Western Animation / The Grim Adventures of Billy & Mandy

Go To
Billy: Oh, oh, look! It's Santa, Santa Claus!
Mandy: That's not Santa, you stooge. That's the Grim Reaper.
Billy: Do I still get presents?
— "Meet the Reaper"

The Grim Reaper has come for a soul — specifically, a hamster in his dying days — but he's thwarted from taking the hamster to the afterlife by two polar-opposite children: the blissfully idiotic Billy (the hamster's owner) and his cynical, amoral best friend Mandy. The pair challenge "Grim" to a limbo contest to save the hamster; when Grim loses (through Mandy's cheating) he becomes Billy and Mandy's newest friend — and by "friend," we mean that he's contractually bound to cater to their every whim.

Grim is now (begrudgingly) forced to serve as something of an underworld version of Mary Poppins, thanklessly placating Billy's demands for cheap entertainment and Mandy's schemes for self-profit with his magical scythe while desperately trying to find a way to be rid of the duo for good. Thus goes The Grim Adventures of Billy and Mandy, an absurd Horror Comedy series created for Cartoon Network that combines dark comedy, slapstick, and eldritch horror themes reminiscent of those found in H. P. Lovecraft's novels.


Rounding out the show's cast are Billy's parents Harold and Gladys, who have unfortunately passed their respective stupidity and insanity onto their son; Irwin, Billy's other best friend and the Token Minority (who also has a massive, unrequited, crush on Mandy); Sperg The Bully; Mindy the Alpha Bitch; Pud'n, Billy and Irwin's sometime-friend; Hoss Delgado, a supernatural bounty hunter with more brawn than brains; Eris, the goddess of chaos and discord; General Skarr, formerly seen in Evil Con Carne, who moves in next door and now wants to just garden instead of conquer the world; Nergal, the Sumerian Death God who lives in Earth's molten core and just wants to be friends with everyone, really; Nergal Jr., Nergal's son and Billy's cousin; Jeff, a friendly Giant Spider who's convinced Billy is his father (much to Billy's horror); a Redd Foxx-inspired version of Dracula who is Irwin's grandpa; and Fred Fredburger, a green Cloudcuckoolander demon...thing who is just as dimwitted as Billy, if not more. Adventures abound as the human duo and their unwilling friend interact with others in their lovely little town of Endsville, facing down all sorts of opponents, from the school bully to sometimes homicidal neighbors to Eldritch Abominations born from the most terrifying pits of the human mind.


Created by former Cow and Chicken artist Maxwell Atoms, the show was the winner of the first Big Pick, a contest where viewers got to vote what pilot would be greenlit to be the next Cartoon Cartoon. The series was also originally paired up with another Maxwell Atoms cartoon, Evil Con Carne, to make up the Three Shorts show known as Grim & Evil. This early version of the show put more emphasis on the "horror" part of horror-comedy, becoming more goofy and comedic (but still pretty dark) when the two shows were separated into their own series.

The cartoon lasted seven seasons (2001-2008) with two Made For TV Movies; Billy & Mandy’s Big Boogey Adventure and Wrath of the Spider Queen, a couple of specials — including a crossover with Codename: Kids Next Door note  — and a spin-off attempt called Underfist: Halloween Bash.

This show provides examples of:

    open/close all folders 

  • Accidental Misnaming: "Guess What's Coming to Dinner" had a running gag of Eris and Hoss Delgado getting Principal Goodvibes' name wrong, often addressing him with different names beginning with the word "good" such as "Goodwater", "Goodchild", and "Good Burger".
    • In that same episode, Hoss can't remember Billy's name either, referring to him as Randy, Otis, and Remus.
  • Acquainted with Emergency Services:
    • In Season 2 "Educating Grim", when Billy tries to race Grim and Mandy to school, he immediately runs into the school's front sign. Cue Nurse Penbroke walking outside hold first-aid kits looking annoyed. After Billy and Mandy leave school, Billy is already covered in bandages and walking with a crutch. When Nurse Penbroke happily waits outside for Billy, he tells her he's done for today and then she releases an exhausted sigh.
      Nurse Penbroke: Oh, Billy.
      Billy: (cheerfully) Hi, Nurse Penbroke. I can't feel my legs.
    • Grim has this relationship with the nursing staffs at the retirement homes when he comes for the elderly residents, as shown in Season 5 "Home of the Ancients".
      Gloria: Hi, Grim.
      Grim: S'up, Gloria.
      Gloria: Aw. Are you here for Mr. Silverman?
      Grim: No. That's next week.
  • Actor Allusion:
    • In the two-part episode, "Brown Evil", Billy mistakes Hoss Delgado for a wussy video game character named Pat the Baker, both of which are voiced by Deiderich Bader.
    • Dean Toadblatt's voice actor is John Vernon, the same guy who played Dean Wormer in Animal House. This explains why he yelled "Gunderstank House!" after getting pranked on the episode where Billy and Mandy go to a Hogwarts-style school for kid wizards.
    • In the Christmas Special, the vampire Baron von Ghoulish, voiced by Malcolm McDowell, is first seen filing his teeth and singing Singin' In The Rain.
    • Two episodes feature Kurtwood Smith as Grim's dad, who is pretty much a skeletal Red Forman in terms of appearance and mannerisms.
  • Alpha Bitch: Mindy, especially in the final Halloween special of the show.
  • Alliterative List: Trying to help Nergal to make friends, Billy introduces him to the five C's of friendship. Cleanliness, Consideration, Compliments, Conversation, and, uh, Sharing.
  • Alternate Universe: It shares the same universe as Evil Con Carne, a universe where Abraham Lincoln is still President and the League of Nations still exists. It's also hinted that it shares the same universe as Codename: Kids Next Door and Ed, Edd n Eddy, per the crossover. In one episode, due to the collapse of time and space, the universe is rebooted and the characters are reincarnated as the cast of The Powerpuff Girls... which might also be part of the same universe anyway, since Billy's first reaction upon seeing the Kids Next Door is to comment that they're not the Powerpuff Girls.
  • Ambiguously Related: While it ultimately ends up not being the case, the first couple episodes aren’t very clear as to whether or not on Billy and Mandy are siblings. The Pilot Episode makes no mention of what their relationship is and it ending with the two of them (and Grim) sharing the same bed certainly didn’t help matters. It isn’t until Mandy's parents are introduced is it more or less confirmed that Mandy simply just spends her free time at Billy's house. A gag in a later episode even lampshades the fact that she almost never goes home.
  • And Now You Must Marry Me: Miss Butterbean pulls a non-villainous example of this after being kidnapped by Fred Flintstone in "Modern Primitives". He... doesn't react well.
  • Anime Hair: Eris in "Creating Chaos", whenever she's enjoying herself. "CHAOS!!!"
  • Animesque:
    • Also used for a quick one-off gag when Grim was trying to use his magic to fix Billy's eyesight, Grim and Mandy appear in his eyes in an anime style. Somehow, this includes speaking Japanese.
    • At the end of "My Fair Mandy", it turns out to be The Powerpuff Girls, another somewhat Animesque show.
  • Apple for Teacher: In "Smarten Up!", when Billy's cat Milkshakes, possessed by a "book worm", takes it upon himself to tutor him. Billy gives him an apple, which touches Milkshakes until he find a worm in it.
  • Armor-Piercing Slap:
    • Mandy tends to give these to Billy, sometimes because he says or does something stupid and occasionally for no reason at all.
    • A trademark of the Booty Heads is a two-handed version of this trope. After the simultaneous double slap, the victim is left with red swollen cheeks and a submissive attitude to the aggressors. Billy and Harold are perfect examples of that.
  • Armor-Piercing Question: In the episode "Grim in Love", Mandy gives one to Grim regarding his new goth girlfriend, Malaria.
    Mandy: So I take it your date went well?
    Grim: I’m King of the Underworld!
    Mandy: Have you told her you’re not human yet?
  • Arson, Murder, and Jaywalking:
    • Billy's dad's lucky pants are immune to lasers, supernatural forces, and mustard.
    • In "Night of the Living Grim", Grim does this when he complains about his Humanity Ensues situation.
      Grim: I hate being mortal. I have no powers, I get beat up every two minutes, I have to go to the bathroom all the time…
    • In "Bully Boogie", the Boogeyman blames kids being hard to scare nowadays on cartoons, video games, and the tuba.
    • In "Complete and Utter Chaos", when Mandy takes the Apple of Discord and plans to use its power herself, she goes on a long rant of everything she will do, such as ruling humanity and being a "dark and terrible queen", and then finishes it by saying "and I might punch Irwin in the mouth!" just as dramatically.
  • Art Evolution: Lampshaded in "Billy and Mandy Begins", where scenes from the original episode accompanied by Mandy's narration are played to end the dispute over the character's conflicting origin stories. Grim remarks, "That doesn't even look like us!"
  • Art Shift: An episode ended with Billy needing Grim to fix his eyes, and with each attempt, he sees the world rendered in a different animation style, until finally, he gets real human eyes.
  • Aspect Ratio Switch: The final season (including "Big Boogey Adventure" and "Underfist") saw the switch from 4:3 to 16:9. The KND crossover was, however, produced in 4:3 since it was a Kids Next Door episode.
  • Assimilation Backfire:
    • Happened to a brain-eating alien, when it was dumb enough to consume Mandy's brain. Mandy takes over and gets the same craving for brains as the alien.
    • Happened again in the Kids Next Door crossover. Billy getting Grim's scythe stuck in his father's pants combined with overloading the Delightful Children's Delightfulization device causes them to meld into a giant Hive Mind Reaper entity that assimilates every person it reaps. Mandy intentionality lets herself be assimilated, as she knows her willpower is strong enough to overpower the rest of the collective consciousness in the Reaper.
  • An Ass-Kicking Christmas: Billy and Mandy Save Christmas.
  • Apocalypse How: Played for laughs at the end of the episode "My Fair Mandy" when Mandy smiles, causing a Class X-4 apocalypse, leading to the trio having replaced the The Powerpuff Girls.
  • Attack of the Political Ad: Kind of- Grim and Nergal duke it out over their own pizza recipes in one episode; their ads duel each other, mocking each other- ie. when Nergal claims that Grim puts bugs in his pizza, Grim counters with Nergal's supposed usage of dirty socks and underwear.
  • Attractive Bent-Gender: Averted. When Sperg the bully gets ahold of the wish-granting skull, the only thing on his mind is being able to go into the girl's restroom to rob them all of their money. Cue him turning into a girl so he can go in there, but the girls ridicule girl-Sperg for being such an ugly girl that he/she runs out crying. "Girls are so mean!"
  • Autocannibalism: Billy is turned into chocolate, and finds himself so irresistible that he eventually eats himself down to just his head. Apparently, he's not the first to do so.
  • Awesome Mc Coolname: Billy's Martian pet, "Admiral Wolverine Lightningbolt."
  • Badass Crew: Underfist, natch.
  • Bad Santa: Voiced by Gilbert Gottfried in a Christmas episode/movie. Actually, Santa isn't really bad, he's just occasionally turned into a vampire by Mrs. Claus, who was a vampire before they married. That's happened quite a few times before.
  • Balloon Belly: Billy sometimes gets a big belly when he binge-eats.
  • Bat Family Crossover: In the episode "Company Halt", Skarr gets a visit from his ex-co-workers Hector Con Carne and Major Ghastly, as they reinstate the Evil Con Carne criminal organization, develop a new diabolical weaponnote  and use it to terrorize the citizens of Endsville. Needless to say, Grim, Billy and Mandy go out and stop them.
  • Batman Can Breathe in Space: Ordinarily played straight, then averted in "Wishbones": Skarr wishes to Thromnabular that he could rule the world, and a giant statue of himself rises up beneath him. As Skarr is talking down to everyone, he doesn't notice that the statue is extending up into space, where he suffocates and explodes.
  • Batty Lip Burbling: By the end of "Opposite Day", Billy and Mandy pointed out that when they said it was Opposite Day, that meant that it actually was not Opposite Day and that they had tricked him into doing all of their chores. Having spent the whole episode confused beyond his wits, Grim responds by motorboating his lips while hitting his head with a mallet.
  • Bears Are Bad News: Billy has to run from a disheveled Yogi and Boo-Boo in "Here Thar Be Dwarves!".
  • Beware the Silly Ones: Billy is often the dumbest one on the show, but he has been shown to have bouts of psychotic rage that scares even Mandy.
  • Bigger on the Inside: Grim's trunk. Billy points this out by name in one episode when he, Mandy, and Irwin climb inside it. Also, Hoss Delgado's tank from Underfist.
  • Big Beautiful Woman: The Valkyries from "A Kick in the Asgard".
  • Big "NO!": Regularly used by Billy and Grim, though Mandy gets one when she's unwillingly turned into a milk-themed superhero in "Billy & Mandy Moon the Moon", while Irwin gets one when he's sealed in his newly-built pyramid in "King Tooten Pooten".
  • Bilingual Bonus:
    • The Dwarven battle cry is "laven sus manos", Spanish for "wash your hands". The Mexican dub didn't even bother changing it, it was considered funnier that way.
    • One of Hoss Delgado's Pre Ass Kicking One Liners is "Piso mojado, dirtbag!" Spanish for "Wet floor, dirtbag!"
  • Bizarrchitecture: In "Substitute Creature" it's shown that Endsville Elementary is built on a mesa overlooking a desert. This was likely just for a one-time gag, as later episodes depict the school having a football field.
  • Black and Nerdy: Irwin, who in spite of being a nerd is just as dumb as Billy. He even tried cheating off of Mandy's answers on a test.
  • Black Comedy: The whole genre in the series. One of few kids shows with it, combined with Grossout Show.
  • Bloodless Carnage: Despite being one of the most violent shows in Cartoon Network's catalogue and having some genuinely brutal slapstick, actual sights of blood are very rare.
  • Bloodsucking Bats: Discussed. Dracula himself clears up the misconception about vampires. Contrary to popular belief, vampires don't suck the blood of their victims. Bringing up the comparison to actual vampire bats, they scrape and lick their victims.
    Dracula: Dracula don't suck!
    Grim: You're a vampire! Vampires suck! Blood!
    Dracula: Naw, ya see, dat's a myth, Dracula scrape wit' his fangs an' then lick up the blood, like this.. (wiggles his tongue) See? Scrape and lick. (wiggles his tongue)
  • Broken Record: "DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! DESTROY US ALL! I'll take the chicken. DESTROY US ALL!" Also doubles as a Madness Mantra.
    • Fred Fredburger, Fred Fredburger, Fred Fredburger, Fred Fredburger, Fred Fredburger, Fred Fredburger, Fred Fredburger, Fred Fredburger, yes!
      • Judge? (No! Shut up!) Judge? (Shut up!) Judge? (I order you to shut up!) Judge? (WHY WON'T YOU SHUT UP?!!) Judge?
    • In "Scythe for Sale", when Irwin rejects the worthless junk being sold at Billy's garage sale, Billy fires away his machine gun mouth with an infinite ammo of "COME ON COME ON COME ON COME ON"
  • Broke the Rating Scale:
    • Billy managed to score himself a NEGATIVE 5 on an IQ test, being outperformed by a shovel and a pair of candy bracelets.
    • In "Substitute Creature", Mandy somehow scores an A with six pluses on her test.
  • Butt Cannon: In the episode "It's Hokey Mon!", one of the many eponymous Hokey Monsters has a literal cannon in its butt, which another Hokey Monster loads cannonballs in manually.
  • Butt-Monkey:
    • Grim and Billy, naturally, but "Super Zero" had this adorable alien creature, who wanted to be Billy's friend, but kept taking Billy's constant, near-lethal abuse. When Billy finally notices him he decides to call him Winston and take him back to Earth, but he falls off Billy's shoulder and gets left behind.
    • Nergal doesn't start out this way, but as of "Loser from the Earth's Core," this becomes one of his defining character traits — including a cameo during "The Incredible Shrinking Mandy" solely for the purpose of having him be crushed by random falling things. Even lampshaded slightly in "Underfist," when his family knows something bad is coming because he brought up how well things are going for him...
    • Let's not even start on Irwin.
      • Or Pud'n.
    • There's also Tom Smith from "The House of No Tomorrow".
  • But for Me, It Was Tuesday: In "Nigel Planter and the Order of the Peanuts", Nigel Planter goes back to his old school to act out his revenge, only to find that Dean Toadblatt doesn't remember him.
    Toadblatt: I torment thousands of students every semester. I can't be expected to remember them all!
  • Call to Agriculture: Skarr, the Canon Immigrant from Evil Con Carne just wants to be left alone and do his gardening. He gets his wish by turning into a plant, but with dangerous results.
  • The Cameo: Scooby-Doo briefly appears in "Keeper of the Reaper" to testify against Mandy, who apparently mocked his speech impediment.
  • Canary in a Coal Mine: In "The Secret Decoder Ring", the secret of the universe can be found at the bottom of a mind shaft where the ghosts of canaries can be seen flying in and out, and couple of cockatoos and toucans and kiwis.
  • Captain Ersatz: Occasionally an obvious reference to a non-Cartoon Network property (such as Hellraiser or The Little Mermaid) will appear, lampshading how clear of a ripoff they are by starting to say the original character's name before cutting themselves off and saying a parody name.
  • Casting Gag:
    • The Latin dub has a sort of one with Nigel Platter, as the VA that voiced him actually voiced Harry Potter too.
    • This isn't the first time Phil Lamarr voiced a vampire.
  • Characterization Marches On: In the first episode she appeared in, Eris acted like a typical giddy blond teenage valley girl. Afterwards though she acted more regal and queenly with a British accent. Also a Shout-Out to Madonna.
    • By her next appearance, her personality change is lampshaded and Hand Waved away by her going through "a Valley girl stage" as is Grim's crush on her during that episode/stage. She also turned into a boyfriend-eating woman that dated and dined on Hoss more than once.
    • Mandy used to smile on occasion — though, usually after doing something horrible to the human race. In a much later episode, Mandy smiling tears apart the fabric of space and time.
      • Mandy started out as an apathetic Anti-Hero before becoming a sociopath who only saves the world so it will be free for her later, takes pride in being utterly evil, and suffers physical strain to say "please."
    • Grim wanted to kill the kids at first, but later decided they're his only living friends and will do anything to avoid their doom.
    • In the first few episodes, Mandy forbids Grim from reaping people. It wasn't long before just about every episode has jokes about Grim's job.
  • Chekhov's Gun: From "Meet the Reaper," "Kiss kiss." note 
  • The Chew Toy: NOBODY in this show is safe from this trope. Yes, that includes Mandy.
  • Christmas Cake: Parodied with the host of Grim's favorite late-night show, Atrocia, whose show was cancelled the moment she turned 30.
    "The network said no one wants to see a worn-out old bag like me on TV anymore."
  • Circus Episode: "Circus of Fear", where Grim goes to an underworld circus with Billy and Mandy, who end up getting kidnapped by the ringmaster Doctor Fear.
  • City of Adventure: Endsville. Billy, Mandy, and Grim are always finding an adventure and forces of evil to thwart.
  • Cloudcuckoolander: Billy and Fred Fredburger both tend to have very odd beliefs and habits.
  • Comically Missing the Point: In "Substitute Creature", when Nergal Jr. as Ms. Butterbean fails Billy on a math test for drawing a clown with a flamethrower in place of an answer, Billy remedies it by adding a pirate hat.
  • Comic-Book Adaptation: Comic stories based on this show were featured in Cartoon Cartoons and Cartoon Network Block Party.
  • Comic Trio: Mandy is the schemer, Billy is the follower, and Grim is the complainer.
  • Company Cross References:
    • In "Sickly Sweet", Grim is watching Codename: Kids Next Door.
    • In "Herbicidal Maniac", Cow giving Skarr a bag of manure for his garden, while Johnny Bravo makes a background cameo at Skarr's party.
    • In "Billy and Mandy vs. the Martians", Billy sees a giant holographic screen and laments "Hey, this isn't Codename: Kids Next Door!"
    • A Ham Being from the I Am Weasel episode "The Magnificent Motorbikini" appears in "The Incredible Shrinking Mandy" as one of three giant beings who were growing infinitely in the Realm of the Infinite.
  • Confirm Before Reveal: In Season 7 "Yeti or Not, Here I Come", when the trio are trying to catch the Yeti and the Yeti brings them to his home, they pass by a glacier and he tells them that a glacier can move six feet a day. After the Yeti escapes them several times, Grim finally corners him at the same glacier they passed by. Grim pulls out a tape measure and asks the Yeti to remind him how far can a glacier travel in 24 hours while measuring how far the glacier will move, the Yeti reminds him six feet and asks for his point, and then Grim reveals that it's about to be midnight right now and the glacier moves and crushes him.
  • Conjoined Twins: Hoss Delgado and Billy at one point encounter a pair of conjoined twin zombies in the episode "Brown Evil". Hoss slices them into ribbons as soon as he sees them.
  • Cool Old Lady: Mrs. Doolin in "Who Killed Who?". The fact that she's voiced by Betty White certainly helps.
  • Cool Plane: Underfist was intended to have the "Fistflyer", with speeds of up to Mach 4; like Hoss' tank, it's got a giant metal fist mounted to the front that Jeff would use to punch threats. It's briefly glimpsed during the credits of the Underfist special.
  • Couch Gag: A message to the viewers, usually from Mandy, at the end of the theme song.
  • Cranium Chase: Grim is a constant victim of this.
  • Crapsack World: Many episodes show that Endsville is a pretty bad place to live in, even without all the Lovecraftian horrors that makes Dunwich, Massachusetts seem uneventful by comparison that the main characters have to deal with on a frequent basis. Though if the Codename: Kids Next Door crossover is to be believed, it's confined to Endsville, and the rest of the world is just fine.
  • Creator Cameo: Show creator Maxwell Atoms appears in one episode, just long enough to poof out of existence after Billy breaks the hourglass representing his lifespan.
  • Crossover: Sort of. Numbuh 3 appeared four times in Big Boogey Adventure.
    • In "Modern Primitives," Billy finds Fred Flintstone frozen in his backyard.
    • Early on in "Here Thar Be Dwarves," Billy's picnic is interrupted by Yogi Bear and Boo Boo. The years have not been kind to them.
    • In "Irwin Gets A Clue", while Hoss Delgado drives his monster truck, he runs over Yogi, Boo Boo, Huckleberry Hound, Snagglepuss, and Secret Squirrel.
    • The Codename: Kids Next Door crossover episode, which was not only a crossover of KND and this show, but of every one of CN's original shows (that weren't created after its release). At least one character from each show appears in the episode, even one from Squirrel Boy.
    • Mandy even appears in the Foster's Home for Imaginary Friends episode "The Big Picture". She was there as part of a montage of people returning imaginary friends to Foster's in Bloo's speculation of what happened on the year where no one was present in the annual group picture. The one that she was returning was deemed "too happy."
    • The Great Grape Ape appeared as a giant monster on "Giant Billy and Mandy All Out Attack."
  • Crossover Punchline: "My Fair Mandy" ends with the main trio turning into The Powerpuff Girls, with Irwin as Mojo Jojo.
    • "Dream Date" ended with the punchline that the whole short was actually Wilt's dream.
  • Cry Cute: In The Movie, while she doesn't outright cry, Mandy gets teary-eyed at the possibility that Billy might actually have been killed by a Kraken. Of course, she goes right back to normal once Billy shows up alive and well.
  • Cursed Item: In one episode, Grim summons up a suit of armor for Billy to wear, but forgets to mention that the armor is cursed. Billy finds this out when he attempts to go to the bathroom only to be unable to take the armor off. The only way to remove the armor is to win a challenge.
  • Cut Apart: In "Secret Snake Club."
  • Dance Off: The episode "Billy Idiot" features a ballet dance off between Billy's dad and Ms. Pollywinkle the Witch Ballet Teacher. It gets parodied quickly as they start switching up dancing styles, such as the Hawaiian Hula and That Russian Squat Dance.
  • Darker and Edgier: The early seasons were significantly much darker and morbid in tone. After which, the later seasons were particularly toned down and emphasizing more on comedy, surrealism and toilet humor.
  • Dawn Attack: Mandy puts on an army helmet and says "We attack at dawn" in the show intro.
  • A Day in the Limelight:
    • The finale movie starring the side characters, Underfist. Billy, Mandy, and Grim only made some cameos while Fred Fredburger, Irwin, and Hoss are the actual heroes.
    • Mindy gets one in "The Wrongest Yard".
  • Dead All Along: An odd example. In the episode "Who Killed Who," it's implied that Mrs. Doolin is either a ghost or somehow immortal. By her own admission, she beat Grim in "everything"; Mandy realizes that this means Mrs. Doolin beat death itself.
  • Deadly Book: In "Big Trouble in Billy's Basement", Billy reads Grim's copy of The Bad Book against his warnings and becomes a demonic servant of Yog Sawhaw.
  • Deadpan Snarker: Mandy definitely makes a lot of sarcastic comments throughout the series. Grim has his moments, too.
  • Dean Bitterman: Dean Toadblatt, specifically against Weaselthorpe House, and especially against Nigel Planter. Extra points for being voiced by the original Dean—actor John Vernon—in a parody of his role in Animal House.
  • Death and the Maiden: In "Grim In Love", Grim falls in love with a Goth woman named Malaria. She shares his sadistic sense of humor and they both enjoy each other's company. By the end, he reveals to her that he is the real Grim Reaper and that all of his friends are actual monsters, leading her to run away in sheer terror.
  • Death by Cameo: In "The Halls of Time," Billy accidentally drops show creator, Maxwell Atoms', hourglass of life, causing him to poof out of existence immediately after coming up with his "best idea ever" (a fat walrus).
  • Death by De-aging: In "Halls Of Time", Billy and Irwin end up putting theirs, Mandy and Grim's hourglasses upside down. They end up becoming younger and younger until they vanish.
  • Death's Hourglass: Parodied when Grim, Billy, Irwin, and Mandy entered a sanctuary filled with the hourglasses of every human being on Earth. Not only do Billy and Irwin flip theirs and Mandy's hourglass, resulting in their lives instead moving backwards until the point where they don't exist anymore, but they even flipped Grim's hourglass too (odd considering Grim's hourglass was enormous.) They also break at least one, causing that person (the show's creator) to blip out of existence.
    Irwin: Whose hourglass was that?
    Billy: Eh, probably no one special.
    • We also see Jeff the Spider’s in "Jeffy’s Web". Grim actually adds more sand to it to prolong his life… but he did it mostly for his own amusement at Billy’s expense.
      Mandy: You stopped Jeff from kicking the bucket. That’s awfully nice of you…
      Grim: Well, I don’t care much for spiders… but I do love to see Billy wet his pants in sheer terror!
  • The Death of Death: In "Night of the Living Grim", Grim ends up becoming sick with Encroaching Doom Syndrome, so he is brought to the doctors in the underworld. However, they are unable to save him, and he ends up passing away... in that he is now a living human being.
  • Denser and Wackier: The show becomes more and more bizarre as it goes along, with several plots involving some reeeeaaally out there concepts. From season 3 onward, Mandy and her evil schemes get pushed away from the spotlight and more focus is given to Billy's wacky adventures, and the occasional episode would focus on Grim or a side character.
  • Derailed Fairy Tale: "Nursery Crimes" starts the kids in the story of Hansel and Gretel, but they wander off and encounter characters from other fairy tales such as Pinocchio, who wants to Become a Real Boy by eating the flesh of a real boy.
  • Detention Episode: "Detention X" has Grim becoming a substitute teacher and sending the class, Billy and Mandy included, into the Detention Dimension.
  • Detonation Moon: In the alien invasion episode, which ends with the aliens teleporting the dummies from all 5 CN shows involved in the "Invaded" arc.
  • Deus ex Machina: Grim, but more specifically, his scythe, which can do anything.
    • Perhaps the biggest example is from the KND crossover; with the Bone of Barnacles, which was supposed to be a torture device used on Numbuh 1 to get information out of him, but was later used to give Numbuh 1 a giant mecha sized suit of Bone Armor to fight the Delightful Reaper.
    • Two humorous examples occur in "Billy's Growth Spurt." When Billy eats too much junk food, Mandy and Grim try to cook up Grim's granny's famous healing recipe to heal him. The key ingredient is "screaming meemies"; to get them, Grim remarks that an interdimensional rift would have to open in the kitchen. A few seconds later, one does. At the end of the episode, Granny's remedy doesn't work; Mandy wonders aloud if the remedy has an antidote, and Granny quite literally appears in a thought bubble and passes her a bottle of "Heebie-Jeebie Juice," which wraps everything up.
  • Devil in Plain Sight: Mandy is quite blatantly evil, but no one ever suspects a thing.
  • Dhampyr: Irwin is Dracula's grandson, although he's more 1/4 vampire, 1/2 mummy, and 22/7 nerd.
  • Did You Just Flip Off Cthulhu?: In "Crushed", Mandy’s new crush Piff actually had the balls to spit in Grim’s face.
  • Did You Just Punch Out Cthulhu?:
    • Seen literally in "The Prank Call of Cthulhu", where Billy, Mandy, and Irwin succeed in trapping Cthulhu in limbo.
    • The whole show is about two kids who basically enslaved The Grim Reaper.
  • Disproportionate Retribution: In "Super Zero", Captain Heifer from the Heifer Farms Yogurt commercial vaporizes villains with his laser vision just for interrupting him and also threatens to use his laser vision on the audience if they don't buy the yogurt he is advertising.
  • The Ditz: Billy is incredibly stupid. For instance, when shown flash cards of basic addition in "Smarten Up", he somehow thought that "President Lincoln" and "a butterfly" are acceptable answers.
  • Does This Remind You of Anything?: This exchange in "Big Boogey Adventure" between Boogey and Creeper, after Boogey fails to scare Creeper.
    Boogey: Aw, would it kill you to fake it just once?
    Creeper: (sarcastically) It'll make the time when you really scare me all the more special.
  • The Dog Was the Mastermind: Parodied at the end of "Circus of Fear," where it's revealed that Dr. Fear was actually an earthworm in disguise. There's absolutely no build-up to this moment, but Grim and Mandy act as though it was somehow obvious. And treat Billy (and the viewers by extension) as a moron for admitting he didn't see it coming.
  • Don't Fear the Reaper: Grim tries his darndest to be scary, but at his most badass, the guy's still an incompetent wuss. The way he became the Grim Reaper involved a pretty awesome display as revenge for ruining his friendship with his best friend. So he's somewhat weak-willed... unless you manage to REALLY piss him off.
  • Double Entendre: Billy once visited Uncle Chokey the chicken juggler. Which is possibly a Shout-Out to Rocko's Modern Life.
  • Double-Meaning Title: The title refers to not only Grim being one of the main characters, but also the copious amounts of Black Comedy.
  • Downer Ending: A whole lot of the episodes leave the main characters, often along with the rest of the world dead, eaten, horribly transformed or in some surreal dead-end. The lack of any continuity was the one thing that kept the punch-line from being a gut-punch as well. For example, Wrath of the Spider Queen ends with Velma taking over the world with her spider people despite rekindling her friendship with Grim. This part can be chalked up to the show's usual Snap Back, but an even straighter example happens during the credits. It seems like Billy has finally made peace with his son, Jeff, only to go back to his abusive ways when he rediscovers his son is a spider.
  • Dragons Versus Knights: In "Dumb-Dumbs and Dragons", Billy goes back in time to the Middle Ages to learn how to be brave, and becomes an apprentice to a knight who tells him that, as a rite of passage, all knights must slay a dragon.
  • Dumbass Has a Point:

  • Early Installment Weirdness:
    • The first season had a completely different title card theme. The second season would establish the title card theme the rest of the series used.
    • A Running Gag in later seasons is that Mandy never smiles... except she has in early episodes as seen under Perpetual Frowner. Also, the Grim & Evil-era episodes were much darker in tone.
    • In "Trepanation of the Skull and You", the original short film starring Billy and Mandy that Maxwell Atoms made in college, the two characters are very different from how they ended up being in the series. Billy doesn't seem to be as dim-witted, Mandy has a radically different design and is far more chipper than her final characterization as an intimidating jerk, and both of them are taller and lankier.
    Grim: Those people didn't even look like us!
  • Easter Egg: There was once an actual site online mirroring the Secret Snake Club's 1-page shrine to their god Shnissugah (which consisted of an animation of the deity in question slithering back and forth, "dancing" if clicked on, a message saying they would "pwn the cool kids," and some fake ads).
  • Eating the Enemy: You can play a Drinking Game out of how often characters eat each other in this show. And in many cases, they come back later like nothing ever happened. Some notable instances:
    • In the early episode, It's Hokeymon, Billy has Grim bring their Mon cards to life and they predictably cause utter chaos. To put an end to it, Mandy has Grim make a Hokeymon out of a card she made which fires Transformation Rays that turn whatever they hit into toast. Once the all the monsters are turned into toast, they're then disposed of by pigeons.
    • In the special episode, Wrath of the Spider Queen, Velma Queen, who was an old friend of Grim's from school, unleashed her spider army onto Endsville with the goal of world domination. And to top it off, she intended to devour Grim's head to take his title of reaper from him after he apparently cheated to get the title. However, at the climax of the movie, after Grim reveals that it was a big misunderstanding, she drops her plan to eat him.
    • In Underfist, Billy gives Hoss Delgado a weapon called the Candy Blaster that he states is able to One-Hit Kill any single piece of candy. Near the end of the movie, Irwin and Hoss find themselves locked in a combat with a massive monster comprised of all the mutated chocolate monsters from before. Seeing no better moment, Hoss decides to use the Candy Blaster on the monster...which turns out to be Billy...who then proceeds to devour the entire beast and winds up with a big Balloon Belly to boot.
  • Eldritch Abomination: Nergal Jr's true form is apparently horrific. Cthulhu's also showed up, and Yog Sothoth almost did. Also, Mandy. (At least to her antagonists, and quite literally when she assumes an immortal slug form in the future, allowing her to conquer Earth.)
    • The ending of "Scary Poppins" where she is able to MIND CONTROL EVERY SINGLE CHARACTER FROM THE SHOW to scare the nanny away more or less confirms it — Mandy is a Thing That Should Not Be.
  • Elemental Plane: One of several D&D references involved Grim trying to take Billy and Mandy to the elemental plane of fire.
  • Elves vs. Dwarves: "Here Thar Be Dwarves" was a whole episode devoted to the subject, with the enmity between them happening because the dwarves were jealous of the elves running the business of cookie production while they were stuck harvesting mushrooms.
  • End-of-Series Awareness: Two of them in the final, sixth season.
    • In "Everything Breaks", Lord Pain tells Billy that it's about time he visited, to which Billy replied "I'll say. The show's almost over!"
    • In the "Wrath of the Spder Queen" special, Billy brings the Grim Reaper to class, to which Ms. Butterbean tells him "The Grim Reaper was pretty cool the first five or six times you brought it to class, but the magic's sorta worn off."
  • Enfant Terrible: Mandy is a young girl and tends to be cruel and mean-sprited on her best days, and a outright world-conquering villain at her worst.
  • Even Evil Has Standards: Mandy may support any and every legitimate attempt at revenge, dreams of ruling the world as a dystopian dictator, and doesn't flinch at any of the hellish Eldritch Abominations we see throughout the show. But she does NOT condone cheating.
  • Evil Is Not a Toy + Be Careful What You Wish For: Thromnambular, a wishing skull who always grants wishes at a terrible price (voiced by Dwight Schultz, no less).
  • Evil vs. Evil: Most conflicts in the show are between bad and worse characters, seeing as most monsters have to deal with Mandy's cruelty, if not Grim and Billy's as well. The most frequent example is the enmity between Mandy and Mindy and even in the game there is a mode named liked this, which features four of the characters fighting each other (Mandy and Junior with Eris and Boogey).
  • Expy: The eponymous characters are simply human (and gender-bended, in Mandy's case) forms of Ren and Stimpy. They even copied the nose.
  • Extreme Omnivore: Billy will eat anything, even if it isn't edible. He once apparently confused steak sauce with dog feces.
  • Eye on a Stalk: The creepy Brain-Eating Meteor has one long eystalk, which functions as a throat when his eye briefly splits open as a mouth.
  • Eye Scream:
    • Subverted in "Recipe for Disaster" when a woman pepper sprays Grim, only for him to point out that it doesn't affect him because he has no eyes.
    • In "My Peeps", Billy ruins his eyesight by staring at the sun for far longer than anyone in real life can before going blind. His eyes actually turn into frying eggs, then dissipate, leaving behind holes in his head. When Grim fixes Billy's sight, he ends up getting visions of people getting injured that are destined to come true. When Grim tries to fix it again at the end of the episode, Billy's eyes are replaced with live-action eyes.
    • In the episode "Complete and Utter Chaos", Billy is poked in the eye by the Apple of Discord (which had sprouted mechanical spider legs) in his sleep.
    • "Substitute Creature" has a scene where Mandy hands Irwin a telescope, then punches him while he's looking through it and forces it into his eye socket, causing him to scream and say that he can't see.
    • In "Fear and Loathing in Endsville", when Grim and Dracula decide to cook and eat the scorpions that were chasing them earlier, their giant mother appears. Dracula says that he wouldn't have eaten her babies if they weren't so delicious, followed by her stabbing him in the eye with her stinger.
    • In "Prank Call of Cthulhu", Grim gives Billy an ominous speech to deter him from using the Phone of Cthulhu, but when he's done Billy informs him that his Fireball Eyeballs are still lit. Grim asks for something to put it out, but Billy makes it worse by giving him a pitcher of coffee, a bottle of hot sauce, a barrel of acid, and a container of rocket fuel.
  • Facial Horror: Billy's face getting ripped or blown off is a running gag.
  • Fade Around the Eyes: In one scene of "Billy and Mandy's Jacked-up Halloween", Jack o' Lantern leers at the screen ominously as it fades to black around him. An interesting example in that, because he has a jack o' lantern for a head, both his eyes and his mouth light upnote . The weird part is, his eyes always glow, but his mouth doesn't except in this scene.
  • Family-Unfriendly Death: All too common in the early episodes, characters would suffer grisly deaths that most children's shows do not have the stomach to depict.
  • Fantastic Racism:
    • Hoss Delgado's prejudice against monsters comes off as this, since he often attacks every supernatural being he encounters regardless of whether or not they're doing anything wrong.
    • In "Billy & Mandy Save Christmas" Mandy has a prejudice against vampires for some reason.
  • Fear Song: Played with. Billy sings "Scary-O" to list all of the things he is supposedly not scared of, but the song's lyrics consist of a series of paradoxes that invalidate his claims and make it clear he is actually terrified of everything he is saying.
    Billy: "I'm not scared of earthquakes, as long as the ground doesn't shake!"
  • Five-Man Band: Underfist.
  • Flanderization: Mandy, believe it or not. Earlier in the show, she was very witty and snarky, but by no means intimidating enough to order her own parents (or anyone else other than Grim, Billy, and Irwin) around. She also had a rare smirk or two in the early episodes before becoming a complete Perpetual Frowner whose smile could bring about The End of the World as We Know It. She was probably more of an Anti-Hero in some of those earlier episodes rather than the more consistent Nominal Hero later on.
    • Billy's stupidity and other negative traits are significantly cranked up as the series progresses.
  • Flat-Earth Atheist: Mandy doesn't believe in Santa Claus or the Tooth Fairy even though they are shown to exist in this show's universe.
  • Fluffy the Terrible: Mandy's innocuous-sounding name belies how cruel she really is.
  • Forgotten Fallen Friend: In Nergal Jr.'s origin episode, he paralyzes a boy who was disgusted by his appearance and shapeshifts into his form, doing the same to all other children he meets who refuse to be his friend (as an homage to John Carpenter's The Thing (1982)). In future episodes, this boy's form is Nergal Jr.'s "default". The other children were rescued by Billy and Mandy, but Nergal Jr.'s initial victim is never mentioned or seen again... and this episode takes place in bitterly cold weather.
  • Foreshadowing: In Wrath of the Spider Queen during a flashback when Boogey cheats during the Reaper election, he states the only way someone could win the election fairly after the ballot is stuffed is if everyone remaining voted for that person. It turns out this is actually how Grim won. He stopped Boogey from cheating then replaced all the voting ballots with ones that had Velma's name on them instead. When Velma thought he rigged it for himself, he chased Boogey down and did a terrifying performance in front of the whole school, so everyone who hadn't voted yet voted for him instead of Velma or Boogey.
    • At the beginning of the flashback in the same episode, after Grim comments on how scary Velma is when she wants to be, she chalks it up to “pent-up rage”. She then motivates Grim by telling him that he has it as well, and that he just needs to figure out how to harness it. Turns out all he needed was a scythe.
  • Four-Temperament Ensemble: Billy (Sanguine), Mandy (Choleric), Grim (Melancholic) and Irwin (Phlegmatic).
  • The Fourth Wall Will Not Protect You: Several of the brief segments at the beginning of every episode of Mandy talking to the viewer have her make sinister threats toward them.
    • After Nergal ends up transforming everyone in Endsville into beings like him in "Something Stupid This Way Comes", he then transforms the viewer while saying that they'll be his closest, most bestest friend of all.
    • At the end of "A Grim Prophecy", the cave witch tells the audience that she's foreseen their future as well and cackles evilly after revealing that said future is an eternity of commercials.
    • The episode "Duck", features a ghostly, well, duck blowing raspberries by unfortunate bystanders, making it seem like their farting. At the end of the episode, Grim and Mandy are lounging at home when they hear the duck going at it again. At that point, both were already visited by the duck, so it couldn't have been by either of them. Cue Irwin's Grandmama facing the viewer saying, "Oh baby, that is just nasty!"
    • The end of "Everything Breaks" has Billy and Lord Pain deciding to wreck everything in sight. As Billy runs after his friends and family with his mace, Lord Pain uses his to literally break the fourth wall.
    • The short "Fit to be Tied" has Billy demanding a bunny to tie his shoes. Instead, the bunny decides to attack Billy. As Billy runs from even more bunnies coming to maul him, one of the bunnies stops in front of the viewer to blast them with its laser vision.
  • Fratbro: In "Attack of the Clowns", while Mandy and Grim are trying to help Billy conquer his fear of clowns, Billy goes to his happy place in his mind where he encounter his imaginary "Inner Frat Boy" who helps Billy conquer his turning it into hatred for anyone different than him.
  • The Freelance Shame Squad: Grim meets up with his old schoolmate, The Boogeyman, and is not happy about it. When asked why, we flashback to their school days, where Boogey gave Grim a giant wedgie in front of the whole school. Right before they all laugh at him, one monster says "Let's all point and laugh at his humiliation!"
  • Friendly Neighborhood Spider: Jeff, a Giant Spider who is friendly and kind and thinks Billy is his father. Billy, on the other hand, is dreadfully afraid of spiders, and always tries to swat him whenever he appears.
  • The "Fun" in "Funeral": One of the flashbacks in Grim's narration of Jack O'Lantern's past in "Billy and Mandy's Jacked-Up Halloween" shows Jack O'Lantern putting a whoopie cushion into an open grave just before the coffin is lowered in, resulting in the mourners barely restraining themselves from laughing after the subsequent flatulent noise.
  • Fun with Acronyms: In the self-defense seminar Hoss Delgado gives to the senior citizen monsters in "Senior Power", Hoss' advised technique is spelled out as Power, Offense, Obstruction, and Protection.
  • Future Badass: In the Dune parody "Mandy the Merciless" in which Future Mandy rules the world, Irwin (or a descendant) is the huge, muscular leader of La Résistance.
  • Garrulous Growth: In "Billy's Growth Spurt", Billy gets a sentient growth he calls "Yop-Yop" (from the sound it makes) as a side effect of one of Grim's family cures for indigestion. Yop-Yop starts growing as Billy feeds it junk food, and it eventually turns into a homonculous-like miniature Billy and jumps off Billy's back. Mandy gets rid of it by tricking it into drinking another of Grim's home remedies, causing it to dissolve into pink goo.
  • Gasshole: Billy has a tendency to fart and burp.
  • Getting High on Their Own Supply: Billy sells magical chocolates door to door, but he starts eating his own product and is soon hooked. Being magical chocolates, they eventually turn him into chocolate, at which point he starts eating himself. The dealer, a sailor made of chocolate, admits that this happens every time.
  • Giant Spider: Jeff, is a partial subversion - he's a giant spider, but he's extremely friendly, kind, and only wants his father (Billy) to love him. Billy's arachnophobia makes things very difficult...
  • Girl with Psycho Weapon: When Billy's mom tells you that dinner is ready, you better get your butt to the table. *revs up the chainsaw*
  • Gleeful and Grumpy Pairing: Billy is the optimistic and cheerful one who's often naïve, while Mandy is the devious, mean and grumpy one known for wearing an ironically cutesy wardrobe.
  • Go Mad from the Revelation: In "Opposite Day," Grim spends the entire episode being sucked by Billy and Mandy into doing chores by not understanding the basic concept of the holiday. When he finally uses it against them, they point out that because they said it was Opposite Day, that means it's not, so he did all the work for nothing. Cue Grim babbling his lips and bashing his head with a mallet.
  • Goofy Print Underwear: In "Substitute Creature", when Nergal Jr. as Ms. Butterbean is giving Sperg a wedgie offscreen Billy comments "Sperg's got the same bunny underwear I do!"
  • Gonky Femme: In the episode "Duck!", Grim dreams that he is married to a skull-faced dragon with a lion's mane, high heels, a pearl necklace and an apron. The monster is described as a "beautiful wife" by Grim.
  • Greeting Gesture Confusion: In the episode "Dream Mutt", when Billy meets his dream dog, Wiggy Jiggy Jed, he offers Billy a handshake but Billy gives him a high-five instead.
  • The Grim Reaper: The personification of death happens to be one of the show's main characters. He is called Grim.
  • Gross-Up Close-Up: We quite often see disgustingly detailed close-ups for comedic or horrific effect.
  • Grossout Show: Played for Laughs.
  • Guest-Star Party Member: The main trio is frequently joined on their misadventures by at least one other character. While this role typically falls to Irwin, other characters, recurring or otherwise have also stepped up to fill in as their "fourth musketeer" of sorts.
  • Hair-Raising Hare: In "Wishbones" Pud'n wishes for a pet rabbit. The rabbit repeatedly attempts to kill him, no matter how badly injured it becomes.
  • Hammerspace: Where Hoss Delgado keeps his various hand attachments (they're normally seen shifting into place from somewhere inside his arm).
  • Hanging Up on the Grim Reaper: The premise is that Grim came for the soul of a pet hamster, and was accidentally stopped by precocious kids Billy and Mandy. Billy is so dumb and Mandy is so dark that they can't be intimidated by the Reaper, and they win Grim's service after beating him at limbo over the hamster.
  • Head in a Vise: In "Spidermandy".
    Harold: Hey, Billy-boy. How was school?
    Billy: Not good. I feel like I spent the whole day with a clamp on my head. I need a nap.
    Gladice: Should we tell him that he does have a clamp on his head?
    Harold: Now where's the FUN IN THAT?!
  • Helicopter Blender: "Herbicidal Maniac" has General Skarr escape his lawnmower exploding underneath him relatively unscathed, only to fly into the air and through a helicopter's blades:
    "Phew. It's funny, I had this foreboding feeling I was going to be accidentally mulched. Hm. AHHHH!!!"
  • Hell Has New Management: There's an episode where the three main characters have nightmares. Billy and even Grim are both terrorized by their dreams, but in Mandy's dream she actually takes over Hell and becomes the Lord of Darkness.
  • Heroic BSoD: Happens a few times. Mandy nearly has one when, in the Big Boogie Adventure, Billy is dragged underwater by the Kraken and doesn't seem to surface. She instantly comes to her senses when Billy finally resurfaces.
  • Hoist by His Own Petard: Grim is only trapped into being Billy and Mandy's best friend forever because he arrogantly added the stipulation to the limbo contest for Mr. Snuggles' soul. Had he just kept his mouth shut, he would have lost Mr. Snuggles and nothing else.
  • Hollywood Mirage: Implied in "Fear and Loathing in Endsville", where Dracula at one point claims to find a limo. We don't see anything from his point of view, but the limo he finds turns out to be a cactus.
    Dracula: The limo hurts Dracula's butt!
  • Honesty Aesop: In "Hog Wild", Billy, rather than facing a punishment for wrecking his dad's motorcycle, uses Grim's scythe to fix it, ends up turns his parents and many others into biker monsters. The only way everything can co back to normal is if Billy confesses his lie.
  • Horrifying the Horror:
    • Even Grim is often disturbed by some of the things Billy & Mandy do, especially Mandy. It's all but stated that he holds to his bet to be their friend all because he's afraid of what Mandy would do to him otherwise.
    • Eris, goddess of chaos, once tried to enlist Billy to help spread discord - by the end of it Billy had proven to be so inpenatrably stupid & chaotic that he drove her insane.
  • Humanoid Abomination:
    • Nergal Jr takes on a human appearance but is still the son of a dark supernatural being.
    • In "Scary Poppins", Mandy is seen to be one as well, controlling everybody in Endsville.
  • Humiliation Conga: Boogie gets this to absolutely insane levels after Grim takes Horror's hand from him. A rock falls off the ceiling and lands on him, the ground he's standing on breaks and said rock falls on him again, the ground breaks again and the rock follows, he gets thrown into the ceiling by the giant squid from earlier in the episode, again, along with the rock, he lands (but not before getting attacked by a swarm of bats on the way down) and gets crushed by the rock, which breaks, only for a bus to come out of nowhere and send him flying into his ship, which tilts and sends him hurtling into a cannon, which fires him through his ship and into a wall, sinking it.
    • A much less obvious example would be the whole movie for Mandy herself. Not only did she get dragged into the same misadventures as the rest of the group, but she was tortured with horrible nightmares for hours, got kissed by Irwin against her will, had to face her worst fears and ran away screaming, then got beaten up by bears and as if all this was not bad enough it turns out that she did not even win this time and didn't get to own Horror's Hand.
  • Hypercompetent Sidekick: Grim is stuck playing second banana to Billy and Mandy and is frequently the most rational of the group.
  • Hypocritical Humor: During the Underfist special.
    General Skarr: Wait a minute, I'm not a monster.
    Hoss Delgado: No, but I don't trust one-eyed weirdoes either.

  • I'm a Humanitarian:
    • The series' version of Pinocchio believes that the only way he can become a real boy is if he eats the flesh of a real boy.
    • In "Which Came First", Sperg eats Pud'n's arms and legs after they get stranded in the desert together, though that becomes part of the show's Negative Continuity.
    • "Tastes Like Chicken" is all about Billy jumping to the conclusion that Mandy is a cannibal who's eaten his friends and family and plans to eat him next, which ends with a played-for-laughs implication that she actually has eaten Irwin.
    • Eris is shown eating Hoss Delgado several times when she gets mad in "Chaos Theory", though she always uses her powers to spit him out/restore him afterwards.
  • Implausible Deniability: In "Runaway Pants", Billy attempts to run down the street only to become exhausted taking a short leap forward. When Mandy tells him that he's out of shape, he's quick to deny it.
  • Incompetent Guard Animal: One of the dogs that would eventually fused into Wiggy-Jiggy Jed (full-named Sir William Wexell Wingding Whizzlebang the Third) in the episode "Dream Mutt" is Trigger, who wound up being put up for adoption because she did nothing to stop burglars from breaking into her owner's home and then escaping.
  • Introductory Opening Credits: Grim, Billy, and Mandy are each introduced with their name to the side and scenes of them from the show in the background.
  • I Ate WHAT?!: Grim's cookies. For those who don't know, Aunt Kali's secret ingredients are dung beetles, nightcrawlers, and mashed crickets.
  • I Fell for Hours: During Mandy's interpretation of Humpty Dumpty in "Nursery Crimes" with Billy as the main character.
  • I'd Tell You, but Then I'd Have to Kill You: In "Big Boogey Adventure", Billy asks his future self what he is going to have for lunch on Thursday. His future self replies with the trope name.
  • I Got a Rock: In "Grim or Gregory," Billy gets a rock. And promptly eats it.
  • Invisible Jerkass: The titular spectral duck in "Duck!" that latches onto people who become the only ones who can see it. The only sound it ever makes is Blowing a Raspberry, which everyone else interprets as the host farting.
  • I Taste Delicious: Provides the page image. In one episode, Billy is changed into pure chocolate, and can't stop eating himself.
  • Interspecies Romance: Nergal and Aunt Sis's marriage is never presented as anything other than a mutually loving relationship. (But they did have a rather Creepy Child together.)
  • Jackass Genie: Zig-zagged with the wishing skull, Thromnambular. In a few cases, he twists wishes around (Mindy wishes to be a "big star," and he straps her to a rocket; Pudd'n wishes for a bunny rabbit, so he conjures up a psychotic one). However, the majority of the wishes going bad are actually the fault of the wisher—Harold wants to relive his glory days in high school, but they were actually horrible; Sperg wants to be a girl so he can rob other girls in the school bathroom, but fails to account for bitches like Mindy; and Irwin wants to be in a music video with Mandy, ignoring that she hates him.
  • Jailed One After Another: In "Duck!", this happens to Grim, Irwin, and several others when a ghostly duck (whom only its chosen victims can see) gets them in trouble by blowing raspberries and making it look like they're farting at the worst possible moment.
    Grim: At the rate this duck is getting people into trouble, I predict this cell will be full in about... four hours.
    (two hours later)
    Grim: Man, he's workin' fast!
  • Jerkass: Mandy is a very cruel and spiteful girl who often bullies and intimidates Billy, Grim, and anyone else who gets her cross. One of her meanest actions would be in "Grim or Gregory?", where she takes a child's Halloween candy for no good reason and twists the knife by claiming not to care when Billy admonishes her for making the kid cry.
    • Took a Level in Jerkass: While she wasn't the nicest character in the show, she was nowhere near as domineering and flat-out evil in earlier seasons as she became later on.
  • Jerk with a Heart of Jerk / Jerk with a Heart of Gold: Sperg. He constantly shifts between the two, even in the first episode he appeared in. He kicks the crud out of Billy, gets scared off by Mandy, gets cheered up by Billy, and wedgies Billy before the iris in. All in one episode. In the episode where he and the rest of the cast fight off aliens, he gets a bomb planted in his skull that explodes in a day's time...all while Billy whomps the other aliens mercilessly. What does Sperg do? Make his way to the control room, where he eventually detonates, blasting the alien ship out of the sky.
  • Judicial Wig: Judge Roy Spleen wears a curly white wig, which serves his role as The Comically Serious.
  • "Kick Me" Prank: When Grim narrates about Jack, you see Jack using this prank on various people in the animated montage.
  • Kick the Dog: Grim and Mandy have had a number of potential moments, usually involving leaving Billy to a Cool and Unusual Punishment.
    • Billy, though a good kid, has tried to kill his "adopted" son just because he's afraid of spiders.
    • Irwin has allowed a Pyramid to be built in his honor, regardless of whether or not everybody remains brainwashed.
    • Nergal forces a number of people, including the viewer, into transforming into his "Friends" in the second episode he appears in.
    • Boogey does it all the time but one stands out in Wrath of the Spider Queen. During the contest for who would become the future Grim Reaper, Velma was close to winning, but Boogey decided to rig the voting. When Velma finds out, she thinks Grim tried to cheat, costing him his only friend.
    • Ms. Butterbean in "Substitute Creature" when she ignored Sperg bullying Junior because he bribed her with an apple. The drawer filled with apples makes clear that this has happened lots of times. To really twist the knife, she tells Junior that it's okay for Sperg to do it because he was bigger. You don't feel bad when Junior glues her to the ceiling and takes her form.
    • Mindy has had her fair share of moments from attempting to incinerate Mandy for taking her place as cheerleader of the team to beating up Billy with knuckles for being a loser. And let's not even mention Underfist...
    • Sperg lives by being his usual abusive self but he went even beyond it by resorting to cannibalism and eating Pud'n's arms and legs.
  • Kill 'Em All: The episode "Wishbones". 9 characters have their wishes granted. Not many of them survive. Though retconned when Grim wishes Billy and Mandy never found the skull, undoing the wishes.
  • Killer Rabbit:
    • Pud'n's wish for a pet bunny in "Wishbones" gives him this.
    • In "Dumb Luck", Billy pulls a four-leaf clover out of the ground and with it a sizable chunk of where it was growing. He ends up disturbing a colony of prairie dogs, whom Mandy claims kill more people each year than great white sharks. After attacking Billy once, the prairie dogs attack him again when he opens his drawer in his Humiliation Conga montage.
  • Lampshade Hanging: In one episode, people are sucked through telephones and into an alternate dimension, leaving behind their shoes. Mandy asks why the shoes were left behind and Grim comments, "Of course they got left behind, shoes can't fit through a telephone, they're way too big."
    • Half of the show is one big lampshade hung up like a giant pinata.
    • At the end of "Super Zero", Billy asks Grim if he could be changed back from a superhero to a normal boy. Grim, frustrated, yells:
      Grim: Normal?! There's nothing normal around here!
  • Lighter and Softer: The post Grim & Evil episodes, especially in the last three seasons, are much less morbid and frightening most of the time. Characters introduced in this era are the least bit threatening, with Dracula being Redd Foxx instead of the traditional Romanian bloodsucker and Fred Fredburger being a harmless Cloudcuckoolander who relies on Running Gags and Toilet Humour.
  • Lightning Can Do Anything
  • Little Miss Snarker: Mandy could be the Trope Maker.
  • Limited Wardrobe: As is the case with many other cartoons, everyone wears the same clothes all the time.
  • Made of Explodium: In "Everything Breaks" Billy complains that his bowl of cereal isn't pancakes and throws it out the window, and due entirely to Rule of Funny it explodes.
  • Malaproper: A Running Gag in Big Boogey Adventure is that Billybot and Mandroid regularly conflate the word "assimilate" with "annihilate". Their actions generally indicate that they seek to do the latter.
  • Mark of the Beast: Parodied in "Tricycle of Terror" where it turns out that an underworld company actually uses the mark of the beast as its trademark for a catalogue of cursed products.
  • The Meaning of Life: Grim tests a talking computer's knowledge by asking it the meaning of life. It responds that, "Life has no meaning. Only machine intelligence is truly important on a cosmic scale." Grim's surprised that it got it right.
  • Medium Awareness: In the comic book story "Future Tense," Grim says he can use his scythe to decipher what Nostradamus is talking about, which Mandy considers too convenient.
    Mandy: Doesn't this comic have any standards?
    • In "Spider's Little Daddy", when Grim complains about a game where he's playing as a Giant Spider, the muscular human protagonist mocks him and shoots the score under Grim's character, reducing it to 0.
  • "Metaphor" Is My Middle Name: The episode "Scary Poppins" gives us this exchange.
    Billy: Be careful, Grim!
    Grim: "Careful" is my middle name. Oh, I never forgave Mom for that one.
  • Mid-Battle Tea Break: A subversion. When Grim, Billy, Mandy, and Irwin are racing against Boogie and his crew for possession of Horror's Hand, part of the race itself is a stop for lunch at noon.
  • Mid-Life Crisis Car: Discussed.
  • Misery Builds Character: In "Duck!", Mandy is immune to the ghostly duck's attempts to embarrass her since she's friends with Billy, whose disgusting antics are so much worse than the duck's simple raspberry blowing that she considers its act insulting in how pathetically weak it is.
  • Mistaken for Pedophile: In "Duck!" Grim is seen trying to show children he can't be the one making fart noises by showing them his skeleton body and his lack of organs while shouting "Look at my body!". He is arrested shortly afterward.
  • Mr. Seahorse: Jeff ends up laying eggs even though he is a male spider.
  • Mooning: In "Billy and Mandy's Jacked-Up Halloween", Billy is asked by Mandy to distract Jack while she prepares to take on Jack's pumpkin army with an arsenal of pranks. Billy distracts Jack by mooning him.
  • Mohs Scale of Violence Hardness: Level 5. Frequent on-screen death and violence, most frequently to children, gruesome slapstick, internal body parts and organs are frequently shown and sometimes ripped out, and there's a Running Gag of Billy getting his face torn off. Not to mention that, being a Gross-Out Show, there's quite a lot of Squick-inducing imagery. It's generally Bloodless Carnage, though, and the extremely zany, wacky tone takes some of the edge off of even the nastiest scenes.
  • Mrs. Claus: Who is a vampire.
  • Multi-Character Title (if you count "Grim" as being one of three character names in the title)
  • Multiple-Choice Past: The origins of Grim and his profession vary from time to time, should the plot of the episode call for it.
  • Musical Episode: "Little Rock of Horrors" was a Shout-Out to Little Shop of Horrors, with original music by Voltaire.
  • My God, What Have I Done?: Subverted with Mandy in the episode "A Dumb Wish", when she accidentally wishes everyone on Earth away into oblivion ...but then she gives a devilish smirk and goes home to watch TV.
  • My Little Phony: Grim's favorite show "My Troubled Pony", combining colorful ponies with an over-the-top Soap Opera. Unfortunately for him, it was Cut Short.

  • Name and Name (Grim and Evil, Billy and Mandy)
  • Negative Continuity: An odd example - despite many episodes ending with some sort of bizarre or apocalyptic Downer Ending that can only be resolved via Snap Back (such as the main characters dying, being erased from existence, or given a permanent Baleful Polymorph, everyone on earth becoming descendents of Billy, the entire universe imploding and turning into The Powerpuff Girls...) continuity nods and call backs are fairly common, and the status quo does occasionally shift around. Gets especially odd when the acknowledgement of a past episode coincides with the aforementioned Snap Back, as happened with the episodes that introduced Nergal Jr, the entire underworld court system, and Hoss Delgato and Eris's short lived relationship.
  • Never Say "Die": Unsurprisingly given the premise, this is usually averted, but not always consistently - there's quite a few times where they clearly have to dance around it by using substitutes like "destroy".
    • Also we have a tidbit where Grim says "Billy, what were you trying to do? Scare me to me?"
  • Never Trust a Hair Tonic: Billy tries some hair tonic and ends up growing hair all over his body looking like a sasquatch. It turns out that all he has to do to get rid of it is wash it off.
  • Next Stall Shenanigans: In "Substitute Teacher", Billy tries to flush a skeleton model down the toilet, screaming louder and louder as he gets increasingly frustrated. Pud'n, who is in a nearby stall, listens to everything with a worried expression on his face, which turns into sheer horror when one of the fake bones slides into his stall.
  • Nice, Mean, and In-Between: The main trio, mostly in early seasons. Happy-go-lucky Billy is the nice one (mostly because Dumb Is Good, but he has his Jerkass moments too); Mandy is a devious, cold-hearted Villain Protagonist; and surprisingly Grim mediates between the two, despite being the Grim Reaper, he's not nearly as evil as Mandy.
  • No Celebrities Were Harmed:
    • Principal Goodvibes is most likely based on Paul Lynde.
    • Dracula is a dead-on impression of Redd Foxx of Sanford and Son, right down to calling people "dummy". There may also be a bit of Mr. T in there as well.
  • No Fourth Wall: The show quite frequently breaks the fourth wall and has characters indicate that they're aware they are in a television show.
  • Nonindicative Name:
    • "The Incredible Shrinking Mandy" is actually about Billy attempting to shrink Mandy but accidentally making her giant.
    • "Billy's Growth Spurt" even has a Nonindicative Title Slide depicting Billy as a middle-aged hick, when in fact the episode revolved around a growth on his back that eventually detached and turned into a miniature version of Billy (affectionately named "Yop-Yop" by Billy himself for the sound it makes).
  • Non Sequitur, *Thud*: Billy's first appearance in Underfist includes this.
  • Noodle Incident: Several of the people stated by Boogie to have stolen Grim's scythe in Billy and Mandy's Big Boogie Adventure (including a girl scout troop, the Sleestaks from Land of the Lost, and a turkey salad sandwich) were not shown stealing it in the show, leading one to speculate what may have happened during these incidents.
  • No Periods, Period: Averted in "Mommy Fearest", where Billy states that his mom "is grappling with the onset of menopause."
  • Not Even Bothering with an Excuse: Combined with Rule of Three to make a minor Running Gag in one of the Nigel Planter-centric episodes; whenever Nigel starts singing and playing with a puppet, two characters make up excuses to leave, while the third doesn't bother justifying themselves.
    Grim: I, uh... I have to meet somebody.
    Billy: I left the oven on.
    Mandy: You're weird.
  • No-Holds-Barred Beatdown : In the episode "Short TALL Tales" General Skar threatens to sue Mandy (who's interpreting Paul Bunyan) Mandy answers him by tattling her to her lawyer Beck (Who's a giant humanoid cow), said lawyer spends the entire night beating the crap out of Skar
  • Nothing Exciting Ever Happens Here: Endsville. Justified in that a town where Death resides is bound to be a weirdness magnet.
  • Not This One, That One: Billy and Pud'n entered a pie eating contest and Billy ate all the pies he saw at a table. However, those were Pud'n's pies. Pud'n was declared the winner.
  • Not Where They Thought: At the start of "Billy and Mandy Save Christmas", a very frantic Billy is in a long line. He assumes it's the line to the men's room, but a kid in front of him informs him that it's the line to see Santa Claus.
  • The Nudifier: General Skarr's "Atomic Hot Pants Raygun". Well, it doesn't cause his clothes to disappear, just change, but, still.
  • Ode to Food: "Little Rock of Horrors" has the "brain-eating meteor" singing about eating brains and manipulating Billy into bringing the townspeople to him so he can eat their brains.
  • Off-Model: Nergal and Nergal Juniors' teeth sometimes switch from jagged to flat and back again when they're talking.
  • Offscreen Reality Warp: In "Modern Primitives" after Billy has thawed Fred Flintstone out:
    Billy: Now, don't destroy the house while I'm gone.
    (Fred is standing in the living room)
    Billy: (sticks his head out from the kitchen) Do you like chili on your cereal?
    (living room is destroyed, Fred is in the same position he was when Billy left)
    Billy: Eh, never mind.
  • Oh, Crap!: Jack O'Lantern displays this expression when it appears that the knight who killed him (really Irwin in a knight costume) has returned to finish the job.
  • Once More, with Clarity!: The Reveal in "Wrath of the Spider Queen". We once again see the flashback when Velma believes she caught Grim cheating to win the Reaper Election. But this time, after she knocks away the bucket, we see a close up of the ballots Grim was putting in; every single one had her name on it.
  • Opening Shout-Out: Big Boogey Adventure has a scene where Mandy keeps waking up from horrible nightmares. One of the places she wakes up in is a black void, where most of her Couch Gags at the end of the theme song take place.
  • Opposite Day: A short in the first episode, as reckoned once the Evil Con Carne shorts were removed.
  • Our Werewolves Are Different: In one episode, Irwin gets bitten by a werewolf and transforms later that same night (whereas they typically only transform during the next full moon), not by looking at a full moon, but by looking at a butt on a billboard (apparently mooning is enough). After he transforms, he remains like that into the daylight hours of the next day and acts like a gentle dog instead of a werewolf.
    • I'll take the chicken.
    • Also, the flashback when Billy wants to go on a picnic.
  • Perpetual Frowner: Mandy.
    • If she does smile, the very fabric of reality is pulled apart. A Moment of Funny ensues.
    • Also a result of Flanderization since in the Grim & Evil shorts and some episodes of earlier seasons did show her smiling more. Not a whole lot more, but not to "must never smile" extremes.
    • Bit of Fridge Logic perhaps, but in previous instances of Mandy smiling, she had a reason. In the pageant, her smiling without cause broke the rules.
    • Whenever she smiles and nothing bad happens, something bad's already happened, and she was merely pleased with the — often unsettling — results.
  • Physical God: Eris.
  • Playing Pictionary: Dracula's Pictionary drawing of Abraham Lincoln is mistaken for successively more absurd things.
  • Poor Communication Kills: Played for Laughs in "King Tooten Pooten". The episode ends with Irwin deciding to finish building the pyramid like his grandfather, King Poppin Lockin, wanted… but he didn’t realize that the pyramid would become his tomb because Poppin Lockin failed to mention that until the last minute.
  • Popular Is Dumb: Mindy, definitely.
    Mindy: But as beautiful and popular as I am, I bet there are some people who've never even heard of me: people in countries like Paris or Toronto, or in cities like Africa.
  • Portal Pool: One episode featured Grim's sythe reflecting sun light on to Billy's pool. Naturally, everyone jumps in.
  • Potty Emergency: The episode "Terror of the Black Knight" is all about this. Billy wants a badass knight costume just like Irwin, so Grim gives him one, but unfortunately, Billy drank too much punch that he has to use the bathroom, and he can't get the knight armor off unless he wins a challenge with someone. He then wins a breakdancing contest against Mandy, but as soon as he gets his armor off, he doesn't have to use the bathroom anymore. You can also hear splashing sounds during the breakdance scene.
    Mandy: So, aren't you gonna rush over to the boys' room?
    Billy: You know the funny thing? I don't need to go anymore.
    [Billy walks off]
    Mandy: Ew.
    • In the Christmas special, Billy mistakes the Mall Santa line for the line to the bathroom. "I feel like my bladder's gonna explode!" After rattling off his long Christmas list to Santa Skarr, the latter asks him "Have you been relieving yourself on me this whole time?"
    • Also happens in the episode "Tricycle of Terror", after Billy drinks too much lemonade.
  • Power Trio: Mandy (evil), Billy (stupid), Grim (hapless)
  • Pragmatic Villainy: In "The Grim Adventures of the Kids Next Door", Mandy and the Delightful Reaper get into a Giant Mecha style fight. Once Grim and Numbuh One get on the scene, she allows herself to be assimilated so she can join the winning team, and also seems to totally take over the Delightful Reaper's Hive Mind in the process.
  • Precision F-Strike: In Billy and Mandy's Big Boogey Adventure, Skarr at one point yells "Damn".
  • Production Throwback: The film grain effect during the title sequence hides this, but the gravestones are inscribed with the names of three fellow series (Evil Con Carne, Time Squad, and Whatever Happened to... Robot Jones?), all of which were cancelled during the production of the show's first solo season.
  • Properly Paranoid: Gladys, Billy's mom. She has every right to be paranoid of Billy hanging out with the Grim reaper, considering he reaps souls and all.
  • Pumpkin Person: Jack, a trickster who was decapitated. After a deal with Grim (Returning his scythe in exchange for immortality), Grim cut off his head. He then replaced it with a Jack-O' Lantern.
  • Pun: During the Christmas Episode, Grim and Mandy are busting into the lair of a vampire, coming to a locked door, which does nothing to deter Grim. Mandy asks how they expect to get through, to which he replies "A skeleton key!" He is then pelted with a snowball.
    • In "The Firebird Sweet", Mandy asks what type of cereal box comes with a phoenix. Grim looks at the box and says, "Well, this cereal came from Arizona." In other words, Phoenix, Arizona. (except we see it came from "Eris-zona" - a place owned by the Goddess of Chaos, Eris.
  • Punctuated! For! Emphasis!:
  • Pun With Pi: In the episode "Test of Time", Billy is reading a book on theoretical physics and when he gets to a formula with pi in it, he goes to get pie from the fridge.
  • Put on a Bus: Billy's Mom goes away to live with her sister in the first episode of the main series but comes back in the same season. (Which, for strange scheduling reasons, was 11 months later.)
  • Rage Breaking Point: In "A Kick in the Asgard", when the Viking that Billy replaced when he went to Asgard takes his place at home, Harold claims that he was fine with the Viking being rude, destroying furniture, running up phone bills, shaving Milkshakes and harassing Gladys, but he won't tolerate the Viking cutting off the front of his hair (which is where his brain is stored).
    • In the flashbacks during "Wrath of the Spider Queen", Grim has to put up with a lot, especially from Boogey… but it’s Boogey indirectly ruining his friendship with Velma during the Reaper Election that finally sends him over the edge.
  • Ragtag Bunch of Misfits: Underfist in a nutshell- a spectral exterminator, a hybrid mummy-vampire-nerd, an ex-paramilitary officer, a giant talking spider, and a little elephant-demon creature, all of whom find themselves working together to put an end to an invasion of demonic candy.
  • Raised by Wolves: Pud'n was raised by wolves. Funnily, said wolves are seen watching TV in his backyard after he reveals this.
    • According to Mandy's parents, a band of wolves stole her away shortly after she was born to invoke this trope. They're both still unsure if getting her back was really for the best.
  • The Real Spoofbusters: According to Grim in "Billy & Mandy Begins", this is how the title characters became friends, with Billy donning a proton pack and brown jumpsuit and catching Grim in a trap.
  • Relax-o-Vision: In "Here There Be Dwarves", a drill sergeant (voiced by R. Lee Ermey, no less) pops up to explain they'll be showing a cute koala instead of the overly-violent battle between the dwarves and the elves.
  • Reminder of Impossibility: When Billy and his dad enter a metal competition, Billy's dad decides to make a flashy entrance by flying onto the stage. However, the moment Billy says "I didn't know you could fly," his dad immediately realizes what Billy is saying and falls.
  • Repeated Cue, Tardy Response: In season 6 "Goodbling and the Hip-hop-opotamus", when the school announcer tries to introduce Principal Goodbling:
    School Announcer: Attention. Attention. Introducing... Principal Goodbling!
    (A spotlight appears at his office door.)
    School Announcer: Uh... Principal Goodbling! (beat) I said...
    Goodbling: Girl! I dun heard you the first time! The stupid door is stuck again! Someone get me out of here!
  • Reverse Cerebus Syndrome: The early episodes are a lot darker and morbid in tone. After a few episodes, the series hit its stride and evolved into the wacky, nonsensical show it's known as.
  • Retcon: Grim's origins have been fairly inconsistent throughout the series. In "A Grim Prophesy", his parents teach and instruct him to be the reaper as a child, and make him reap during the stone age. In the episode where he explains why his father loves country rock more than him, the flashback shows that he just stumbles upon the reaper scythe while walking along a street, contradicting the other episode. The Spider Queen special shows that he gains the role of Reaper through some underworld middle school class election, where he must prove he is capable of getting said role.
  • Retraux: One episode had the trio wind up in a world made to homage the black and white cartoons from The Golden Age of Animation. Too bad Mandy puts a stop to it, since she despises retro cartoons.
  • Ridiculously Cute Critter: Milkshakes, Billy's pink cat.
  • Right on Queue: The episode "The House of Tomorrow" has a seemingly short line for a rollercoaster, but it turns out that's the line you have to wait in to get in line for the rollercoaster. And apparently, somebody died in the line and a baby was born in it.
  • Road Sign Reversal
    Dean Toadblatt: Hey, jerkwad, you're going the wrong way! The Enchanted Meadow is in that spooky cave, and the deadly Manticore is in that happy meadow! Can't you read?
  • Robot Me: Billybot and Mandroid in the first movie are robot versions of Billy and Mandy sent back from the future.
  • Rogues Gallery Transplant: General Skarr was a Villain Protagonist working for Hector Con Carne in ‘Evil Con Carne’. However, the show’s early cancellation lead to Skarr moving into Endsville and becoming a minor enemy to Billy and Grim instead.
  • RPG Episode: Grim's idea of breaking Billy and Irwin's video game addiction, didn't work as intended.

  • Sadist Show: What else can you call a show where the Grim Reaper is the nicest of the main characters?
  • Sanity Slippage: Happens quite a few times, but one of the most notable is when Mindy loses her cheerleader position. This stirs up the B plot of the respective episode, making Mindy attempt to hinder, incapacitate, and even kill Mandy to get her position back.
  • Sassy Black Woman: Irwin's Grandmama, Tanya.
  • Saving Christmas: "Billy & Mandy Save Christmas"
  • Scare Dare: An abandoned house. It's just some old lady living alone. Well, OK, she is also a ghost.
  • School Clubs Are Serious Business: There was an episode where the students joined school clubs. Mandy joined the Secret Snake Club, who believes in a snake-god that will eat all of the cool kids. Billy joined the Secret Service club, and discovers the knitting club is being used as a criminal front.
  • The Scottish Trope (saying "Lord Moldybutt")
    • Hilariously enough, not even Lord Moldybutt himself is immune to this.
  • Seadog Peg Leg: Parodied in the episode "Billy Ocean" with Captain Deadwood, a Captain Ahab Expy who had replaced his entire body with wood.
  • Sealed Evil in a Can: Some episodes deal with evil or dangerous beings being released from their imprisonment, frequently but not always because of Billy's stupidity.
    • "Aren't You Chupacabra to See Me?" had Billy buy an underworld videotape containing a chupacabra that would be freed from the video to feed on blood once the video was played.
    • "Pandora's Lunch Box" played with the legend of Pandora's box and had Pandora trick Mandy into opening her lunch box to unleash all the chaos and evil sealed within it. In the end, Mandy reseals the malevolent spirits back into the box along with Pandora.
    • "The Show That Dare Not Speak Its Name" had Billy scramble an enchanted puzzle cube, setting free a Captain Ersatz of Pinhead called Pinface.
    • In Wrath of the Spider Queen, Jeff's anger is revealed to be caused from being possessed by Arachnotaur, the Spider God of Anger, who was imprisoned in a carton of chocolate milk until Billy freed him by opening the carton.
  • Second Person Attack:
    • "Chicken Ball Z" begins with Mandy repeatedly punching Billy in the face at a karate dojo, portrayed this way.
    • Towards the end of the episode "Sister Grim", the giant nun (formed by many regular sized nuns) sends Grim home with a big punch after they find out that he wasn't actually a nun the whole time.
    • At the end of the episode "Hoss Delgado: Spectral Exterminator", Hoss fights a werewolf. They jump up, and the camera pans, Matrix-style, to (almost) the POV of the werewolf. Hoss fires his slime gun at the werewolf, filling the screen to a fade-to-black.
  • Series Continuity Error: The series tends to have loose continuity, but one particularly glaring continuity error is in "Waking Nightmare", where a gag involves Grim farting as he sits down and initially thinking the noise to be a whoopie cushion, when the earlier episode "Duck!" had Grim make it perfectly clear that he is incapable of flatulence.
  • Severely Specialized Store: One episode shows a store at the mall called Sock Barn, which sells only socks. The reason why the characters were there, however, is because Billy eats socks.
  • Shipper on Deck: Grim has teasingly shipped Billy and Mandy on occasion.
    • He refers to Mandy as Billy’s girlfriend in the episode “Opposite Day”. Billy is quick to respond She Is Not My Girlfriend.
    • In "Love is Evol Spelled Backwards”, he makes a paper doll chain of two, one with Billy’s name written on it, and the other Mandy’s.
    • In “Which Came First?”, after Billy’s been taken by giant mutant chickens…
      Grim: That’s it. We’re outta here!
      Mandy: Unfortunately, we can’t leave him.
      Grim: Awwwww. I knew you two were sweethearts. (makes kissy noises)
    • In "The Bubble with Billy", he tries to get Mandy to flirt with Billy to get him to cough up the supernatural gum he swallowed.
  • Ship Tease: The topic of Billy and Mandy getting married seems to come up often. In one episode, he even kissed her.
    • When Mandy finds out that Billy fell in love with a seemingly normal girl. Cue a shocked expression, a slightly saddened expression, then a total verbal beatdown of how desperate the girl is. If it were anyone else other than Mandy, one would call her jealous.
    • Whenever Irwin tries to kiss her or woo her she either gags and literally throws up or gets angry and punches him. When it is suggested in one episode that Mandy use her feminine wiles on Billy, she's not really that against it and she didn't gag or throw-up. In fact, she moaned and got a little annoyed but compared to her normally extreme reactions-especially when Irwin is involved-this was nothing.
    • In "The Show That Dare Not Speak Its Name", Pinface at one point refers to Billy as Mandy’s “boyfriend”, and unlike in the episode "Opposite Day" (where Billy was quick to say “She Is Not My Girlfriend”), neither of them outwardly deny it.
  • Shout-Out: Now has its own page.
  • Shot at Dawn: In one of the darkest jokes in the series (which is saying a lot), this is heavily implied to happen to Billy at the end of "Guess What's Coming to Dinner" after he attempts to escape the military school he's been enlisted in.
  • Side-Effects Include...: In "Nergal's Pizza", Nergal tells Jr. to spike Granny Grim's pizza sauce with some "horrible ghastly elixir". When Jr. asks what it does, Nergal responds "I don't know, but it's ghastly."
  • The Singing Mute: King Cobra in the Secret Snake Club never talks on his own. The only time when he ever hear his voice (aside from when he gives out pained grunts when "P.E." is ever mentioned) is when he sings the tale of Shnisissugah with his guitar and harmonica.
  • Sliding Scale of Idealism vs. Cynicism: The show is more cynical than your typical kids show. However, there is a fair amount of idealism still left in this series.
  • Sliding Scale of Realistic vs. Fantastic: Way down on the surreal end, especially later on.
  • Smart Jerk and Nice Moron: Billy is a total idiot who only seems to have hard feelings towards the bully Sperg and his son Jeff (who is a spider). His best friend Mandy, however, is a straight-A (or rather, "A+++++++") student, who hates just about everyone else, and finds the idea of having a crush on someone to be repulsive.
  • Snap Back: With gusto. A good third of the episodes end with characters dead.
  • Soap Within a Show: Grim's favorite show My Troubled Pony.
  • Sociopathic Hero: Mandy and Grim.
  • Speak of the Devil: Lord Moldybutt. If you say his name, something breaks nearby, whether it be a tree falling, or a door knob falling out. It doesn't matter who's affected by it, (because once, a tree falls on him) it will happen.
  • Spider People: The title character of the episode "The Wrath of the Spider Queen", Velma Green.
  • Spiritual Successor: To The Ren & Stimpy Show, right down to copying both characters (Gender not necessarily withstanding.)
  • Spoof Aesop: In one episode dealing with Billy's fear of clowns, he learns from his inner frat boy that just because someone is different from you, doesn't mean you should be afraid of them. Instead, you should be angry at them! How dare they be different!
  • Spotting the Thread: When Nergal Jr. tries to impersonate Mandy he screws it up by smiling, something she would never do, and Billy picks up on it immediately. No one seems to notice that Mandy suddenly got glasses for no apparent reason, though.
  • Squashed Flat: In Billy and Mandy's Big Boogey Adventure, the villains' boat gets flattened vertically in one scene, and then falls over on its side.
  • The Stinger: Scenes playing over the credits became increasingly common (to the point of eventually being true for every episode) as the series went on. Usually they were just a Deleted Scene or What If? scenario, but occasionally they did conclude the plot of one of the previous segments.
  • Stellification: In "Wishbones", Mindy finds the magical wishing skull and wishes to be a star, famous and renowned worldwide. She ends up tied onto a rocket, shot into space, and blown up like a normal star as part of the Jerkass Genie nature of the skull's wishes.
    Thromnambular the Wishing Skull: I'll make you the biggest star of all! But the bigger they are, the harder they fall!
  • Sudden Anatomy: In one early episode, Mandy spontaneously grows nostrils when Billy picks her nose. Later on, however, her not having a nose is actually a plot point.
    • Grim is a more Egregious example: Being a Skeleton and all he's not supposed to have any functionality despite being able to move and funcition like any normal human right down to seeing without eyes, on occasion he will make comedy of his inability to smell or feel in some episodes but on others is quite reactive to bodily harm and the show's grossout humor.
  • Suddenly Fluent in Gibberish: In Underfist, Irwin pleads with Hoss, Skarr, and Jeff that, among other things, Mindy was kidnapped by a marshmallow bunny. However, his hysterical Inelegant Blubbering couldn't be understood by anyone save Jeff, who speaks "crybaby."
  • Super Window Jump: Played with.
  • Swiss Army Appendage: Hoss Delgado's prosthetic hand. It's typically a metal hand, chainsaw or Arm Cannon. (The video game even refers to it as a "Swiss Army Hand" in Hoss' bio.)
  • Tank Goodness: Hoss owns a giant fist-and-arm shaped one in Underfist, which partially provides the team's name. It bursts out of the ground blaring "La Cucaracha" for its' horn.
  • Tarot Motifs: During the credits. Not named as such, but Billy is clearly The Fool, Mandy The Hierophant, and Grim... well, let's just say he ain't the Wheel Of Fortune.
  • Tastes Like Diabetes: The Happy Huggy Stuffy Bears and Enchanted Forest from "The Crass Unicorn" are In-Universe examples of this trope. They get disgusted reactions from Mandy and Grim.
  • Team Pet: One-shot character "Admiral Wolverine Lightningbolt", an alien whom Billy named because "those are the three coolest words in the universe."
  • Tempting Fate: At the beginning of "Tricycle of Terror", when Billy crashes his bike and comes back to it later he finds that he can still ride it, only for the tree it crashed into to snap and fall on it, then a meteor falls on it and the whole thing gets swallowed by the earth.
  • Territorial Smurfette: One episode featured a tribe of Smurf expies and Grim tried to capture them. One of his attempts consisted on disguising himself as a female of their species, resulting on him getting a beating from their Smurfette.
  • The Ahnold: Hoss Delgado, being a mix between Snake Plisken and Ash Williams. And Lil' Porkchop after he became huge, as he talks with an exagerated accent and his dorsal fin becomes a sort of crew-cut haircut.
  • Thick-Line Animation
  • Third-Person Person: Dracula.
  • Those Two Guys: Grim and Mandy often play this part in the episodes that revolve around Billy.
  • Toilet Humor: Constantly. In "Hog Wild", Billy, fed up with rules, tries to fart on Grim. Instead, he soils his pants.
    • Actually, this is at near-Running Gag level with Billy. You'd be hard-pressed to find an episode without at least one occasion of Billy needing to use the toilet or talking about how he soiled himself. Very common random joke for this show.
  • Toilet Horror: Played for Laughs when Pud'n mistakes Billy disposing a skeleton model in the toilet as a gory incident.
  • Tongue on the Flagpole: Billy gets his tongue frozen to Santa's sleigh in the Christmas Special.
  • Too Dumb to Live: Billy, on a good day.
    • He somehow managed to get -5 in a IQ test.
  • Too Spicy for Yog-Sothoth: Two examples act as joint Trope Namer:
    • "Big Trouble in Billy's Basement". Billy is pulled through a dimensional portal by Yog-Sothoth himself, but thrown back, and Billy explains in dejected tones "They didn't want me", prompting Hoss to say "Well, I guess that makes you a total loser".
    • In "Little Rock of Horrors", a brain-eating meteor-creature first attempts to eat Billy's brain but finds nothing. When it later devours Mandy's brain, it screams in pain, dies, and then reforms—but with Mandy in control. She comments "I guess my brain was a little too... spicy [for him]." Mandy then reuses the exact same gambit in "The Grim Adventures of the Kids Next Door", intentionally, to take control over the Delightful Reaper.
  • Transplant: General Skarr from Evil Con Carne, who's nobly trying to give up a life of world domination for suburban normalcy. He's fond of garden gnomes and cornbread.
    • "Real corn makes it SPECIAL."
  • Tuft of Head Fur: Sassy Cat has fluff on her head.
  • The Ugly Guy's Hot Daughter: Gender inversion, Sperg and his mom.
  • The Un-Reveal: In "My Fair Mandy," the entire episode is spent building up to her having to actually give a genuine, non-malicious smile for the first time in her life. However, when she finally accomplishes it, we only ever see a close up of her mouth stretching upwards, and a distant shot that doesn't give enough detail to clearly see her face in-full. It still doesn't stop the universe from unraveling as a result though.
  • Vague Age: None of the main kids' (Billy, Mandy, Irwin, etc.) exact ages are ever mentioned (though they do appear to be around 10 or 11), and their school seems to be a combination of both elementary school and junior high. Billy mentions repeating the 2nd grade again, but that might have been just a one-off gag.
  • Valley Girl: Eris was portrayed as one in her first appearance. To explain the change regarding her later characterization, Grim mentioned her going through a "Valley Girl phase."
  • Verbal Tic: Irwin, yo!
    • Also, Irwin’s Dad, dude!
    • Fred Fredburger! Yes.
  • Villainous BSoD: In the football episode, Mindy has one when she and her cheerleaders are cast aside by the coach in favor of Mandy, despite Mindy's serious threats against her.
  • Villain Decay: The Grim Reaper, In-Universe.
    Grim: I used to have a chariot of four-hundred burning horses. My arrival on the scene would be a raging thunderclap of fear! Now it's, "Hey, have you seen Grim?" "Yeah, I think he's wedged between a history textbook and a tuna fish sandwich!"
  • Villain Song: Mindy gets one in Underfist.
  • Vignette Episode: "Wishbones" is pretty much an exercise in letting every regular on the show's writing staff do their own mini-sode, with the concept of a Jackass Genie skull being the sole unifying premise.
  • Voluntary Shapeshifting: Nergal's son Nergal Jr. can take on anyone's appearance.
  • Voodoo Shark: This exchange from "Guess What's Coming to Dinner":
    Hoss Delgado: And there I was, Goodacre-
    Principal Goodvibes: It's "Goodvibes"!
    Hoss: ...Surrounded twelve foot zombie poop elves! Nowhere to go but-
    Goodvibes: Excuse me, but, how could they be elves if they were 12 feet tall?
    Hoss: It was a leap year.
  • Waiting Skeleton: In "The House of No Tomorrow", the gang waits on a very long line at an amusement park, and a skeleton (not Grim) is seen as one of the people on line.
  • Was It All a Lie?: Parodied in "Scary Poppins". Being informed that Mandy is not related to him is such a shock to Billy's Dad that it causes him to question whether anything in his life is true, including his real son and his marriage. Granted, Billy's dad is an idiot.
  • "Well Done, Son!" Guy: Jeff the Spider endlessly aims to please no matter how many times the arachnophobic and Too Dumb to Live Billy tries to murder him.
    Jeff: *while repeatedly jabbed in the eye with a large stick* Why won't you love me, Dad? I'll be whatever you want me to be!
    Billy: I want you to be dead!
  • Weirdness Magnet: Anyone and anything associated with Grim.
    • Lampshaded in the crossover with KND; Numbuh 1 states all the weird stuff happening in Endsvile is why the KND prefer to stay away from that area.
  • We Will Meet Again: Numbuh 3 humorously makes a threat as if she were a villain promising revenge in Billy and Mandy's Big Boogey Adventure after Grim gets his job as the Grim Reaper back.
    Numbuh 3: I'll get you for this, Grim, if it's the last thing I do!
  • Wham Line: Grim delivers one in "Dracula Must Die".
    Grim: Irwin's Grandmama is Dracula's wife?!
  • When She Smiles: Two examples are given in "My Fair Mandy". Mandy ends up smiling at the beauty pageant, but it causes reality to be destroyed and her, Grim, and Billy waking up as The Powerpuff Girls. The other example is the underworld makeup specialist Crabina, who is seen smiling when Mandy begins her part of the talent portion of the contest in spite of implying earlier that she is incapable of smiling because of the work done on her face.
  • "Where Are They Now?" Epilogue:
  • Who Wants to Live Forever?: Jack O' Lantern, although in his case it's less "immortality sucks" than it is "immortality having to wear a pumpkin for a head sucks".
    Jack: 364 days a year, I can't even go to the ding-dong grocery store to buy pudding! And do you know why?!
  • Who Writes This Crap?!: Played for Laughs occasionally, where it cues to a monkey or a baby in front of a typewriter.
  • Why Did It Have to Be Snakes?: Billy has severe arachnophobia, which is bad news for Jeff.
    • He also has a fear of clowns and the mailman.
    • Irwin's greatest fears are stand-up comedy and bears. Cue him getting mauled by them very quickly.
    • Mandy's greatest fear is the possibility that she will grow out of being who she is, and actually become nice... and furthermore, marries Irwin.
    Mandy: "I'm glad that's over with." *Gets mauled by the bears*
    • Grim and Billy believe that Mandy is afraid of ice skaters, but Mandy denies it, she just "doesn't trust the way they spin".
    Grim: Like that ice skating thing?
    Mandy: It's not a thing, alright? It's not... a thing!
  • Wild Teen Party: In "The Show That Dare Not Speak Its Name", Pinface invites a bunch of frat house demons and they proceed to wreck Billy's house. Harold, instead of doing literally anything else, joins the monsters in trashing his own house, and when Gladys comes home, she's rightfully mad at him.
  • With Friends Like These...: Grim, Billy and Mandy's supposed "best friend," is normally treated like little more than a slave, and openly mentions on more than one occasion that he often fantasizes about killing them.
  • Wizarding School: Dean Toadblatt's School of Sorcery.
  • What Happened to the Hamster?: Remember how this all started with Billy's hamster? Never heard from again except in flashbacks.
    • There is one episode where it saves Billy's more visible cat Milkshakes from a fire or something, only to be eaten. It breaks free in the end and Billy mugs the camera to announce "Oh, come on, like we'd really do that."
  • Women Are Wiser: Played With - they're much smarter on average than the men, most of whom wouldn't even be able to function in the real world, but they also tend to be either batshit insane or horribly unpleasant.
  • The Worf Effect: Played for laughs. Pretty much any problem in the series could be easily solved with Grim's Reality Warper powers, but something always gets in his way, most often his scythe being stolen/transformed/running out of batteries. Though most of the time, this could be attributed to his own stupidity.
  • World of Weirdness: While a walking, talking skeleton with a scythe would have turned heads at the start of the series, as time went on it becomes host to a wide variety of supernatural hokum that Bystander Syndrome became the common response.
  • Yandere: Nergal Jr. (although a sweet and lonely child) can become so obsessed with making friends that if someone befriends him, he'll do anything to make sure that he is their best friend. Usually, he doesn't realize how angry and jealous he can get.
    • His father was a bit like this himself.
    • The rabbit from "Wishbones".
  • You Can't Fight Fate: In Big Boogey Adventure, the Bad Future version of Billy goes back in time to stop Mandy from taking over Endsville. He succeeds, only to return to the future and see that Fred Fredburger is now in her position.
  • Your Brain Won't Be Much of a Meal: The brain-eating meteor doesn't find anything in Billy's head. Human and Martian zombies also find nothing appetizing in Billy's head.
  • Your Size May Vary: The Squid Hat is the size of a small hat in his debut episode. By his final episode, he's as large as Toadblatt himself.

Skarr in Space

Skarr taunts everyone as his statue rises from the ground, failing to notice as he reaches out of the atmosphere.

How well does it match the trope?
