* Anytime when Mac is having a sugar rush. Especially in ''Partying is Such Sweet Soiree''.
-->'''Mac:''' [[Music/DefLeppard Pour some sugar on Mac!!!]]
* Try watching [[EnsembleDarkhorse Cheese's]] first episode with a straight face. It's impossible.
** "''Hot rod flames!''" "''Bunnies!!''" They eventually compromise on [[BreadEggsBreadedEggs flaming bunnies]].
-->'''Bloo:''' I don't even know you anymore.\\
'''Mac:''' Shut up. At least the bunnies are on fire.
** The fact that the music for when Cheese screams is just banging randomly on a toy piano.
** Cheese's conversation with Eduardo.
-->'''Cheese:''' I like cereal.
-->'''Eduardo:''' I like potatoes.
-->''(Repeat ad nauseum)''
* At the start of "Busted", Bloo is suffering from a PottyEmergency, and Mr. Herriman won't let him go unless he makes his bed and brushes his teeth. It's cruel and hilarious at the same time.
-->'''Herriman:''' (''after Bloo uses too much toothpaste'') Pea-sized...\\
'''Bloo:''' Don't say "pee", please.
** After trying (and failing) to fix the broken bust using toothpaste, Bloo remarks [[DoubleEntendre "A bust this big needs ample support!"]]
* All of the viral video parodies in "World Wide Wabbit." Yes, including- nay, ''especially'' the one with the dubbed-in farts.
* "Frankie My Dear":
** Prince Charming's introdution, where he drops enough cheesy pick-up lines to give [[Creator/WillSmith The Fresh Prince]] a run for his money.
--> '''Bloo:''' Oh, no! He's using ''lines!''
--> '''Prince Charming:''' Is it hot in here...or is it just you?
--> '''Pizza Guy:''' Good ones!
** [[TotemPoleTrench ORLANDO BLOO.]] The part where he's trying to eat the steak is the funniest thing to ever come out of Foster's.
-->"Oh, silly me. A spoon can't '''pick up a steak!'''"
** Let's also not forget how Frankie and "Orlando" dated for 20 years.
--> '''Dylan''': How old did you say you were?
--> '''Frankie''': I'm ''22''.
--> '''Dylan''': So that means you guys have been dating since you were...
--> '''"Orlando"''': [[WritersCannotDoMath 47]], yes. I mean, 2.
** How did "Orlando" and Frankie meet? Apparently, at a pep rally at Billionaire School.
--> '''"Orlando"''': So then after the pep rally, I went up to her and said, "Hey, babe, I'm a [[EleventyZillion gazillionaire]]."
** Bloo's "putting aside our differences" speech to Mac, and then with the delivery boy, and finally with Prince Charming. He always adds "especially not Mac".
-->'''Bloo:''' Especially not--\\
'''Mac:''' ''DON'T SAY IT!!''\\
'''Bloo:''' Fine.
** Prince Charming [[DisguisedInDrag acting as Bloo's girlfriend "Prissy"]], and continuing to hit on Frankie ''in costume'' with Dylan sitting ''right next to them''.
-->'''Bloo:''' Princey- I mean Prissy, don't you and Frankie need to powder your noses?
-->'''Prince Charming:''' (In Falsetto) Why, yes, of course! (Lifts Frankie up and carries her to the restroom) Time for some girl talk!
* "Bloooooooo". From Bloo's {{Lampshad|eHanging}}ing of horror B-movie plots (and getting this particular one's premise exactly right) to this little gem:
--->'''Wilt''': Who ya gonna call?
--->'''Coco''': [[Franchise/{{Ghostbusters}} Co Co-co!]]
--->'''Wilt''': They've been out of business for years!
** The scene where Bloo [[TheManInTheMirrorTalksBack talks to his reflection in the mirror]]. First Mirror!Bloo sprouts a trumpet from his nose and plays Dixieland jazz, to which Bloo reacts by [[UnusuallyUninterestingSight muttering to himself about "feeling a little delusional"]]; then, when the others try and catch Bloo after mistaking him for a ghost, Mirror!Bloo yells at regular Bloo to "RUN FOR IT!"
* "The Bloo Superdude and the Magic Potato of Power".
** HerCodeNameWasMarySue has never been so downright hilarious. BEAR ARM GO!
** "Can't... break... free... too... many... muscles...."
** The ComicBook/TankGirl ShoutOut sequence.
** Coco doing a SexyWalk to get the attention of a giant chicken.
** The revelation that Bloo's story was a tall tale to cover up [[spoiler:ruining Mac's handheld gaming system]].
* "Crime after Crime":
** Frankie repeatedly fails at making "it," thanks to [[spoiler: people jumping on the bed]]. Gets funnier every time.
** Herriman gets a ransom letter for the carrots and reads it as having to come to the roof. What does it say when the audience can read it? "[[spoiler:[[IntelligibleUnintelligible Coco Coco Coco Coco Coco Coco Coco Coco Co]]]]" It's even a CutAndPasteNote, as if that would help somehow.
** Bloo trying to convince Mac to do bad stuff to get him into trouble, arguing that he's untouchable in Foster's: "What are they gonna do? [[YouAreGrounded Ground you?]] You don't live here! [[ComedicSpanking Spank you?]] They are not your parents! [[DeniedFoodAsPunishment Send you to bed without supper?]] You don't eat here! Don't you get it? You are invincible here!"
*** And Mac ends up using that immunity to do the most evil act he can imagine... [[spoiler:jumping on the bed!]]
*** And the follow-up to that: [[spoiler:Frankie goes into rage mode after Mac.]]
** Wilt trying to punish himself for Mr. Herriman's phony rules.
* Bloo's voice actor misread one of his lines in "Destination Imagination", which leads to this gem for older viewers.
--->'''Mr. Herriman''': Oh, Heavens! What's happening?!
--->'''Bloo''': You '''pissed him off''', that's what's happening!
* "Bloo's Brothers". Mac brings Bloo to show and tell one day. All of Mac's classmates think Bloo is awesome, so they all imagine weird clones of Bloo, only to leave them at Foster's. Bloo being Bloo, leads to this:
-->'''Bloo''': ''(Addressing his doubles)'' I am Bloo, and you are my minnions! Muhahahahahaha! ''(Clones laugh)'' Alone, you are singular knockoffs of a cool dude, but together we are as strong as any army! And I think we all know what we must do. ''([[{{Beat}} The Bloos blink and stare at each other]])'' That's right, we must [[MundaneMadeAwesome sing the Ice Charades theme song in one hundred-part harmony!!]]
-->''(Inside the community room, the other Bloos gather and sing.)''
-->'''Bloos:''' ''(Singing)'' Oh, Ice Charades, you're so icy and fun
-->Oh, Ice Charades, it's not the "capade" one
-->Oh, Ice Charades, every year comes to town
-->Oh, Ice Charades, get your money back if a skater falls...
-->'''Comically Deep Voiced Bloo:''' Dooooooooooooooowwwwwwwwwwwwwn.
-->'''Frankie''': (Marches in as the song ends) [[PunctuatedForEmphasis Holy. Guac. Amole.]]
** "Hi Mac. I see you've met Comically Deep-Voiced Bloo!"
** How does Mac ultimately solve the eventual SpotTheImposter problem, after narrowing it down to two Bloos? [[spoiler:Fake!Bloo gave a speech... that was ''too schmaltzy''.]]
* "The Big Cheese"
** '''[[PsychoStrings "I! Found! A! Carrot!"]]''' * stab* * stab*
* "Race For Your Life Mac and Bloo:" The titular buddies are racing each other to Foster's, but Bloo gets lost along the way. He seeks the help of a senior citizen sitting on a park bench, but it turns out the man is more than a little hard of hearing:
-->'''Bloo:''' Excuse me, could you tell me how to get to Foster's?
-->'''Old Man:''' Whazzat?
-->'''Bloo:''' Foster's! I need to get to Foster's!
--> '''Old Man:''' Flatsberg's, ya say?
--> '''Bloo:''' * getting annoyed* '''Foster's!''' Foster's Home for Imaginary Friends!!
-->'''Old Man:''' Flatsberg's Cone for Mackinary Hens?
--> '''Bloo:''' '''''Foster's Home For Imaginary Friends!!!'''''
--> '''Old Man:''' Flatsberg's Gnome Floor in Mackin' Harry's Pants?!
--> '''Bloo:''' '''[[PunctuatedForEmphasis Foster's!!! Home!!! For!!! Imaginary!!! Friends!!!]]'''
--> '''Old Man:''' Flatsberg's Foamy Foreign Asian Gary's Plans??!
--> '''Bloo:''' Foster's.
-->'''Old Man:''' Flatsberg's.
-->'''Bloo:''' Home!
--> '''Old Man:''' Dome!
--> '''Bloo:''' For!!
-->'''Old Man:''' Wharf!!
--> '''Bloo:''' Imaginary!!!
-->'''Old Man:''' Engaged Blueberry!!!
-->'''Bloo:''' '''FRIENDS!!!!'''
-->'''Old Man:''' '''''[[NoodleImplements Soup!!!!]]'''''
** Bloo's conversations with the clerk at the convenience store certainly qualifies.
* "Squeeze the Day"
** [[http://www.youtube.com/watch?v=L_IlsPypwZs It's hoooooooooooooot in Tooooopeeeeeeeeeeeekaaaaaaaaaaaaa.]]
** Later:
--> '''Bloo:''' I AM PIERRE ZESCHWANN. [[MakesJustAsMuchSenseInContext I PUT ZE DUCKS IN CRYSTAL POND.]]
--> '''Mac:''' What are you doing?
** Mac and Bloo are hilarious in this episode. They make the best prank call in history.
* "Good Wilt Hunting" has this hilarious line when they are heading to Japan-
-->'''Bloo''': [[Franchise/{{Godzilla}} GODZILLA!]] WILT'S CREATOR IS GODZILLA!
** The judge who was at Wilt's trial gives a long-winded and dramatic take on how Wilt become the town's folk hero [[MundaneMadeAwesome for cutting everyone's grass.]] What do they call him? The Lawn Ranger.
* "Store Wars"
** [[http://www.youtube.com/watch?v=nHlgEMy-BUc Bloo getting store clerks to massage him with a toy cactus.]]
** The IronicEcho at the end where Coco says it to Bloo and the epic ContinuityNod in a later episode where Mac stops him from doing it again at a flea market.
* This particular exchange from the camping episode:
-->'''Bloo:''' (fishing) I said I wanted bacon and eggs!
-->'''Mac:''' Okay, [[SarcasmMode let me just go back in time and prevent you from eating the ones we brought!]]
-->'''Bloo:''' [[SarcasmBlind You can do that?]]
** This is especially funny because Bloo's SarcasmBlind moment here is coming 3 episodes after he was specifically taught about sarcasm.
* The Funny Bunny Song in "World Wide Wabbit".
* This little gem, from Coco and Mac.
-->'''Coco:''' (In a sinister tone) Co-co, co-co co co.
-->'''Mac:''' Coco...I think if we did that, we'd go to jail.
* "Cuckoo for Coco Cards": Bloo saying [[http://www.youtube.com/watch?v=6nhJEqkAQWA "Come ooooooooon"]] till people give him their cards.
* "Goodbye to Bloo": The episode itself ended on a [[BittersweetEnding bittersweet note]]. The ending where basically the opening is reversed, reducing fans to tears, however there was MoodWhiplash, because beforehand there was a crowner when Cheese is revealed to have permanently moved into Foster's, followed by all the imaginary friends voicing their displeasure at this development.
* In "Cookie Dough" when Bloo is listing the positive attributes of his and Mac's cookies he states that they're free of dioxins. When no one knows what they are, he gives a detailed description of them then boils it down to "[[LaymansTerms They're bad for you.]]"
** When Bloo decides to sell merch relating to his cookies rather than the cookies themselves, we get this exchange where a customer calls him out on it:
--->'''Girl:''' Mister, can I have a cookie please?\\
'''Bloo:''' We don't sell cookies anymore.\\
'''Girl:''' You're dumb.
** Frankie, who practically worshipped Madame Foster's cookies growing up, now gets to eat as many as she wants whenever she wants. By the end of the episode, she's become [[BalloonBelly obese]] after gorging nonstop on cookies.
* "Joy ride with happy face? Never!"
* "Setting a President" has [[AttackOfThePoliticalAd all those slanderous, yet catchy, ads and songs]] Herriman and Bloo use to try and stop Frankie from winning the election. And this exchange at the debate:
--->'''Bloo:''' Herriman smells like poo!\\
'''Crowd:''' Hurray!\\
'''Herriman:''' But he's just mudslinging! ''([[LiteralMinded gets hit with mud]])'' I should've seen that coming.
* From "Make Believe It or Not":
** When we join Bloo and Mac the next day:
-->'''Bloo''': (putting on a fake mustache and sombrero) [[NoodleImplements Okay, so just act like you don't know me and the eclairs are ours!]]
** Bloo's complete overreaction to the power going out.
-->'''Bloo''': -we might as well just lay on the floor and die!
* The movie from "One False Movie". Coco's subtitles are French, but they're French for "I do not speak French!". And ''especially'' when [[spoiler:the movie gets (accidentally) taped over by Eduardo's favorite show, which is not revealed to anyone until the movie is being shown to the public]].
* "Bloo Done It". That whole episode is one big hilarity after another.
* "Beat with a Schtick". Between the HurricaneOfPuns, and the comical evilness of Madame Foster and Herriman, not to mention the ending, that whole episode is funny.
** When Bloo is trying to get himself expelled, he reveals he was responsible for spiking everyone's food with hot sauce and framed Jolly Buttons.
--->'''Herriman''': ([[MyGodWhatHaveIDone aghast]]) [[CrossesTheLineTwice We had him deported.]]\\
'''Bloo:''' I know. He still sends me post cards.\\
(Bloo pulls out letter written with magazine cutouts that says "[[foldercontrol]]

[[folder: I will get you ]]
** Bloo hires [[BigBrotherBully Terrance]] to take care of the new guy for him by promising Terrance that Mac will basically be his punching bag and ButtMonkey. Even after Terrance agrees to help, Bloo tries to sweeten the deal- to Mac's displeasure.
--->'''Bloo''': Really? Cuz if you're not sure, we can sweeten the deal. How about a few extra noogies?\\
'''Mac''': Bloo! He said he'd do it!\\
'''Bloo''': ''(pulls out a pink t-shirt with white print in the middle)'' How about this t-shirt? We can make him wear this t-shirt I made.\\
'''Mac''': ''(reading the t-shirt)'' "Mac Like-A The Potty!"?!
* Pretty much all of "My So-Called Wife", especially Coco's crash course in etiquette and Bloo's sarcasm lessons.
-->'''Mr. Herriman:''' (''after Coco jumps in her soup bowl'') Oh, good heavens, woman! [[ComicallyMissingThePoint That's the fine china!]]
** "Simon says laugh at that guy as he walks away!" ''(Everybody Laughs)''
* The [[UsefulNotes/MacysThanksgivingDayParade Macy's Parade]] RickRoll is equal parts funny and awesome.
* "Infernal Slumber"
** Mac and Bloo whisper-fighting when Mac ruin's Bloo's prank.
** Mac and friends' attempts to convince Terrance that he's dreaming after walking in on their party, complete with Bloo [[MindScrew petting a log and talking backwards]].
** Cheese yelling "Shut up, doggie" while preventing Terrence from yelling to wake up Mac's mother.
** TheStinger has Terrence claim to his and Mac's mother that the damage done to their apartment room's ceiling was caused by Mac, Bloo, and some imaginary friends. Once he finishes saying this and is certain he'll be believed, his mother then bluntly informs Terrence that he is grounded.
* Herriman's melodramatic flashback in "The Trouble With Scribbles."
-->'''Herriman:''' The autumn of [[AntiquatedLinguistics nineteen-hundred and eighty-four]] was cold... and cruel.\\
(Fade to sepia-toned outside shot of the building. A door is heard opening and millions of scribbles come flying out of the window)\\
(Cut to Herriman, Madame Foster and young Frankie floating amidst the swarm)\\
'''Young Frankie:''' [[BabyTalk Sowwie, Mistew Hewiman]].\\
(Cut back to present)\\
'''Frankie:''' (annoyed) I said I was [[ExactWords sowwie]].\\
'''Herriman:''' "Sowwie" doesn't make up for the fact that we were forced to take up residence in the unicorn stables for 46 days.\\
'''Madame Foster:''' (Passing through, gleefully) It was like camping.
* In "Sweet Stench of Success", after having enough of being a celebrity, Bloo starts singing songs saying how he doesn't want to do this anymore in his performances. The last one before his friends come get him is a slow, somber one, [[MoodWhiplash and then...]]
-->'''Wilt:''' ''(Walking on stage in a toothbrush costume, singing happily)'' Let me brighten your smile!\\
'''Eduardo:''' ''(Doing the same thing as a bar of soap)'' I wash the bad times away!\\
'''Coco:''' ''(As a tube of toothpaste)'' Cococo co-co co-co!\\
'''Mac:''' ''(As dental floss)'' And I help prevent tooth decay!
* "Seeing Red"
** Terrence's dream of Mac and Bloo having to scream over his snoring to spell out to him that he can only win by outnumbering them.
** Terrence creating an anthropomorphic pizza imaginary friend and promptly [[CrossesTheLineTwice eating it alive as it screams in agony]].
** While still kind of mean, the pranks Bloo plays on Red are pretty hysterical, especially when he tricks him into getting stung by imaginary bee friends by telling him to dance for honey and telling him that the imaginary pony friends love being told they're adorable, which results in the pony friends headbutting Red away.
* Quite a lot of the shorts are gut-bustingly hilarious.
** "Badvertisement" has Bloo shoot a commercial for Foster's where he's just full of himself and makes everyone else look like a fool (one highlight is Mr. Herriman being tricked into saying that he is stupid). After the commercial ends, Bloo asks the others what they think. They simply glare at him.
** "Petrified Pet" has Bloo find a mysterious rock while digging and is informed by Phineus B. Vurm that it is a rare fossil. Bloo decides to make the rock his friend and does things like share his toothbrush with it and cradle it in his arms while sitting in a rocking chair. Frankie later tells Bloo that what he's holding is actually petrified poo, much to his disgust. Bloo then turns to Phineus, who shrugs and says "Just because I'm a genius doesn't mean I know everything."
** "Cranks a Lot" consists of Mac being tempted by Bloo into crank calling Mr. Herriman by blowing raspberries over the phone. Mr. Herriman tries to retaliate, only for Frankie to hear him razzing on the other end. Eventually, Mr. Herriman responds to another flatulent noise heard from the phone by going on a tirade about how childish this action is. It then turns out that he was unknowingly talking to Madame Foster this time, who shrugs and says to the audience "So I'm a bit gassy."
** In "Birthday Cake Bloos", Mr. Herriman sternly tells Bloo that he can't touch his birthday cake until it's time for the party. Mr. Herriman ends up sleeping while guarding the cake and Frankie and Bloo decide to teach him a lesson by hiding the cake and tricking Herriman into thinking that he ate the cake. Right when Frankie reveals that the cake wasn't eaten, Madame Foster is then seen eating the cake, gloating that [[ScrewTheRulesIMakeThem she can't be punished because she owns the place]].
* "Duchess of Wails"
** When Duchess expresses her disapproval towards the dress Madame Foster sewed her, she tosses it off and snaps that she'd rather go naked. Madame Foster begs her not to do so, which is especially hilarious because she screams "Not again", implying that Duchess actually went naked before!
** The Applebees assuming that all of Duchess' blunt insults are meant to be jokes.
** Terrence apparently thinks that Singapore is [[ArtisticLicenseGeography in Wisconsin]].
*** It gets even funnier when even Bloo himself believes Terrence's interpretation later on.
* Quite a lot of the ChristmasEpisode "A Lost Claus"
** Bloo tries to scare Mr. Herriman into giving him more than just one present for Christmas by [[YetAnotherChristmasCarol pretending to be the ghosts from]] ''Literature/AChristmasCarol'', but he completely gets it wrong. For instance, he gets Jacob Marley confused with Music/BobMarley, the Ghost of Christmas Present becomes the Ghost of ''A'' Christmas Present, and for the Ghost of Christmas Future, Bloo dresses up as a scary-looking robot and tells Herriman that if he doesn't do as the ghosts have warned, it will result in a BadFuture.
** Mac tries to visit a MallSanta to assuage his concerns about the existence of Santa Claus, but finds that the Mall Santa is Coco. It then turns out that the children actually believe Coco to be the real Santa, but what really sells the scene is what her employer says after Mac unintentionally exposes her.
-->'''Coco's Boss:''' You lied to me! You're not the real Santa! You're fired!
** Mac sees a lot of signs indicating that Santa is real, such as Eduardo being free from the chimney and getting the underwear he asked Santa to give him as proof that he exists, but what really makes Mac conclude that Santa's real is finding that Bloo got coal for being naughty!
** Bloo swearing revenge against Santa for giving him coal.
* TheStinger to "I Only Have Surprise for You" has Madame Foster try to explain to Eduardo and the clown imaginary friend that Artie isn't real, but when they see her Artie costume, they reach the incorrect conclusion that Artie is dead, resulting in Eduardo running away screaming and the clown going on a tirade about how sick and deranged he perceives Foster's to be.
* In "Bad Dare Day", Mac and Bloo at one point dare each other to do things to Sloppy Moe, which eventually escalates to Mac daring Bloo to ''marry'' Sloppy Moe.
