bilingual Bonus: Done frequently with Bumblebee Man sketches; whilst they're always non-sequiturs, what is gibberish to the layman becomes funny gibberish to the bilingual:
Original "¿Dónde Está Justice?" transcript:
Plaintiff: ¡El Ford Escort que me vendío es un limón!
Defendant: No no no no no. No es un limón. Es un carro fuerte.
Judge: Hmm, limón... fuerte... limón... fuerte... limón... ay-yi-yi-yi-yi, ¡mi estómago!
Plaintiff: The Ford Escort he sold me is a lemon!
Defendant: No no no no no. It's not a lemon. It's a strong car.
Judge: Hmm, lemon... strong... lemon... strong... lemon... ay-yi-yi-yi-yi my stomach!
- Big Little Man: Moe has a date set up with a dwarf girlfriend, but he thinks she's bigger since her online photo was of her looking tall in front of the Empire State Building (actually the one in Lego Land).
- Big "NEVER!"
- Particularly in "Two Bad Neighbors":
Homer: For the last time, Bush, apologize for spanking my boy!
Bush: Never! You make him apologize for destroying my memoirs.
Homer: (to Bart) You didn't tell me you destroyed his memoirs... (to Bush) Never!
- In the school play about the founding of America in "I Love Lisa":
Lisa (as Martha Washington): Wouldn't it just be easier to give in to the British?
Ralph (as George Washington): NEVER! (audience applauds)
- Big "NO!" and Slow No: Many, many instances in several episodes:
- "Bart's Comet": Skinner shouts this three times: Once, when he hears the other end of a phone conversation that congratulates Bart for discovering a comet; twice, when he accidentaly releases the "Hi! I'm Big-Butt Skinner" balloon and it floats away; and third when a paperboy throws a paper at Skinner's feet with the headline: "Prez Sez: School is for losers."
- "Duffless": Shouted in slow motion when Lisa's giant tomato is thrown at Skinner's butt.
- "Homer: Bad Man": Shouted by Godfrey Jones when Homer comes towards him during the interview.
- "King-Size Homer": Homer shouts this when he's forced to join the calisthenics class.
- "On a Clear Day I Can't See My Sister": Played with, as Grampa is actually shouting "Gnomes!"
- "She Used To Be My Girl": Marge shouts this after a daydream.
- "Bart's Dog Gets an F": Homer shouts this after SLH eats apart his brand new ASSASSINS sneakers. Only it morphs into a howl when Homer says it at the same time.
- The German dub turns all of Homer's D'ohs into Little Nos (Nein!)
- "Elementary School Musical": Lisa says this after spending a week in an arts camp, which Lisa explains to Marge via digital camera.
- "Marge's Son Poisoning": Marge shouts this when she envisions herself and Bart as older singing karaoke together.
- "Homer and Lisa Exchange Cross Words":
Lisa: "My name is now Lisa Bouvier"
Nelson: Hi, Mr. S. Lisa B.
Janey: "Want to buy some band candy?"
- "I Love Lisa": Said by Lisa in a live audience at the Krusty Anniversary special:
Krusty: And is this your girlfriend, Ralph?
Ralph:Yes, I love Lisa Simpson, and when I grow up, i'm going to marry her.
Lisa: Noooooooooooooo!!! Now you listen to me. I don't like you. I never liked you. And the only reason I gave you that stupid valentine is that nobody else would!
- "And Maggie Makes Three": Happens the moment Homer finally finds out about Marge's pregnancy:
Maude: By the way, congratulations on your new job, Homer.
Homer: New job? ...Marge is pregnant?! [pulls hair out] Noooooo! [runs up stairs screaming, slams bedroom door]
Ned: I just attacked all my friends and neighbors just for trying to help me. I'd like to commit myself.
Nurse: Very well. Shall I show you to your room, or would you prefer to be dragged off kicking and screaming?
Ned: Ooh, kicking and screaming, please.
Nurse: As you wish.
[two men in white grab hold of him and drag him away]
- In "Home Sweet Homediddly-Dum-Doodily", when Homer stops Ned from baptizing Bart.
- In "Homer Alone", when Marge has a nervous breakdown after Maggie spills milk all over the car.
- In the first minute of "The Bart Wants What It Wants", one of the Olympic Administrators do this when they survive the plane crash, but realize the Olympic Flame is not lit anymore. Oh, and a 'Big No' it is.
- A Birthday, Not a Break:
Homer: I can't believe it. I'm being mocked. By my own children. On my birthday!
Bart: It's your birthday?
Homer: Yes! Remember, it's the same day as the dog's.
Lisa: Santa's Little Helper, it's your birthday? Ooh! We've gotta get you a present.
- Birthday Episode:
- In one episode Homer gives Marge a bowling ball for her birthday - despite the fact that she doesn't bowl. He even got it inscribed with his name, on the assumption that she'd give it to him to use. She takes up bowling just to spite him, claiming that Homer is the name of her ball.
- In the Michael Jackson episode, Lisa turns 8. Nobody pays attention. In the end, Michael & Bart write a song for her.
Lisa it's your birthday
Happy birthday Lisa!
- Biting-the-Hand Humor: They mocked Fox (and the many Dueling Shows The Simpsons has had over the years, including Family Guy) countless times.
- Black and Gray Morality
- Black Belt in Origami: In one episode, Homer tries to bluff his way into getting a veteran's discount by pretending to have served in Vietnam. He shouts several Asian words (up to and including Margaret Cho) as reference to specific battles he was supposedly involved with.
- Black Comedy: Progressively more so over the years. Most fans blame "Homer's Enemy" as the episode that brought about the use of Dead Baby Comedy on a frequent basis.
- "The Boys Of Bummer" from season 18 is an oft-cited example. While it did have moments of comic relief (i.e., the subplot of Homer being a mattress tester and the end where Marge tells Homer that ghost sex isn't the same as real sex), the main plot of Bart losing the big Little League game and becoming a town pariah (to the point that he goes insane and attempts suicide) just crossed the line.
- Black Comedy Burst: The examples listed under Darker and Edgier. "Homer's Enemy," in particular, is among the series' darkest episodes.
- Bland-Name Product:
- Malibu Stacy, obviously based on Malibu Barbie).
- One episode featured Red Umbrella Insurance, a takeoff of the Travelers Insurance Company logo.
- The Mapple MyPod.
- The Fjord Fjiesta from "The Saga of Carl".
- Blatant Lies: Played with on a couple occasions:
- In "Homer vs. the 18th Amendment", when Homer is questioned by Marge about where he's going (that is, to go to the bowling alley to roll alcohol in bowling balls to Moe's), Homer replies with, "I'm not gonna lie to you, Marge...... so long!"
- In "Milhouse Doesn't Live Here Anymore", Marge questions where Homer's getting all the extra money. Homer replies that he's not going to lie to her... only to not say another word and continue reading the paper.
- In "Lisa's Sax", Homer flashes back to having said to Barney as a kid "Let's Never Drink Again!" Then in the present day he says, holding a beer, "And we never did!" as he proceeds to take a sip.
- Blazing Inferno Hellfire Sauce: The Merciless Pepper of Quetzalacatenango, also known as the Guatemalan Insanity Pepper. Homer has to lacquer his mouth and esophagus in order to eat one.
- Bleep Dammit: At a yard sale in "Two Bad Neighbors", the Simpsons sell a T-shirt with "Ayatollah A*saholla" written on it, with one of the S's in the second word always censored by Marge's hand, a fold, etc.
- Blinding Camera Flash:
- Used as a weapon against crazed robot Itchys and Scratchys at Itchy And Scratchy Land. Flashing them causes their brains to go haywire.
- Also in "Monty Can't Buy Me Love", after the Loch Ness Monster is put on display, Mr. Burns falls around from the camera flashes in a spoof of "King Kong".
- Blipvert: GABBO! GABBO!! GABBO!!!
- Blunt "Yes": Nelson uses this twice in a row during "22 Short Films About Springfield," when confronted by someone he pointed and laughed at.
Very Tall Man: Do you find something comical about my appearance when I'm driving my automobile?
Nelson : ... yeah.
Very Tall Man:: Everyone needs to drive a vehicle, even the very tall. This was the largest auto that I could afford. Am I therefore to be made the subject of fun?
Nelson: ... I guess so.
- Blond Guys Are Evil: In an episode where the Simpsons play up the Dumb Blonde jokes, Lisa is offended by them and asks why Bart finds them funny, cue lampshade hanging by Bart, "Only blonde girls are dumb, the boys are evil!" Note that Bart and Lisa are themselves blonde. (Though Bart is actually a redhead; he purposefully sunbleaches his hair to avoid being called Rusty.)
- When Milhouse moved to Capitol City in one episode, he started hanging out with "The Wrong Crowd", was acting out even before he moved, and dyed his hair blond.
- Bold Explorer: "Margical History Tour" features Lenny and Carl as Lewis and Clark, exploring the American Northwest, and Lisa as Sacagawea, the native woman who helped them—or, in this case, tried to help them, but gets frustrated by their stupidity.
- Bold Inflation: Kang and Kodos.
- Bond One-Liner: McBain has quite a few of these: "Ice to see you." after breaking out of an ice sculpture and shooting up the place; "Meeting adjourned" after shooting up a villain board meeting.
- Principal Skinner in "Lisa the Beauty Queen": "Copyright expired."
- Bond Villain Stupidity: In "Cape Feare", Bart is successfully able to stall Sideshow Bob from killing him by saying he has such a beautiful voice and asking him to sing the entire score of the H.M.S. Pinafore.
- Later, in "Sideshow Bob's Last Gleaming", this is both averted and played straight:
Bart: So, Krusty double crossed you. But your basic plan was pure genius. Where do you get your ideas?
Sideshow Bob: Oh please. Let's not embarrass us both with that hoary old "stall the villain with flattery" scheme.
Bart: I...should have known you were too smart to fall for that.
Sideshow Bob: Really? What type of smart? Book smart? Because there are a lot of people who are book smart but it takes a special type of genius to... (Chief Wiggum tells him to come out with his hands up)
- Book Dumb: Most of Springfield qualifies.
- Boomerang Bigot: Played for laughs by Willie.
Groundskeeper Willie: "Damn Scots! They ruined Scotland!"
- Boot Camp Episode: "The Secret War of Lisa Simpson": Bart is sent to Military School for doing mischief; Lisa joins so she can attend the camp's superior school.
- Borrowed Catchphrase: In "Summer of 4'2''", Lisa says "Ay caramba!" and "Don't have a cow, man!"
- In "Natural Born Kissers", Moe says "Won't somebody please think of the children?!", which is usually said by Helen Lovejoy.
- Bart, Lisa, Marge, Grampa, and Mr. Burns have all said Do'h at one point. Though Mr. Burns may be an aversion because he was in a mental state where Homer Simpson was literally all he could think about.
- One episode in which a public speaker insisted Springfield let loose and release their rebellious inner child. (In other words, act like Bart) Principal Skinner later attacks Bart with a slingshot "Eat my shorts young man!"
- Bottomless Magazines: Just about any time gun usage is shown, usually per Rule of Funny.
- In "The Secret War of Lisa Simpson", Lisa fires an M-16 wildly for almost 10 seconds ("Help! It's stuck on auto-fire!").
- In "The Simpsons Spin-Off Showcase" and many other episodes where Chief Wiggum uses his gun, he fires well over six times despite of it being a revolver. (He's also a terrible shot.)
- Box-and-Stick Trap: Homer tries to lure Bart with a bottle of Focusin pills. The string tied to his finger went all the way into Moe's Tavern while he waited.
- The Boxing Episode: "The Homer They Fall"
- A Boy, a Girl, and a Baby Family
- Boy Band: Bart, Milhouse, Nelson, and Ralph form The Party Posse in "The New Kids On The Blecch," which is being used as a recruitment tool for the US Navy.
- Braces of Orthodontic Overkill: The Trope formerly known as "Lisa Needs Braces".
- Brain Drain: One company attempted this, first unsuccessfully on Smithers, then successfully on Homer. It was successful for them for a brief while — Homer's ideas worked for them.
- Brake Angrily: Ned in "Viva Ned Flanders".
- Brand Names Are Better: One of the running jokes in the show is how The Simpsons can't afford the brand name products and have to get generic, obscure brands instead.
- Brandishment Bluff: Happens during "The Seemingly Never-Ending Story", as Moe, Mr. Burns and Rich Texan are facing off:
Rich Texan: (taking the gold from Marge) I'll take that gold...
Mr. Burns: No so fast, Shady Bird Johnson!
(Burns steps out from behind a stalagtite)
Burns: I'll take that gold...
Moe Szyslak: (enters from the shadows, holding a baseball bat) Yeah, you'll take it, and then you'll give it to me if you know what's good for ya.
(Burns and Rich Texan aim their guns at Moe)
Moe: You guys have guns?!
Well, so do I! (steps back into shadows, making gun-cocking noises
) Heh? Heh?
- Brats with Slingshots: Bart Simpson in the early episodes and on early 1990s merchandise.
- Brawn Hilda: Bart's impression of an East German woman consists of a fake moustache and saying "Kiss me or I crush you!" in a deep voice.
- Bread, Eggs, Breaded Eggs
Mr Burns: I suggest you leave immediately.
- From "Itchy & Scrathy The Movie" when Homer and Marge leave for a parent-teacher conference:
Marge: So long, kids. We'll bring back dinner.
Lisa: What are we having?
Homer: Well, that depends on how kids have been. If you've been good: pizza. If you've been bad... Let's see, uh... Poison.
Lisa: What if one of us has been good and one of us has been bad?
Bart: Poisoned pizza.
Homer: Oh, no! I'm not making two stops!
- In "The Wettest Stories Ever Told":
Ned: Horseplay? Rough-housing? Horse-housing?!
- Breaking the Fourth Wall: Played with, after Mr. Burns is shot. Dr. Hibbert says "I couldn't possibly solve this mystery. Can YOU?" points and stares directly at the audience. Then the screen pans over showing he was actually pointing at Chief Wiggum. Wiggum: "Sure, I mean of course I can, that's my job right?"
- Break the Cutie: Subverted in Dog Of Death. When Burns gets a hold of Bart's friendly, gentle pet dog, he does to the dog what was done to Alex in A Clockwork Orange to, as Burns himself put it, turn the dog into "a vicious, soulless killer." However, when Burns sends said dog after Bart, the dog's memories of good times with Bart prompt him to lick Bart's face instead of attacking him. When the other dogs come after Bart, said pet dog growls at the other dogs and scares them off, only to proceed to lick Bart's face AGAIN. Burns' attempt at breaking the dog's spirit yields, if any change in the dog at all, a result of the dog taking a level in badass while no longer being on Burns' side in the long run.
- Break-Up Bonfire: When Milhouse's parents get divorced, Luann carefully boxes up all of Kurt's possessions and then sets fire to the box.
- Bribe Backfire
Wiggum: I hope you're not suggesting that I would take that necklace as a bribe. Think again, dirtbag, cause I can swipe it later from the evidence locker.
Wiggum: (As a reaction, when Bart tries to bribe him with precious wedding day dishes) What does it say on my badge? (badge says: Cash Bribes Only)
- Subverted in "Bart Carny": Wiggum is actually the one who initiates the bribe idea, but Homer is so clueless that he doesn't realize Wiggum is asking for a bribe. Wiggum shuts down Homer's carny game as a result of his failure to bribe Wiggum to keep it open.
- Brick Joke: During "24 Minutes", Bart makes a phone call that accidentally gets crossed with that of Jack Bauer, so he leaves him a prank call. At the end of the episode, Bauer arrives to arrest Bart for the call.
- We get a triple-whammy in "Hello Gutter, Hello Fadder". In the opening, Moleman is seen being hassled by a pushy New Yorker, and is seen as defenseless. When he reappears later in the episode, he is revealed to be the king of the Mole People, and about to use an earthquake machine. His CMOA and Pre Ass Kicking One Liner, "No One Escapes From The Fortress Of The Mole People", is immediately dashed, as the bungie cord both Homer and Otto were on rebounds and sends them back to the surface, to which Moleman dejectedly says "Well, except for that."
- In "Alone Again, Natura-Diddly", Homer presents a dating video he made for Ned, warning him, "The audio needs some tweaking and there's some footage of Maggie being born that I couldn't get rid of." They watch the tape, and at the end the video abruptly cuts to Marge in labor with Maggie, to Ned's disgust.
- Season 1's Homer's Odyssey has Mrs. Krabappel warning the children before a field trip not to stick their arms out of the bus' windows and mentions a story about a boy who lost his arm this way. Two episodes later, in Bart the General, Grandpa Simpson introduces Bart to Herman, an one-armed military antiques dealer. How did he lose his arm, you ask? By sticking it out of a moving bus during a field trip.
- Brilliant but Lazy: Bart in "Bart Gets an F" (especially where Bart cries over failing his test, cites a failed battle fought by George Washington, and ends up passing), and "Lisa the Simpson" (which revealed that he was smart as a kid, but became dumb due to the Simpson gene — though "Lisa's Sax" revealed that Bart became a bad student because his kindergarten teacher hated him and he had a bad first day of school).
- British Brevity: Parodied with the Show Within a Show Do Shut Up from the episode "Missionary: Impossible". The PBS hosts describe it as Britain's longest-running series, then say they'll be showing "all seven episodes".
- British Rockstar
- British Royal Guards: The episode "The Regina Monologues" sees the family vacation in London, where Homer crashes their car through the front gate at Buckingham Palace and into the Queen's carriage. Royal guards beat Homer senselessly but stop half-way through to observe the Changing of the Guard. Homer's beating continues at the hands of the next group of guards on duty.
- In "Bart Vs. Australia," Homer mistakes a US Marine posted outside the American Embassy for one of these guards. The Marine punches Homer in the face after he starts making funny faces at him and curtly explains that he is not a British Royal Guard.
Homer: Hey! Are you like one of those English guards who can't laugh or smile or anything? [makes noises and faces at him][gets punched in the face] Ow!
Marine: No, Sir! US Marine Corps, Sir!
- And yet another episode has Homer mistake Shaolin Monks as the British guards. He's met with similar results.
- Broken Glass Penalty: With a remote-control plane instead of a ball. Although it was technically Nelson and Milhouse that crashed it, Bart goes to get it and gets caught, setting off the episode's A plot of Bart working in a burlesque house.
- Broken Record:
- Young Bart: "Can't sleep. Clown will eat me."
- Lenny Leonard: "Dental plan."
Marge: "Lisa needs braces."
- Bart and Lisa: "Can we have a pool, Dad? Can we have a pool, Dad? Can we have a pool, Dad? Can we have a pool, Dad? Can we have a pool, Dad?"
- Bart and Lisa: "Will you take us to Mt. Splashmore?"
- Ned Flanders: "We're done-diddly-doodily, done-diddly-doodily, done-diddly-doodily, done-diddly-doodily—" (SLAP!)
- Bart and Lisa: "Are we there yet?"
- Homer and Apu: "Are we in India Yet?" "No." "Are we in India Yet?" "No." "Are we in India Yet?" "No." "Are we in India Yet?" "No." "Are we in India Yet?" "No." "Are we in India Yet?" "No... wait... now we are!"
- Homer: "Can't sleep. Gonna die."
- A literal example in "The Great Wife Hope": When all the men of Springfield abandon their usual hangouts to watch an MMA fight at the stadium, we get a shot of an empty Moe's Tavern, where the record player is stuck on a few-second-loop of "Monster Mash".
- Brother-Sister Incest: Cletus and Brandine are related to each other in all sorts of ways. One of them being as brother and sister.
- Subverted in "Money BART" in which Nelson makes an incest joke about Bart and Lisa's conversation, but Lisa retaliates that they're brother and sister, nothing more.
Milhouse: So are my parents. I think.
- Subverted in the episode, "Little Girl in the Big Ten", where Lisa is pretending to be a college student. When asked if any of the boys in her house are cute, she responds with "Well, Bart is kinda... NO!"
- Subverted in "Dangerous Curves". In the beginning of the third act of the episode, Bart and Lisa, while driving a pedal car along with Maggie, argue as if they're a 'married couple'.
- Subverted in "Kill the Alligator and Run" with this quote:
Homer: Yep, this place is great. And some day, when Lisa and Bart get married, it'll all be theirs.
Bart and Lisa: Yuck!
Marge: You mean when they marry other people.
Homer: Okay, but I ain't paying for two weddin's.
- Brought Home the Wrong Kid: Inverted; Grandpa is meant to babysit Bart and Lisa and goes to the Flanders' house by mistake.
- Played with in one episode, Homer was taking care of a bag of sugar in placement of a baby, yet when he holds it out, it's a blanket with a real baby. "Where's my sugar?" the scene changes to Cletus fondling the bag of sugar Cletus: Jr. feels more granulated than usual.
- Bubble Pipe: Bart blows in one when he falls in love with an older girl and ends up dressing like Hugh Heffner. And again when he visits the actual Hugh Heffner.
- Buccaneer Broadcaster: In "Wild Barts Can't Be Broken".
- Buffy Speak: In "Homer the Smithers", after Mr. Burns gives a series of tasks to Homer:
Homer: Um, can you repeat the part of the stuff where you said all about the...things? Uh... the things?
- Bullet Catch: In the pilot episode of "Police Cops", Detective Homer Simpson catches a bullet with his fingers and throws it back at the bad guy who shot at him in the first place.
- Bullet Dancing: Parodied in "Burns' Heir", in a flashback where Mr. Burns recalls performing this trick with a single shot pistol - firing, manually loading a bullet and powder into the muzzle, cocking the hammer, and firing again while the victim dances obligingly.
- The Bully: Nelson, Jimbo, Kearny and Dolph.
- There's also Francine Rhenquist in "Bye Bye Nerdie". The Francine example is an interesting case, as it reveals that she's a bully because she has an adverse reaction to the sweat that emanates from nerds. It was shown that it also affects Nelson (Lisa demonstrates by swabbing nerd sweat on boxer Dreaderick Tatum and Nelson compulsively begins beating him).
- Bully Hunter: Bart pulls the trope off in "Bart the General" when he and the entire class bombard Nelson and his gang with balloons until they surrender... literally, as in sign a treaty.
- Bumbling Dad: Homer.
- Bunny-Ears Lawyer: Ralph Wiggum, perhaps the most thoroughly and consistently moronic character in the whole show, shows a remarkable acting talent in the School Play biopic of George Washington. On the other hand, this was an early episode before his idiocy underwent Flanderization.
- Burning the Flag:
- In a Flash Forward episode Homer & Bart greet Lisa's British fiance by running the UK flag up their flagpole.
Bart: Here they come: raise the flag!
Homer does so; it sparks as it touches something electrical
Marge: Oh, Lisa!
Homer: Yo, Hugh! Here's a little bit of US hospitality: whaddaya think of that?
unbeknownst to Homer the flag is now on fire. Hugh gasps
he and Bart pull it down and stomp on it
Marge: Now throw compost on it! they do so
Homer: Whew! hands the flag to Hugh Er, enjoy.
Hugh: Oh...a tear forms it's still warm.
There's a lot of flag-burners
Who have got too much freedom
I want to make it legal
For policemen to beat'em.
'Cause there's limits to our liberties
At least I hope and pray that there are
'Cause those liberal freaks go too far.
- In the episode "Mr. Lisa Goes to Washington" Nelson writes a superpatriotic essay for a contest, for which this is his theme.
So burn that flag if you must! But before you do, you'd better burn a few other things! You'd better burn your shirt and your pants! Be sure to burn your TV and car! Oh yeah, and don't forget to burn your house! Because none of those things would exist without six red stripes, seven red stripes, and a helluva lot of stars!!
- Busby Berkeley Number: There are no lyrics, but in "Bart of Darkness", the swimmers perform a choreographed routine, part of which is shot from above and features a visual very similar to what's on the trope page.
- Butt Monkey: Quite a few, actually: Hans Moleman, Milhouse, Milhouse's dad after he got divorced, Grampa Simpson, Sideshow Mel, Gil, Homer, Bart (sometimes; see episodes "Bart's Girlfriend," "Miracle on Evergreen Terrace," "The Boys of Bummer," and "The Telltale Head")
- By "No", I Mean "Yes": From "The Springfield Files":
: I'm Leonard Nimoy
. The following tale of alien encounters is true. And by true, I mean, false. It's all lies. But they're entertaining lies. And in the end, isn't that the real truth? The answer, is no.
