In "Shopping Spree", Mung, Chowder and Shnitzel go to a mall and spend all of the money in Truffle's money box while she is ill. Not only can they not afford all the stuff they bought, but they can't afford the animation and are consequently reduced to their respective voice actors: Dwight Schultz, Nicky Jones, John DiMaggio and Tara Strong. So what do they do? They have a car wash. 
Turn on captions while "The Blackout" is on and pay attention to what the weirdos say.
The tail end of the bluenana episode was pretty hilarious...
Baby Bluenana: (Cough) Mother..? Is that... you? Take me away from theses horrible people! The mother then proceeds to call Panini and Chowder monsters and runs away crying as everyone still has a WTF? face on them.
"Pepper spray? That sounds delicious...(gets sprayed in the face) I WAS WRONG! I WAS HORRIBLY HORRIBLY WRONG!"
This exchange from the Marmalade episode:
Panini: Chowder, get over here.
Chowder: But...can't I have more than one friend who's a girl?
Panini: No. Don't test me, Chowder.
Chowder: ...What flavor lip gloss are you wearing?
Panini: Smackdown. Now get over here.
Chowder: Uh, I think I'd rather stay with Strawbarbleberry...
"Hey Mung! I'm gonna make you pee your pants!"
Mung on the Meaches: "They broke every bone in my body! They even ate my hair!"
After Mung gives up trying to build a schmingerbread house he says "Knishmas is ruined, and it's all Schnitzel's fault."
The "At Your Service" episode, especially the part where Endive tells Panini to "put on some Celine" as Mung and Chowder rid Endive's pool of bugs.
Mung's failed attempt to save Truffles during a flood.
"This isn't supposed to sink! It's MADE OUT OF FISH!"
When Panini makes Chowder hold her hand in "Banned from the Stand". Panini's reaction seals it:
The episode where they're making the singing beans, and Mung adds a huge gold clock on a chain, 'For Flava'. That is quite possibly the smartest joke ever made on a children's show.
In the episode where Mung needed to get a Queen Meach for a meach pie, when Chowder, Mung, and Schnitzel are dressed as a mariachi band. The soldier meaches are not impressed and chase them out, and Chowder yells, "NO ME GUSTA!!"
Mung Daal: No! Don't let them tear your arms off! That only makes them angry!
Mung Daal: I've got to do something! (turns on the car radio)
At the end of the episode "Brain Grub":
Mung Daal. It's a long story. Chowder. Does it have pirates in it?
The scene in the Apprentice Scouts when Gazpacho yells at Ceviche for throwing up.
"There's no time for barfing! You've got a badge to earn! What do you think, we're just gonna sit in the bushes and barf all day? Fat chance, pal! FAT CHANCE!"
The scene in the episode "The Heist" where Schniztel, in a desperate attempt to keep Endive unaware there are Sugar Sapphires under her house, kisses her. The people's Reactive Continuous Scream was gold!
Chowder's many attempts to ward off Panini in "Chowder's Girlfriend". Especially the one where he dons a moustache as a disguise.
Chowder (wearing a fake moustache): Why hello Panini. I have a message for you from Chowder. Who I am not.
Panini: Uh huh.
Chowder: Chowder has moved far away and can not be your boyfriend.
Panini: Where did he move to?
Chowder: Uh, down the street to the next city.
Chowder (deadpan): He's dead. Chowder's dead.
Panini: Want a cookie Chowder?
Chowder: Would I!- Aw man!
Comedy Gold! Relationship Comedy!
Chowder and Gazpacho: ...
When Schnitzel goes up to the mic to tell his jokes, he starts, sees Mung, Chowder, and Truffles, and runs through the brick wall.
From "Panini for President":
Chowder: I'm not listening to Gorgonzola. I was just hanging around with him all day because he was giving me food. He's ma' friend.
Panini: Gorgonzola is not your friend. He's, like, a villain or something.
Gorgonzola: (dressed as the phantom of the opera): How's it going Mr. President?
Chowder: Ah! A villain!
Cop: Did somebody say villain?
Gorgonzola: You'll never take me alive, copper! (runs away)
Alot of "Paint the Town".
"Look at me I'm crazy box head man!"
In "My Big Fat Stinky Wedding" Chowder has to sneak into Kimchi's wedding located inside an alligator. When you think that he would use a wrench to knock out Identical Stranger Porridge, but instead trades the wrench for Porridge's glasses. Porridge even wears the wrench in place of his glasses and plays the violin poorly as a result. Chowder then places the glasses on the gator's eyes and uses the altered perspective to somehow enter the gator's nose.
Earlier, Chowder tries to think of a plan to stop the wedding. One montage later, he constructs a Trojan Horse-like thing, and it turns out to be a coin-operated horsey ride!
