- If you thought Cheese's first episode was a blast, this troper could hardly contain her giggles in "Cheese-A-Go-Go" whenever the imaginary friend went on his "Gotta Go!" tangent.
- Anytime when Mac is having a sugar rush. Especially in Partying is Such Sweet Soiree.
- Try watching Cheese's first episode with a straight face. It's impossible.
Bloo: I don't even know you anymore.
- "Hot rod flames!" "Bunnies!!" They eventually compromise on flaming bunnies.
Mac: Shut up. At least the bunnies are on fire.
Cheese: I like cereal.Eduardo: I like potatoes.(Repeat ad nauseum)
- The fact that the music for when Cheese screams is just banging randomly on a toy piano.
- Cheese's conversation with Eduardo.
Bloo: Oh, Mac, you're the best kid an imaginary friend could ever- (he notices Cheese) WILL YOU GET THAT THING AWAY FROM ME??!!
- Bloo is delighted that Mac offers to build the toy car but then notices Cheese is still in the room with his toy horse.
- At the start of "Busted", Bloo is suffering from a Potty Emergency, 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 "A bust this big needs ample support!"
- World Wide Wabbit
Frankie: Mr. Funny Bun-... I mean, Mr. Herriman isn't taking interviews, NOW GET OUT OF HERE!
- All of the viral video parodies in "World Wide Wabbit." Yes, including- nay, especially the one with the dubbed-in farts.
- Everyone trying to hide the news of Mr. Herriman's fame from him, with it barely working. That is until the news crew shows up.
Reporter: But we're live. (door slammed)
Frankie & Mac: LIVE?! (with Bloo having a face that says it all)
Herriman: WHAT IS THE MEANING OF THIS?!?! WHO IS RESPONSIBLE FOR THIS?!
- Then when Herriman finds out and completely flips out (even causing the house to shake), Mac, Bloo, and Frankie all blame each-other.
Bloo: (pointing to Frankie) Her!
Frankie: (pointing to Mac) Him!
Mac: (''pointing to Bloo) Him!!
All three: Me?! Are you crazy?!
Bloo: Mac's the one who taped it!!
Mac: Yeah, but I wanted to erase it! Frankie's the one who burned it to disc!
Frankie: Yeah, but Bloo's the one who uploaded the file to the internet!!
- "Frankie My Dear":
Bloo: Oh, no! He's using lines!Prince Charming: Is it hot in here...or is it just you?Pizza Guy: Good ones!
- Prince Charming's introdution, where he drops enough cheesy pick-up lines to give The Fresh Prince a run for his money.
"Oh, silly me. A spoon can't pick up a steak!"
- ORLANDO BLOO. The part where he's trying to eat the steak is the funniest thing to ever come out of Foster's.
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": 47, yes. I mean, 2.
- Let's also not forget how Frankie and "Orlando" dated for 20 years.
"Orlando": So then after the pep rally, I went up to her and said, "Hey, babe, I'm a gazillionaire."
- How did "Orlando" and Frankie meet? Apparently, at a pep rally at Billionaire School.
Bloo: Especially not—
- 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".
Mac: DON'T SAY IT!!
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!
- Prince Charming acting as Bloo's girlfriend "Prissy", and continuing to hit on Frankie in costume with Dylan sitting right next to them.
- "Bloooooooo". From Bloo's Lampshading of horror B-movie plots (and getting this particular one's premise exactly right) to this little gem:
- Wilt: Who ya gonna call?Coco: Co Co-co!Wilt: They've been out of business for years!
- The scene where Bloo 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 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!"
- It was actually even funnier than that - Mirror!Bloo says "Run, Bloo! Run!" in the same tone as Obi Wan Kenobi's voice saying "Run, Luke! Run! in "A New Hope."
- "The Bloo Superdude and the Magic Potato of Power".
- Her Code Name Was "Mary Sue" has never been so downright hilarious. BEAR ARM GO!
- "Can't... break... free... too... many... muscles...."
- The Tank Girl Shout-Out sequence.
- Coco doing a Sexy Walk to get the attention of a giant chicken.
- The revelation that Bloo's story was a tall tale to cover up ruining Mac's handheld gaming system.
- "Crime after Crime":
- Frankie repeatedly fails at making "it," thanks to 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? "Coco Coco Coco Coco Coco Coco Coco Coco Co" It's even a Cut-and-Paste Note, 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? Ground you? You don't live here! Spank you? They are not your parents! 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... jumping on the bed!
- And the follow-up to that: 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. (The Bloos blink and stare at each other) That's right, we must 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 funOh, Ice Charades, it's not the "capade" oneOh, Ice Charades, every year comes to townOh, Ice Charades, get your money back if a skater falls...Comically Deep Voiced Bloo: Dooooooooooooooowwwwwwwwwwwwwn.Frankie: (Marches in as the song ends) Holy. Guac. Amole.
- "Hi Mac. I see you've met Comically Deep-Voiced Bloo!"
- How does Mac ultimately solve the eventual Spot the Imposter problem, after narrowing it down to two Bloos? Fake!Bloo gave a speech... that was too schmaltzy.
- "The Big Cheese"
- "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!

- Bloo's conversations with the clerk at the convenience store certainly qualifies.
- "Squeeze the Day"Bloo: I AM PIERRE ZESCHWANN. I PUT ZE DUCKS IN CRYSTAL POND.I AM PIERRE'S EVIL BROTHER! I STEAL ZE DUCKS FROM CRYSTAL POND!I AM PIERRE'S THIRD COUSIN! I HAVE ZE EAR ON ZE SIDE OF MY FACE!I AM PIERRE'S GIRLFRIEND! *KISSING NOISES*Mac: What are you doing?

- "Store Wars"
- Bloo getting store clerks to massage him with a toy cactus.
- RIP OFF ARTIST! *kick* OW MY SHIN!!
- The Ironic Echo at the end where Coco says it to Bloo and the epic Continuity Nod 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!Bloo: You can do that?
- This is especially funny because Bloo's Sarcasm-Blind 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 "Come ooooooooon" till people give him their cards.
- "Goodbye to Bloo": The episode itself ended on a bittersweet note. The ending where basically the opening is reversed, reducing fans to tears, however there was Mood Whiplash, 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 "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 obese after gorging nonstop on cookies.
- "Joy ride with happy face? Never!"
- "Setting a President" has 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!
Herriman: But he's just mudslinging! (gets hit with mud) I should've seen that coming.
- From "Make Believe It or Not":
Bloo: (putting on a fake mustache and sombrero) Okay, so just act like you don't know me and the eclairs are ours!
- When we join Bloo and Mac the next day:
Bloo: -we might as well just lay on the floor and die!
- Bloo's complete overreaction to the power going out.
- The movie from "One False Movie". Coco's subtitles are French, but they're French for "I do not speak French!". And especially when 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 Hurricane of Puns, 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.
- Bloo hires Terrance to take care of the new guy for him by promising Terrance that Mac will basically be his punching bag and Butt-Monkey. 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! That's the fine china!
- "Simon says laugh at that guy as he walks away!" (Everybody Laughs)

- 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 petting a log and talking backwards.
- Cheese yelling "Shut up, doggie" while preventing Terrence from yelling to wake up Mac's mother.
- The Stinger 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 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: Sowwie, Mistew Hewiman.
(Cut back to present)
Frankie: (annoyed) I said I was 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, 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 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 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 in Wisconsin.
- It gets even funnier when even Bloo himself believes Terrence's interpretation later on.
- Quite a lot of the Christmas Episode "A Lost Claus"
Coco's Boss: You lied to me! You're not the real Santa! You're fired!
- Bloo tries to scare Mr. Herriman into giving him more than just one present for Christmas by pretending to be the ghosts from A Christmas Carol, but he completely gets it wrong. For instance, he gets Jacob Marley confused with Bob Marley, 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 Bad Future.
- Mac tries to visit a Mall Santa 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.
- 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.
- The Stinger 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.
- "Bus The Two Of Us" has Wilt rushing to get to Coco before Frankie does - he enters the five's bedroom and holds the door open for Frankie, only to slam it in her face the second she enters. Poor guy can't help his politeness.
