History Funny / TheGrimAdventuresOfBillyAndMandy

** Billy and Mandy's counterparts in the shadow world. Shadow!Mandy is sweet and obsessed with unicorns, much to Mandy's disgust. Shadow!Billy is [[BeyondTheImpossible even dumber than the real Billy]] and his only means of communication are barking like a seal.

** When Billy and Sperg are in detention Mandy is still there simply because she wanted to watch Sperg get his comeuppance. She shows him her test paper has an [[BeyondTheImpossible A with 6 pluses]].

** Later on Grim's MushroomSamba after succumbing to scorpion venom ([[YouFailBiologyForever even though he has no veins for venom to travel through]]).

** In "Billy & Mandy's Big Boogey Adventure" when Future Billy (from the post apocalyptic Endsville ruled by [[spoiler:Mandy]] and later by [[spoiler:Fred Fredburger]] after he alters the timeline) goes back to the future he blows Billy's face off, after which he states "I like that guy".

** In "Billy & Mandy Save Christmas" when the trio arrive at the North Pole, Billy wanders into a cave with what looks like [[StarWars a wampa and a rebel trooper who is dangling from the ceiling]] and the former rips off his face. When he comes back out he tells Grim and Mandy "Santa has sharp nails".

* Irwin's alter egos in ''The Secret Snake Club'', including Manny the Mauler, Mr. Magic Muttonchops, and Debbie.

-->Grim: "Stop being afraid of clowns! Stop it you ninny! STOP! BEING! AFRAID! OF! CLOWNS!"

* "Substitute Creature" has a scene where Pud'n runs in fear after seeing the skull from a biology skeleton in the toilet (Billy replaced the skeleton with Grim in an effort to cheat his way through a test, a plan which backfired horribly since it was a math test and he told Grim it was history, which is Grim's best subject). He runs straight into a janitor and they both tumble down the stairs. Later on when he sees Nergal Jr. wrapping Ms. Butterbean in his tentacles, he runs into the janitor AGAIN (who now has a cast and bandages) and they fall out the window...which reveals the school is [[FridgeLogic located on a tall mesa overlooking a desert.]]

** When Billy and Sperg are in detention Mandy is still there simply because she wanted to watch Sperg get his comeuppance. She shows him her test paper has an [[BeyondTheImpossible A with 6 or 7 pluses]].

-->'''Boogey''': Is it not true that not only was your scythe stolen by a headless man wearing a pumpkin on his neck, but was also taken by Billy, Mandy, Irwin, Billy's father, Billy's mother, Billy's cousin (Nergal Jr.), Billy's cat, Dracula, General Skarr, Principal Goodvibes, Mrs. Claus, the Secret Snake Club, the Army, Scout Troop 701, the [[LandOfTheLost Sleestaks]], the President, the mailman, the Dingleschmidt sisters, the Boogeyman, a llama, [[ArsonMurderAndJaywalking and a turkey salad sandwich...]] (ominously) hold the mayo?

** Billy meeting and running away from a dishelved YogiBear. The best part is either when Boo-Boo comes out of the bushes revealing that he's now absolutely huge or when Yogi says he knows Billy is close and calls him dirty, to which Billy points out his last bath was over two weeks ago.

** Later on he flushes Porkchop down the toilet, commenting "[[LampshadeHanging I didn't think I'd get him down at first being he was so gigantic and all]]".

* The montage from "Lil' Porkchop" with Billy tending to Porkchop. Naturally Billy doesn't realize he needs water and keeps exposing him to heat, starting by taking him to a playground (on what he says is the hottest day in the history of the world) and putting him in the sandbox, then taking him to a tanning booth which burns him to a golden brown, and finally taking him to a restaurant where after eating the food he yells in pain and falls through the wall, after which he crumbles.

-->Video game guy: [[CrossesTheLineTwice "Now shut up, sissy!"]]

-->Video game guy: [[NoForthWall "What's that bones? You over there crying?]] [[TakeThat Well cry about this!"]]

-->Video game guy: [[BreakingTheForthWall "What's that bones? You over there crying?]] [[TakeThat Well cry about this!"]]

** [[PunctuatedForEmphasis IMPORTANT! COMMERCIAL! MESSAAAAAAGE!]]

** At the beginning Billy has made a huge mess in the kitchen to make one sandwich, one of the ingredients consisting of a pink turtle, which is still alive.

* [[RavesAndCrows Sir Raven]].

** [[ThisIsSPARTA IMPORTANT! COMMERCIAL! MESSAAAAAAGE!]]

--> '''Grim''': Billy's out of control! Somebody do (realizing that Mandy's lack of enthusiasm sums up how both of them should feel) ...some...thing. (to Mandy) You're right. He's gone. Let's go sell his things.

** During Grim's first story in "Short Tall Tales" Billy (as Pecos Bill) gets his face ripped off when battling the tornado.

** In "Billy & Mandy Save Christmas" when the trio arrive at the North Pole, Billy wanders into a cave with what looks like [[StarWars a wampa and a rebel trooper who is dangling from the ceiling]] and it rips off his face. When he comes back out he tells Grim and Mandy "Santa has sharp nails".

(cut to Billy standing on one end of a tennis court, dressed and prepared for a match)
'''Grim (Deadpan):''' Wrong court, dummy.

* "I can spell my name real good. F-R-E-D F-R-E-D-B-U-R...G-E-R. Fred Fredburger! Yes."

** Later on after Jr. has taken on Ms. Butterbean's form he reveals that Billy drew a doodle of a clown with a flamethrower in place of an actual answer. Billy tries to remedy it by [[CompletelyMissingThePoint giving it a pirate hat.]]
