The Grim Adventures of Billy & Mandy/Radar

In a similar vein to Rocko's Modern Life (and most, if not all, of Cartoon Network's original programming {we're looking at you, Ed Edd and Eddy, Cow and Chicken, Johnny Bravo, and especially you, Time Squad), |this show sneaked stuff past the censors all the time. The first season is a series of dark and violent shorts that Cartoon Network's censors (if any of them did anything remotely resembling a good job at monitoring content) wouldn't allow these days. After this angle was dropped, the show kept its edgy status by delivering at least one stealthy sex joke per episode. Not that the episodes still weren't still full of Nightmare Fuel and Dead Baby Comedy; it was there, but toned down. Here's some examples:

"Actress: Doctor, I'm pregnant! Doctor: That's the third time this week!"
 * The episode "Hill Billy" has Billy visiting Uncle Chokey the chicken juggler.
 * In "Here Thar Be Dwarves", Billy is cut off reading writing off a wall that says "For a good time call--".
 * In a very similar case, Professor Toadblatt mentions that someone from Weaselthorph House drew his picture on the restroom wall and added a "For a good time call..." message on it.
 * In one episode, Billy accuses Grim, among other things, of "watching Mom and dad's 'special' DVD."
 * In earlier episodes of the show, Grim watches TV programs with some barely audible but still somewhat dirty dialogue, such as:

"Dick: Yes, Irwin's mom is actually a mummy. Nobody can tell you who to fall in love with, but we've managed to make it work all these years. Leaving a whole lot of questions that don't need to be answered. Mandy: Eh, works for me. Grim: Me too. Billy: ...Yeeeeeaaah, but how did you and Irwin's mom... Dick: (in the exact same tone of voice) Leaving a whole lot of questions that don't need to be answered."
 * In one episode, Billy and Mandy find out that Irwin's mother is a mummy (as in, the Egyptian, wrapped-in-bandages kind), leading to this exchange:

"Pud'n': *grabs two chocolate eclairs* SUCK CUSTARD!"
 * "Honey! I have great news!" "You got the surgery!?"
 * In "Short Tall Tales" we get this: ""You set things right this very instant, or "I'll sue you so hard, your bank account won't know it's fees from its assets!"
 * From that same episode: "This ain't fair, yo! That thing's on 'ROIDS!"
 * One of the early episodes featured a swimsuit commercial for Speedos. Although it lasted only a few seconds... what a few seconds those were...
 * In the Shnissugah episode, how could someone forget it? When Grim Reaper tries to access the site, and commits a typo, it's made clear which site it went to... He even tries to conceal the page from the kids!
 * Another episode has Billy fail to recognize his de-aged mother, where he claims "My mother is ancient and grappling with the onset of menopause."
 * When Grim starts dating a goth girl, she asks, "So how do you know when someone's faking it?" and he suggestively says, "Trust me. I know," which prompts the girl to fake a painful screaming death. This is actually a Shout-Out to the "fake orgasm" scene from When Harry Met Sally....
 * Wishbones. It's pretty violent and filled with Family-Unfriendly Death such as an infamous scene in which Pud'n' wishes for a bunny. The segment ends with a bunny, with half of its body blown off, approaching an innocent little kid to probably kill him. Or the one where Skarr asphyxiates in the middle of space.

"Irwin: Good morning, Lady Mandy and... (snickers) Lady Grim. Grim: You better be quiet before I get medieval on your- Irwin: -AS I was saying..."
 * "Dracula don't suck! He licks!"
 * When Billy asks his father why he shaves, his father answers, ''When Daddy shaves his face, Mommy shaves her legs."
 * In "The Problem with Billy," Billy's father recollects of an "academic decathlon" Billy and Irwin did as toddlers. When the fathers meet, Billy's dad greets Irwin's with "Hi Dick!" to which he responds "Hi Harry!"
 * This exchange from the episode Terror of the Black Night:

""But don't you find me a-pealing?""
 * and yes, he pronounces it as "ass".
 * And of course, the leader of the Dinobonoids is called Professor Gaylord.
 * Doesn't sound like much 'til you see the rainbow on his helmet.
 * He gets beat up quite a lot in this episode too...Then again he was kinda a jerk.
 * "Ahoy, matey! Do you want to be a chocolate sailor?"
 * In "Everything Breaks", Billy breaks his umbilical cord while he's still in his mom's womb. That's a combination of Squick and Nightmare Fuel cranked Up to Eleven.
 * Toadblatt drank a love potion and he instantaneously fell in love with Squidhat, a singing male squid, and they proceeded to make out and get married. It should be noted that the Squidhat didn't drink any love potions.
 * In that same episode when Nigel Planter spots his love interest Herphenie Hefferpheffer, he just happens to be sitting on his broom. The handle goes upwards with a "sproing" sound effect; he then strokes and kisses it.
 * In the "Happy Huggy Stuffy Bears" episode, Irwin names his Happy Huggy Stuffy Bear "Mandy 2" and tells it that he is going to "teach (it) the meaning of looove" in a rather... suggestive manner.
 * "Sassy Cat, Sassy Cat, full of sass, full of sass, if you don't like it you can kiss. her. butt!"
 * Then there's Irwin in the Halloween special: "Hey, Mandy, have you ever kissed a banana?"

"Billy: "Okay I can explain that!""
 * Justified in that he was wearing a banana suit, and that Irwin IS known to make super lame puns often.
 * "Mandy'll take your pants off!" "...Beat your pants off." "Beat your pants off!"
 * In 'Keeper Of The Reaper' when Jeff is called to the stand, the judge asks him what his relationship is with Billy, to which Jeff replies, "He's my dad!" Everyone in the courtroom voices their disgust until Grim says, "He just hatched the egg, that's all!" and everyone sighs in relief.
 * When Billy is dancing to a song sung by a brain-shaped meteor he's seen dressed like a pimp.
 * That's actually a zoot suit (which, of course, is what the pimp suit was based on), much like the ones worn by anthropomorphic wolves in 1940s cartoons (to show that they're playboys looking to get laid) and, of course, The Mask (from the comic book, movie, and cartoon of the same name).
 * The narrator in 'Dream Mutt': "Now that's what I call doggy style!"
 * In the Mars episode when Mandy is about to fall from a platform Irwin says "I'll save you Mandy, grab my hand" and Mandy replies "Ew, no way, I know where that hand's been!"
 * One episode has Grim taking off his robe at a playground and shouting "Look at my body!" repeatedly at several children. It Makes Sense in Context.
 * It doesn't help that he gets arrested for it right after...
 * From the same episode, Grim starts rooting through Billy's room and finds a bra lying around.

""I like 'em large and in charge, mama!""
 * There's also the instance where Mandy has been cursed to grow whenever she's mean to someone. Needless to say, she's eventually several stories tall. Billy, however, rather approves of the situation.

"Nergal: And so you see, Billy, I'm a sad, sad failure. I can't ever show my face in that household again. Billy: Well, maybe you can show some other parts of your body."
 * This little exchange from "The Loser from the Earth's Core":

"Nergal Jr.: Ewww. Old people love."
 * In "Substitute Teacher", Nergal and Aunt Sis start nuzzling, before the camera rapidly cuts to show their son Nergal Jr. looking revolted as assorted... questionable sound effects occur from the off-camera antics:

"Billy and Irwin (singing): Well, we built our go-cart all by ourselves, and if you don't like it, you can go to...heck!"
 * in " Billy Gets an A" Irwin asks Mandy to be his study buddy, then continues to say "we can stay up all night together...studying"
 * In the go-cart race episode:

"Dracula: Well, if you didn't make your babies so delicious, Dracula wouldn't have had to eat 'em!"
 * PET MAH BELLEH!
 * This line from Dracula can sound extremely and horribly wrong especially if used out of context

"Grim: Come on, Mandy. This should be fun... like watching a train wreck. Grim: (laughs) This is more fun than the French Revolution!"
 * In the same episode, Grim says "But you're a vampire, and vampires suck...blood!"
 * A rather interesting (and quite expected) one can be seen on the halloween special "Underfist." When Hoss Delgado is freed from Mindy the Witch's binds, he readys his chainsaw/crossbow/fist thing and growls "Who wants the first spanking?" to an army of mutant brownies. If you look close, you can see one raise it's hand...
 * Grim's rather macarbe phrases can be considered the next best thing to mentioning death in the show.
