- All of "Operation: E.N.G.L.A.N.D."
- "Operation: L.I.C.E."
- Right before Numbuh 5 is about to destroy the Queen Lice, Numbuh 2 interrupts them and says she needs to deliver a Pre Ass Kicking One Liner
Numbuh 2: WAIT!!! You gotta say something cool first! Like "Say cheese, punk!" or "Cheese to meet you!" Wait, wait, wait! How about this—(Numbuh 5 presses the button as the Queen Lice is distracted) Cheese—(Cut to a scene of the Treehouse and a giant melted cheese explosion)
- Bonus points for Five and the Queen Lice giving each other a "what the heck is wrong with this guy?" look right before Five pushes the button, and Two being covered in baby lice.
- "Operation: S.U.P.P.O.R.T."
- "Operation: F.U.G.I.T.I.V.E."
- What's even funnier is that Numbuh 86 finally gets her comeuppance for antagonizing Sector V for the duration of the episode.
- And right before the grand chewing out, Chad just silently slinks away. He's not gonna help her out of this mess.
- Number 86 spazzing out during the incident with the toenail collection.
- And even before she gets covered in them and completely loses it, we get this gem:
Numbuh 86: (voice wavering) Whu-what's that?
Delightful Children: It's... our toenail collection.
Numbuh 86: Toenails? (gags, sputters, otherwise flips out) That's disgusting!
Delightful Children: It is not! It's more like... a hobby. (laugh evilly as they close in on Numbuh 86)
- As Numbuh 86 goes on a tirade, Numbuh Four whispers to Numbuh Two: "Man, who put a bee in her undies?" Near the end of the episode...
- And then there's Numbuh Four going back for the dandelion.
- During "Operation: E.N.D.", a decommissioned Numbuh 3 is being unhelpful even as the base is floating into the sun.
Numbuh 1: Come on, team. Let's get up to the observation deck.
Numbuh 3: Why should we?
Numbuh 1: Because the sun is very hot. And you don't want to hit it!
- When Numbuh 1 and Numbuh 2 have to leave class for a mission in "Operation: F.O.U.N.T.A.I.N.", they leave behind dummies in their likeness made of fruit. Numbuh 3 just leaves behind a balloon with the word "ME" written on it.
- "Operation: T.R.A.I.N.I.N.G."
- When Father finds the safe containing the Kids Next Door code module at the Arctic training base:
- "Hey, Fireface! Looking for this Code Module thingy?"
- Not to mention that Father finds out it's an autograph book, and is impressed on it having Numbuh 362's autograph.
Numbuh 60: Any questions?
Tommy: Oooh, I have one! I know Numbuh One!
Numbuh 60: (facepalm) That is not a question, Tommy.
Tommy: And Numbuh Two is my brother! I even have all their autographs from when I went on a mission with them!
Numbuh 60: Back in line cadet!
- Every time Father bursts into flames, the ice above him melts and splashes him. Helps to turn that power of his into Nightmare Retardant.
- Two of Father's henchmen threaten to put Tommy, Lee and Sonia into a broom closet. Cue Sonia freaking out and Tommy and Lee shivering in fear as she beats the two guards into submission.
- Number 74.239 playing around with the Voice Changer. "Nigel Uno, I am your father!" And then Numbuh Infinity's reaction as he grabs the voice changer: "Give me that!"
Numbuh Infinity: But enough with the voice changer thing!
Numbuh 74.239: Aw, but it makes me sound so cool!
- Numbuh Four's abysmal spelling in "Operation: R.O.B.B.E.R.S.":
Numbuh Five: I'm telling you — the word "chicken" does not have a "2" in it.
Numbuh Four: Well it does now!
- The reveal of the Ship Tease in the Grand Finale:
Wally: (as Kuki is crying on Hoagie's shoulder) And would you mind hugging your own wife instead of mine?!
Hoagie: Hey! You're not Abby!
- Also, Numbuh One seeing the giant toilet in the Delightful Children's bathroom.
"So that's how they go together!"
- The Empire Strikes Back parody in "Operation: S.N.O.W.I.N.G.". Especially because A) 4th grade President (of Gallagher Elementry) Jimmy plays the part of Darth Vader, and B) they actually find Luke Skywalker.
- The snag in Cree's Evil Plan:
- There was also a Call-Back to this in one issue of the KND comic; Numbuh 86 is partially decommissioned when she turns on one of the machines, goes boy-crazy in the process, and one of her officers questions why the machine would zap the person who turned it on. Another officer responds that the guy who made the "Blow-Up-The-Engines" button on all KND spacecraft worked on this machine, and says they really should get rid of that guy some day.
- Sweet merciful Numbuh Zero, "Operation: S.I.T.T.E.R.". Just... "Operation: S.I.T.T.E.R.". Numbuh Two tries to seduce Cree.
- Made even funnier when you remember that as cheesy as all the bad French he uses sounds to us, it must have been even worse for Cree as she herself is half-French.
Cree: (blankly stares, then facepalm) This is so not worth 8 bucks an hour.
I don't wanna go to bed yet! You can't make me! Cree: Oh, I applaud your braver
— (clapping activates disco ball)
- Operation: Z.E.R.O.
- How about this little exchange?
Numbuh Four: Listen, Numbuh Five... I don't wanna fight you!
Zombified Numbuh Five: Of course you don't! Cause you're the weakest, shortest, dumbest, most chicken, big mouth squirt on the entire team!!
Numbuh Four: (raging) OKAY! NOW I WANNA FIGHT YOU!
Hey Spankaholic! Time to teach you the Australian word for "ouch"! Count Spankulot:
Ridiculousness! Those who fail to realize that the Australian word for "ouch" would still be "ouch" will be—
(Numbuh Four pulls out a gun that SHOOTS A KANGAROO) Spankulot: (beat) Is that a... kangaroo?
- Numbuh One turning into a total fanboy when he realizes that his father used to be the legendary Numbuh Zero.
- After Sector V drops the Moonbase on Grandfather, we see that Father's mansion was destroyed in the explosion as well. Father has this to say about it.
- There's also his "He's Back" moment. After getting the short end of the stick from his father for nearly the whole movie, he finally loses his patience with everything. Only to resign himself to everything that's happened and stroll off to eat some ice cream.
You... big... JERK! Now you've made me angry. VERY. VERY. VERY... ah, forget it.
Numbuh 4: Kuki, I-I'm scared. I don't know what to do next!!
Numbuh 3: Kiss me!
Numbuh 4: Kiss you?! No way! Oh, nonononononono! Nu-uh! Nope, no way! Ain't gonna happ- okay.
- Before Grandfather is defeated by his son and grandson, he shouts this at his son: "You're out of my will, you BRAT!"
- The Rhetorical Question Blunder from both Father and Grandfather's villain meetings- the first one, Father prepares to unveil "The ultimate evil". Toiletnator thinks it's someone who doesn't flush. Count Spankulot thinks it's "shoddy glove manufacturers" (as his gloves are filled with holes). Crazy Old Cat Lady think it's dogs. And various other villains come up with ideas, like "magazines at the doctor's office", before Father silences them. The second time, Grandfather rants about how he has to destroy the Book of KND to prevent the kids from rising up again, as it contains the one thing that could stop him. Mr. Fizz thinks it's a guy with really big fists who can punch really hard. Mr. Boss speculates it's an army of robot gorillas who can bite real hard. Knightbrace thinks "Pie?", to which Mr. Fizz does a Face Palm.
- While they do serve as terrifying most of the time, some of the lines of the Delightful Children from Down the Lane are pretty damn funny.
- For example: "Hello Kids Next Door. Perhaps you would like to try kicking our posteriors now?"
- "A heater? Who puts a heater in an ice cream factory?!"
- When Billy in the crossover episode asks to use their new device as a bathroom, they allow him... before realizing just what he's about to do. Including the flushing. "NO! NOT THAT!"
- Then there's the Little Traitor Dudes for Children's Defense from the Alternate Universe in "Operation: P.O.O.L." and their Totally Radical dialogue.
- In the episode where Numbuh Two turns into a teenager and goes out with Cree, Cree's reaction to finding out she had made out with Numbuh Two was hilarious.
Numbuh Two: (as Cree makes constant spitting noises) Aww come on, it wasn't that bad was it?
- "Operation: B.E.A.C.H."
Numbuh Three: Well, how about you Numbuh Four? Do you wanna be my Prince Charming?
Numbuh Four: And miss being buried in the sand? Fat chance!
- Numbuh Four's repeated reasoning for why he's saving Numbuh Three from having to marry King Sandy: "She just owes me a quarter!!!"
- And then when he saves Numbuh 3 and they're running out, the sand castle crumbling around them...
Numbuh 5: (tied up w/ Numbuh 2) HELOOOOO! AREN'T YOU FORGETTING SOMETHING!?!?
- King Sand's Knights using a catapult to "conquer" Numbuh Three's castle (a tiny sand castle).
- "Operation: S.U.P.P.O.R.T." in its entirety.
- B.R.A. = Battle Ready Armor
- Made all the funnier when Chad shows up with one in "Operation S.L.U.M.B.E.R.".
- In "Operation: D.A.T.E." Lizzie appears as Numbuh One is confronting the Delightful Children:
Nigel Uno, I'd like a word with you! Delightful Children:
What is the meaning of th— Lizzie: SHUT UP!
- "Operation: C.A.T.S."
- As Mr. Boss is about to escape:
Mr. Boss: So long, kid! I hope your friend likes Pluto! (entire building crashes on top of him)
- From "Operation: R.A.B.B.I.T.":
Numbuh Two: (upon seeing the desolate First Grade hallway) Man, those school budget cuts are murder.
- At the end, when returning the Frist Graders pet rabbit restores them...
Numbuh Two: But man, I'm so hungry, it's not even bunny! (Starts to laugh until Numbuh Five smacks him with her hat for making that joke)
Numbuh Five: You did not just say that! That is the worst line Numbuh Five has heard from you yet! (continues ranting as she chases him)
- "Operation: I.T."
- The entire KND is having a worldwide game of tag, with the person who is "it" at the end of the game becoming the next Soopreme Leader. Everyone is trying their hardest to avoid being "it" at the end of the game... right up until someone tags Numbuh Thirteen. Cue the dogpile.
- Bonus points that he was the only operative besides Father excited to get the position.
Numbuh Thirteen: HOT DOG! I'm gonna be the leader of the Kids Next Door!
Operative: OH, NO YOU DON'T! (dogpile)
- The leader of the Jamaican KND sector is happily chilling at the beach when he's approached. He just pulls out his weapon and points without even looking.
"Don't even think about it, mon"
- Numbuh Two tries hiding in low orbit, in a secret spot he uses to read Rainbow Monkey Romance magazines. Unfortunatly, it's not as secret as he thinks it is, as Numbuh Five catches up with him and reveals everyone knows what he gets up to up there.
Numbuh 2: I only read it for the video game ads, I swear!
- Father ends up being Tagged (as part of a plot of his to infest all the KND treehouses with broccoli, and Numbuh 287 and One desperatly try to trick him into declaring another game of Tag so he'll lose his authority. Too bad when he does, 287 freaks out over being Soopreme Leader again and tags the Delightful Children.
287: I DONT WANT TO BE SOOPREME LEADER AGAIN! TAG, YOU'RE IT!
Delightful Children: WE DONT WANT TO BE IN CHARGE OF A BUNCH OF MISBEHAVED BRATS!! TAG, YOU'RE IT!! *tags Father back then run off screaming*
- In "Operation: L.O.V.E.", which musical fans will recognize as a spoof of West Side Story. Let's count the ways:
- '50s' style costumes (including Numbuh One wearing tacky 3D glasses).
- The sheer crackiness of the Delightful Children playing Tony to Numbuh Three's Maria (followed by Numbuh Four's reaction). Whats better is that the Delightful Children, true to form, are playing Tony as a unit, so they share a single costume, and even a kissing scene, which Numbuh Four interupts.
Numbuh Three: I know I'm safe when I look into your, uh, ten eyes?
- The kids dodging lasers by dancing to the tune of "America".
- Numbuh Four singing, in the most deadpan tone ever, a sugary-sweet love song with Numbuh Three and then quitting after a couple of lines.
- Numbuh Two FINALLY getting a funny pun down, which not only wasn't pointed out or made anyone groan, but would probably only make sense to those that watched West Side Story to get the reference: he rips his jacket off to reveal a jetpack and says "When you're a jet, you're a jet."
- While all the explosions are going off, the audience is still watching, completely unaware that it's no longer a play. Cue this lampshading line from Numbuh Two's grandmother:
Numbuh Two's grandmother: I can do without all the fancy-schmancy special effects. What's wrong with just a simple love story?
- "Operation: H.U.G.S."
- How do you stop a giant rampaging Rainbow Monkey? By giving it the "Rainbow Monkey Goodbye Hug". So, who has to deliver this hug? Numbuh Four.
- Immediately afterwards:
Numbuh Four: Well! That takes care of that!
(Numbuh One and Numbuh Two snicker; apparently having witnessed the entire scene)
Numbuh Two: (cooing) Awww... Big bad Numbuh Four gave the monkey a hug!
Numbuh One: Ooh! Can I have a "huggie-wuggie" too, Numbuh Four?!
(they burst into hysterical laughter)
Numbuh Three: (offscreen) Hey!
Numbuh Four: Huh? (looks down and spots Numbuh Three, who had just returned from the Rainbow Monkey Fair)
Numbuh Three: You didn't just call a giant Rainbow Monkey "stupid", did you?
(The giant Rainbow Monkey turns around and lunges angrily at Numbuh Four)
- "Operation: S.P.I.N.A.C.H."
- We have two hilarious things coming in on the same time: The Spinach Inquisition, and Sector V singing lyrics in the style of Green Eggs and Ham.
- Nigel's banter.
Vespinacio: You speak-a the blasphemy-a!
- "Operation: N.A.U.G.H.T.Y.": The secret weapon the elves used to get Numbuh Three to surrender her presents.
- The reveal of Numbuh 86's father. Mr. Boss.
- What's even better is the return of Sonia's fear of the dark. She beats Mr. Boss while the male operatives — including Numbuh One — have to stare at her with absolute horror.
- A car carrier for cruise ships, among other everyday sights in "Operation: I.N.T.E.R.V.I.E.W.S." Even by the show's usual standards, that episode was insane.
- When the episode is titled "Operation: C.L.O.W.N.", hilarity is probably to be expected. Not only does Hoagie get in a decent joke for once ("Knock knock, who's there, not me!"), he then runs away from the clowns determined to never let him be funny again... and into the Big Top, where he proceeds to run over a seesaw, have an elephant fall on the other side so that he gets catapaulted into the grip of a trapese artist, is tossed into a cannon, and is finally fired onto a tight rope. Cut to audience member Abby, wide-eyed and mouth stuffed with popcorn.
- Operation: A.F.L.O.A.T.
You stupid kids, you can't hide in my garage! Wait a minute...
I don't have
a garage! *the garage transforms, revealing a KND vehicle*
- The villains once again tried to ditch Toiletnator by telling him the barbecue was held in Antarctica, but as usual it didnt work.
- "Operation: B.U.T.T."
- The reveal that Numbuh One has a big butt and all the joke puns everybody makes at his expense.
Numbuh Five: (reads mysterious note) "Leave your team behind, or we'll put your behind in the school yearbook?"
Numbuh Four: What does that mean?
Numbuh Five: I have no ide— (eyes widen in shock upon discovering photograph of Numbuh One's backside) Ah— Oh, no. Is that Nigel's hiney?!
Numbuh Two: Wow. That is one big butt!
Numbuh Four: Oh, 'lemme see! (snags photo) Wow-ho-ho-ho-ho! Wah-ha-hoo— WOW! WOWIE!!!
Numbuh Three: Where did they get a camera big enough to capture all that tushie?! (She and Numbuh Four burst out laughing)
Numbuh Five: Come on, guys! This isn't funny! We've got to do something!
Numbuh Two: Yeah! We've got to get to the bottom of this!
(Numbuh Five sighs, while Numbuhs Two, Three and Four laugh harder)
Numbuh Five: Now, come on, guys!
Numbuh Three: (between convulsions of laughter) That is not gonna fit in the yearbook!
Numbuh Two: Unless they put a big section in the rear!
(They crumble into even more laughter)
Numbuh Five: OK, OK, now come on, guys!
Numbuh Two: If I were Numbuh One, I'd just turn the other cheek!
(Numbuh Five scowls at everyone before eventually succumbing to the jokes herself and exploding in hysterics)
- Operation: L.I.C.O.R.I.C.E."
- Number Five challenges Stickybeard to a sugar swallowing contest. When Stickybeard decides to not do so, she replies "Unless you're... sugar-free." Cue all the pirates going "Oooh..."
- That same quote gets an Ironic Echo when it's revealed that Stickybeard was a cabin boy to legendary Black Licorice Pirate Old John. The undead pirate laughs in the face of the challenge so Stickybeard goes, "Unless ye be...sugar-free."
Licorice Pirates: Oooh..."
- Even better, Numbuh Five takes his place in the sugar swallowing contest and ultimately spazzes out. Then, after defeating Black John once and for all, Stickybeard pours some sugar for he and Numbuh Five to partake in. Numbuh Five collapses into a sugar coma.
- How about the fact tha Black John is lauded as unbeatable at sugar swallowing, yet the only reason he's unaffected is because he's just a licorice skeleton in his present state, and the sugar just passes right through his ribcage. This goes unmentioned by the episode itself.
- The pirate shanty about how the licorice pirates were cursed.
And that's when the Licorice, Licorice, turned rancid and black. It was dead, no, not red and tasted like (coughing)
- "Operation: G.R.A.D.U.A.T.E.": We get to see the Delightful Children turned into sheep. Sheep that look like the one in Sheep in the Big City, no less! (Mo Willem, one of the main storyboard artists for KND, created the show).
- "Operation: Q.U.I.E.T."
- Numbuh Five tells everyone not to do anything that will wake Numbuh One up. They all silently agree, then walk quietly over to the sofa, then Numbuh Two turns on the TV...
Announcer: MONSTER TRUCK RALLY! DO YOU LIKE MONSTER TRUCKS? LOUD MONSTER TRUCKS? THE LOUDEST MONSTER TRUCKS THIS SIDE OF LOUDSVILLE!
- Made even funnier by the fact that Numbuh Two loses the remote the second the TV comes on.
- In the episode's final shot, all the characters involved were sleeping together in a big pile... including the villains!
- This bit from "Operation: P.I.A.N.O.", after Numbuh Four botches the mission to destroy the Type-P torture device:
Numbuh One: Okay, Kids Next Door. Simple question. What did we learn today?
Numbuh Two: Do not deviate from plans.
Numbuh Five: Teamwork is the key to mission success.
Numbuh Three: Operational procedures are important.
Numbuh Four: (in a wheelchair and covered in bandages) Pianos...are heavy.
Numbuh One: Oh, close enough.
- The KND manage to destroy all the pianos before Numbuh Four screwed it up...except for the very piano that was meant for him.
- Operation S.C.I.E.N.C.E.:
- "CRAZY 80'S 2X4 SUPER-STORE!" is a barrelful of laughs (Fart ID spray, the Jelly-O-Matic spraying the scientists with bean residue ("Twenty percent of the time, still working out the kinks out on that one...), and the Teacher-Canceling Headphones.
- Father is without a doubt one of the Kids Next Door's most dangerous foes. With his fire powers, he's a Person of Mass Destruction...unless he goes off around something that reacts to intense heat, like popcorn (M.U.N.C.H.I.E.S.) or ice (.T.R.A.I.N.I.N.G.) or cake frosting (C.A.K.E.D-.F.I.V.E.). Then, Hilarity Ensues.
- In the flashback beginning of Operation: M.A.U.R.I.C.E., Numbuh 9, the titular Maurice, is making a passionate vow to find the Teenz' source of Chicken Pox when his mother comes in with cookies for him and the Kids Next Door.
Numbuh 9: Mooom! I'm in the middle of a life-defining speech here!
- The Creative Closing Credits used in the 4th season onward, showing a little sketch while the credits run, are always good for a laugh in some episodes.
- After C.L.U.E.S., Numbuh 2's grandma Lydia is going through the fridge, looking for something to eat while grumbling; "What am I craving? A man with a job. Haha, I crack myself up...!"
- From the earlier episode F.U.T.U.R.E., the credits featured Madame Margaret destroying her Girlifyer Ray... synchronized to the ending theme song.
- After D.I.A.P.E.R, Numbuh Five tells the others where babies come from, and we're privy to their reactions:
Numbuh One: (completely and utterly speechless, mouth hanging open)
(same reaction, until he starts gagging
, falling out of his chair in the process)
Numbuh Four: (same as 1 + 2, except his face/hair have been blasted backward)
Numbuh Five: (nodding in seriousness)
...wait a second! That's preposterous! Babies don't come from New Jersey!
They come from Philadelphia.
- In Operation: M.O.O.N., Sector V raises a picture of an earthrise to fool Numbuh 4's family living on the fake moon. Across North America in big yellow letters is 'FREE HAMBURGERS'.
- Operation: C.L.U.E.S has Hoagie solving the mystery of who stabbed Kuki's Posh Party Rainbow Monkey during a dinner between the Carmichaels and Sanbans. When it comes time for the dramatic reconstruction of the crime, which Kuki's sister Mushi committed, the episode inexplicably switches to live-action, where a large man who's dressed in a shirt that says "MUSHI" and a pair of pigtails does some wonderfully hammy acting as he hugs the Posh Party Rainbow Monkey. The genre shift, coupled with the sheer ridiculousness of a giant man playing a little girl, makes it a wonderful Big-Lipped Alligator Moment.
- There's also Mr. Sanban's furious reactions to Kuki and Mushi "fighting" over the Posh Party Rainbow Monkey...except they're not fighting at all, but being extremely kind and agreeable about it.
- This hilarious exchange between Hoagie and Tommy:
Hoagie: You're hiding something. SPILL IT!
(Tommy nervously takes out an empty soda can and a wrapper from his pocket)
Hoagie: Hey... this was my candy and soda, you rotten stinker, you stole this from my room!
Tommy: I-I'm sorry, Hoagie...
(Hoagie grabs Tommy by his cape)
Hoagie: Why'd ya do it, Tommy?
Tommy: I...I was...thirsty- no, no, no! I was hungry...
Hoagie: That fish is three days old and I ain't buying it!
Kani: Now, look here boy-
Hoagie: SIT DOWN! (Kani sits down reluctantly) Sing, Tommy!
: I was thirsty-(gets slapped
)-I mean hungry-(gets slapped again
)-I mean thirsty-(slap
Hoagie: I want the truth!
Tommy: I WAS HUNGRY AND THIRSTY!!!
(everyone gasps in shock
- Even better when you realize it's a reference to a scene from Chinatown of all things.
- Around the time the ARG site for Galactic Kids Next Door went up, the video for the ARG was uploaded by Morbidcrab. A few days later, the site was updated, and entering Morbidcrab gives this gem:
- Operation V.I.R.U.S:
- Numbuh 2's diorama, and Numbuh 4's reaction
'That's the same diarrhea thingy you made for history class!
- "Stop the g:KND", when Numbers 3 + 4 find out Lizzie is an alien:
(stunned shock) Holy- (beep)
Number 4: (under his breath, a little scared) She looked better as a plant-
Lizzie: I HEARD THAT!
- The Stinger of The Grim Adventures of Billy & Mandy Crossover shows a couple posters promoting five fake crossover specials called "Ed, Edd, N' Mandy", "Evil Camp Carne", "Class of Numbuh 3000", "My Gym Partner's A Mandark" and "Samurai Mac".
- In Operation T.A.P.I.O.C.A, Numbuh Two is ambushed by the Senior Citizen Squad the leader of whom is his grandmother, when their aging cream starts to wear off and they retreat before the others arrive. Numbuh Two tells the others what happened, they don't believe him, thinking he's making up stories. The next day...
Numbuh 2: You guys gotta believe me! I was attacked by that gang of superpowered teenagers last night! Honest! I swear, I was!
Numbuh 4: Oh, yeah? If you want us to believe you, you're gonna have to give us proof!
(suddenly, the Senior Citizen Squad storms in, breaking the door down)
SCS Leader: Teenagers, ATTACK!!!
Numbuh 4: (meekly) You know what? I believe you...
