You might be wondering why a show like The Simpsons would have a Getting Crap Past the Radar page, seeing as how it's not supposed to be for kids in the first place note despite that when The Simpsons first became a 30-minute animated sitcom, a lot of Moral Guardians protested against Bart's subversive behavior and condemned the show as trash because people were still accustomed to thinking that cartoons were for children — despite that there were adult cartoons prior to The Simpsons, such as The Flintstones, Wait Till Your Father Gets Home, and Fritz the Cat, bright colors and crude, childlike character designs nonwithstanding.
Thing is, it's still subtle enough about its dirtiest, most subversive moments that some consider it still acceptable enough at least for older kids, since even kids who realize that it's a dirty show probably don't realize just how dirty it is.
"Isabels's only 8. As she gets older amazing things will happen to her body." said by Marge to Lisa in "The Kid is All Right".
Bart intoning brand name condoms for a magic spell ("Trojan, Ramses, Magnum, Sheik!") to get the town's zombies back to their graves ("Treehouse of Horror III"; the "Dial Z For Zombie" story).
Krusty wondering if he should tell the joke about "the twelve inch pianist" during Selma's wedding video ("Black Widower" note Season three episode in which Selma marries Sideshow Bob, and Bart is convinced that Bob is going to kill her).
Also from "Black Widower":
Sideshow Bob(as he's accepting his Daytime Emmy award): This is one more award than you'll ever win, you blithering jack-in-the-box.
Disco Stu hitting on Bart during the Odyssey segment of "Tales from the Public Domain," a reference to the acceptance of pedophilia within ancient Greek society.
Also from the Odyssey segment, we have Ned Flanders as Priam's Accidental Innuendo line regarding the Trojan Horse. Which is lampshaded by Homer's laughter afterwards:
Ned Flanders as Priam: When people get new wood, they'll think of Trojans!
Marge whispering to Homer what the Washington Monument resembles on the season 3 episode "Mr. Lisa Goes to Washington" note The episode where Lisa enters a "Why I Love America" essay contest — and inadvertently takes down a corrupt senator when she rewrites her essay to rat him out and defame America. ("Oh, grow up, Marge!")
On the season eight episode, "Homer's Phobia," John tells Marge that Helen Lovejoy's "cuffs and collar don't match"note (saying someone's "cuffs and collars" don't match is the same as saying the "carpet doesn't match the curtains" — it means the hair on someone's head doesn't match his or her pubic hair, often due to a dye job). On the commentary, the writers are still amazed that the censors let that slide past (despite that "Homer's Phobia" was almost banned for its content — at the time, doing an episode about homosexuality and homophobia was either not done or written as a very special dramatic episode. It was saved from being banned thanks to a change in management, but the censors still asked the writers to remove or tone down some lines for being too homophobic or sexually suggestive for primetime TV).
In the episode "Brother From the Same Planet", Homer and Bart are having an argument. Homer asks Bart if he remembers how he used to have fun pushing him on the swing, which Bart denies, and says he was "faking it". Homer calls him a liar, and Bart then enthusiastically starts to say "Higher, Dad, Higher! Whee!" to prove his point.
The page image, the most well-known dirty joke of the series. note If you don't get it, it used to be called Chuck's Fuck and Suck.
In a recent episode ("Flaming Moe"; not to be confused with the season three episode where Homer invents a fiery cocktail and Moe lies and says he invented it so his bar can have more business), Smithers and Moe open a gay bar, and at one point Mr. Burns comes in to see what Smithers has done. A Manly Gay hollers at them, saying "Hey, Smithers, I didn't know you were a geezer-pleaser! Having a lemon party?"
Burns's reply: "Ohoho! A good old-fashioned lemon party! I call first squeeze!"
Lemon Party was also referenced one season later in "Politically Inept with Homer Simpson"note the one where Homer gets his own cable political show after video footage of him going berserk on a grounded plane and ranting about how bad airport security — and America — has gotten over the years goes viral when Homer mistakes the Founding Fathers signing the Declaration of Independence for the shock site ("What is this, a bicentennial Lemon Party?").
On the DVD commentary, the writers were surprised they got away with "Flaming Moe's" (the season three episode in which Homer creates that alcoholic cocktail out of Krusty Brand kids' cough syrup, not the later-era episode where Moe and Smithers revamp Moe's as a gay bar), though "moe" (meaning "homo," not pronounced "mo-ay") isn't that common a slang term. Though they do come dangerously close when Homer is about to state the name of the drink and is interrupted by Moe:
Homer: It's called a Flaming H-
Moe: Moe. It's a Flaming Moe. I'm Moe.
Not to mention what else cough syrup is used to secretly produce...
The 451st episode ("Once Upon a Time in Springfield") had Anne Hathaway as Princess Penelope to bring in more female viewers for Krustys show. It turns out she's had a crush on Krusty since she was little, then makes out with him. The act ends when Krusty's trick boutonniere squirts.
From the Treehouse of Horror episode with the dolphins: "Don't forget - we invented computers, leg warmers, bendy straws, peel-and-eat shrimp, the glory hole, AND the pudding cup!"
Roger Myers' reply to Marge's concerns over the violence in Itchy 'n Scratchy.
Myers: "In reply to your specific concerns about the cartoon, it's been shown that no one crackpot can change the world on their own, so let me conclude by saying..."
Marge: "...and the horse I rode in on?!?!?"
From King Homer in "Treehouse of Horror III" (in probably one of the rare times that Mr. Burns seems like he knows that Smithers is a homosexual, though it probably doesn't count since Halloween episodes are non-canon):
Smithers: I think women and seamen don't mix.
Mr. Burns: We know what you think.
On the season 12 episode "HOMR" (the episode in which Homer discovers that the reason why he's dumb is because of a crayon he had lodged in his head as a kid) had this exchange between Lisa and Marge (which could be taken as an innuendo):
Lisa: Well, maybe if Mom didn't make such dry waffles. There, I said it.
Marge: Well, maybe if you'd eat some meat you'd have a natural lubricant.
An episode featured Homer working as an ice-cream man and Marge using the used sticks to make wood figurines (season 18's "Ice Cream of Margie With the Light Blue Hair"). A later scene in the bedroom says that Homer has "...never been happier giving Marge wood".
In "Much Apu About Nothing", Apu reveals that he came to America to attend Springfield Heights Institute of Technology. The initials are never shown, but smart viewers will know what it spells out.
During Maggie's dream in "The Fight Before Christmas", all of the normal characters are muppet versions of themselves, except for guest-star Katy Perry, who in the dream is Moe's girlfriend and also a live action human being. As you may expect, this makes her much taller than Moe. After the credits have rolled, Moe is shown repeatedly jumping up so he can be near her face long enough to give her a kiss, and repeatedly failing. Finally he says that he'll just kiss her bellybutton...and his aim's a little bit low.
Katy:Oh, uh, that's not my bellybutton. (beat): But I didn't say stop!
Season nine's "Bart Star" had a flashback in which Lenny wore a shirt with "Bull shirt" written on it.
The season 16 episode, "Fat Man and Little Boy" has Bart selling T-shirts with sarcastic slogans on them as a means to cope with the fact that he lost his final baby tooth and isn't going to be a child anymore. One of the shirts he sells reads "Pobody's Sherfect, Nithead".
Speaking of raunchy shirt slogans, the season seven episode "Two Bad Neighbors" note the one where George H.W. Bush moves next door to The Simpsons had a shirt Homer once wore that reads, "Ayatollah Assahola." The only reason the writers and animators got away with that was that one of the two "S"'s was always obscured. This was also the same case in "Hurricane Neddy" from season eight during the scene where one of Flanders' kids wears a "Butthole Surfers" T-shirt (the last part of "butthole" was obscured by a T-shirt wrinkle).
Rude: Oh that sounds lovely. [coughs "queer" twice]
From "Last Tap Dance in Springfieldnote the episode where Lisa wants to become a ballet dancer, but ends up in a tap class taught by a Shirley Temple-esque former child star of the 1930s: she and Marge are watching a movie about "El Tango de la Muerte". It features a shy, nerdy librarian who becomes a hot dancer and a Mexican expy of Milhouse who, after seeing the girl going away with a handsome man, says this:
From "A Tale of Two Springfields", after the other side of the town discovers gold
Kent Brockman: (on TV) "Thanks Mayor Simpson. Because of you, we’re all taking golden showers!
[production staff snickers in the background]
"Two Dozen and one Greyhounds", where Santa's Little Helper finds a mate, was developed so the writers could get this exchange in, somewhat subverting the trope in the process:
Bart: Aw. Me and Santa's Little Helper used to be a team, but he never wants to play anymore since his bitch moved in.
Marge: Bart, don't ever say that word again!
Bart: Well, that's what she is. I looked it up.
Marge: Well, I'm going to write the dictionary people and have that checked. Feels like a mistake...
A similar joke was done on "O, Brother Where Art Thou?"note The episode where Homer finds out he has a long-lost half-brother, where Bart calls Homer's long-lost half-brother a "bastard" — not as an insult, but because Herb was born out of wedlock (for context: Grampa Simpson had sex with a dunk-tank worker at a carnival who liked to have sex with men for money. When she came back a year later, she had baby Herb in her arms and the two decided to give him up for adoption, since neither of them wanted him). It Crosses the Line Twice when Bart begins singing, "Bastard" nine times during the family drive home from the hospital.
In the UK, "bastard" is a much harsher curse word than it is in America (or even Australia) and when the episode aired, some UK TV channels either cut the entire scene after Homer tells Grampa that he's going to find his brother or cut off after Bart explains that he was using "bastard" in the "child of unmarried parents" sense, and not the rude word for a person.
Homer calling "GBM" (a "gay black male") in "El Viaje Misterioso De Nuestro Jomer"note translated: "The Mysterious Voyage of Our Homer," It's the season eight episode where Homer eats an extremely hot chili pepper from Guatemala and ends up in a psychedelic world where a space coyote tells Homer to find his soulmate.
The episode "Skinner's Sense of Snow" has two standouts. After suffering much verbal abuse at the hands of Principal Skinner, Groundskeeper Willie announces he'll do no more work with the line "That's the last time you'll slap your Willie around." Later, while tied up in a burlap sack used to store dodgeballs, Skinner tells the school hamster "Quick, Nibbles, chew through my ballsack." The hamster squeaks in disgust and leaves.
From "Hurricane Neddy," when Flanders' doctor was showing him film footage of how he used to act as a kid:
Ned: I'm Dick Tracy! Bam! Take that, Prune-Face! Now I'm Prune-Face! Take that, Dick Tracy! Now I'm Prune Tracy! Take that, Dick—
Dr. Foster: Stop that, Ned!
Black-Eyed, Please," when Ned punches Homer. He wants Homer to punch him ("Eye for an Eye") and shows up at the power plant.
Ned: I'm insisting on a fisting.
Smithers: What's this about a fisting?
Earlier in the same episode, a substitute teacher named Ms Cantwell is introduced, and Skinner tells the children not to make the obvious joke with her name (which can't even be made on TV). He then proceeds to consult a depressed teacher named Dick Testiclees.
A similar joke was made back in "Separate Vocations"note season three episode where Lisa and Bart take an aptitude test and the results have Bart as a police officer — which leads to him cleaning up his act and becoming hall monitor, while Lisa becomes a bad kid after discovering that she can't be a jazz musician because of stubby fingers when Skinner assured another teacher that "no one will make fun of your name anymore, Mr. Glascock."
Homer: Let's just say the stories about him are greatly exaggerated.
In "I Love Lisa", Chief Wiggum tells the kids that he met Krusty (and got tickets to his anniversary special) while eating popcorn in a porno theater (in a reference to what happened to Paul Reubens after Pee-Wee's Playhouse ended in the early 1990s):
This one sorta doubles as Genius Bonus, but in "The Parent Rap"note the one where the new judge Constance Harm appears and starts imposing harsh punishments on parents of delinquents Judge Harm says "If I want a cock-and-bull story, I'll read Hemingway, thank you". Ernest Hemingway once wrote a story about a matador (hence the bull) who had troubles in bed (hence the cock).
Also in the episode, when Bart goes to confess to Judge Harm and get his parents off the hook, Harm allows it, because Bart reminds her of her, when she was a little boy.
Lisa: *With happy tears in her eyes about Bart's confession* That's my brother...
Snake: Did...she just say she used to be a dude?
In Husbands and Knives, the sub-plot is a new comic shop opening in town that displaces the sarcastic and unlikeable Comic Store Guy. The East Midlands' finest comic craftsman, Alan Moore, is seen talking comics with a very prominent poster behind him advertising something called Lost Girls. The poster shows two girls looking adoringly and lovingly at a third...
In "Homer vs. Dignity" (which was already considered depraved because of the scene of Homer getting sexually assaulted by a panda), while Comic Book guy is eating marshmallow Peeps he utters the line:
Comic Book Guy: If only the real chicks went down this easy.
In Bart Star after Homer designates Bart as the new quarterback, Bart sheepishly says, "Give me a 'B'?" Nelson says, "I won't give you a 'B', but I'll tear you a new 'A'."
Just the title Whacking Daynote An episode about a Springfield "holiday" where everyone beats snakes with sticks. If that weren't enough, there are a couple bits in the show itself. First, Homer asks if he should whack fast or slow, and Marge says, "Slow, then fast," with very aroused eyes. Later, Miss Springfield opens the event by saying, "Gentlemen, start your whacking!"
In the episode "Specs and the City" during the montage, Bart's penis is visible for a few frames.
In "All's Fair in Oven War" Homer says Marge is the best chef of their house and Marge says, "Eh, BFD."note Big Fucking Deal
