* Ooblar checks out Jimmy's toaster satellite, and a piece of toast pops out of it.
-->'''Ooblar:''' ''Hello! ({{beat}}) What galaxy are you from?''\\
'''King Goobot:''' Ooblar...\\
'''Ooblar:''' ''Where is your leader?''\\
'''King Goobot:''' Ooblar, stop it. It's ''toast''.\\
'''Ooblar:''' Oh... ''({{beat}})'' [[ComicallyMissingThePoint Hello, Toast]]! I greatly admire your ship.
* Tough JerkJock Nick ScreamsLikeALittleGirl upon encountering Poultra and running away.
-->'''Cindy''': My hero?\\
'''Sheen''': Okay, we need another plan. Probably a Nick-less one.
--> ''(Pan to Nick whimpering in a corner.)''
* This dialogue:
-->'''Nick:''' That is the StupidestThingIveEverHeard!
-->'''Sheen:''' No, ''this'' is the stupidest thing you've ever heard: blah-blah-blah-blah-gooble-dooble!
* The "Self-Destruct sequence".
--> ''(Ooblar takes a small metal square from Goddard.)''
--> '''Jimmy:''' (over speaker phone) Danger! Danger! You have initiated Self-Destruct Sequence Alpha.
--> '''Ooblar:''' Ooh, that's my bad. Back in you go.
--> ''(Reaches to put the plate back.)''
--> '''Jimmy:''' Self-Destruct Sequence is now engaged.
--> '''Ooblar:''' Nonononono! I put it back in! You understand me!?
--> '''Jimmy:''' This unit will yield a 50-megaton nuclear blast in exactly 10 seconds.
--> '''Ooblar:''' [[OhCrap That's not good!]]
--> '''Jimmy:''' Please clear a 30 square mile area, thank you and have a nice day.
--> ''(A yellow smiley face on a spring pops out and opens up to reveal a timer: 10...9...8...)''
--> '''Ooblar:''' (screams) No! Bad dog! (screams) [[IWantMyMommy Mother!]]
* The ritual that the Yolkians make the parents do to summon Poultra is... the chicken dance.
--> '''Nick:''' They're making our parents dance so ''lame''!
--> '''Carl:''' No, my dad really dances like that.
--> ''[[AmazinglyEmbarrassingParents (Cut to Carl's dad doing disco and Egyptian-style dances.)]]''
* [[ToiletHumor "I'm peeing! In the shower!"]]
** "I'm still doing it! Go go go!"
** Even better is Jimmy and Carl's [[{{Squick}} reaction]] in the in-character commentary of the GENIUS, SHEENIUS, OR INBETWEENIUS special.
--->'''Jimmy and Carl:''' Ewwww!\\
'''Sheen:''' [[DefensiveWhat What?!]] It's perfectly natural!
* "We were gonna see who could eat the most cotton candy... [[PyrrhicVictory and I won]]!"
* Jimmy's ship crashes on his house in the opening sequence:
--> '''Hugh:''' Well, what do you know. [[OhNoNotAgain The chimney fell off again]].
* [[ItMakesSenseInContext NOT]] [[OhCrap TINY!]]
* While everyone else's rockets blast away, [[ButtMonkey Carl is still stuck on the ground trying to make his fly.]]
--> '''Carl:''' Come on you stupid butterfly with your - Wuh-a-a-h!
* Carl's show-and-tell. Also Sheen's BigNo when he realises Cindy tricked him into taking the Ultra Lord figure out of its box, removing its value. [[ActuallyPrettyFunny Even Jimmy snickers at how over-the-top Sheen is reacting.]]
* When the kids encounter the meteor shower, Jimmy calls for evasive action. Goddard pops an umbrella out of his head.
* After all the parents disappear, the kids make the most of having no rules. A kid starts dancing in mismatched clothes, singing:
--> ''My clothes don't match, my clothes don't match, I'm out in public and my clothes don't match!''
* Despite occurring in an otherwise pretty dark scene, a brief moment when the parents are being abducted shows one of the fathers (later revealed to be Cindy’s) was apparently in the middle of reading a newspaper while sitting on the toilet.
* This gem at the climax:
-->'''Sheen''': ♪Ultra Lord is not afraid of chickens! He is not afraid--♪ ''(The aliens fire at the ship, throwing everyone off balance)'' ♪Okay, he may be a little bit afraid of chickens!♪
* Sheen fainting over meeting an actor dressed as Ultra Lord in Retroland.
-->'''Ultra Lord''': Is this kid with anyone?
* Moments after the above example, the llama gives Carl an annoyed look after he touches it.
* Jimmy's parents drinking the [[GassHole burping soda]].
-->'''Hugh''': Well, at least it's coming out of the attic, not the basement!
** Culminating into this:
---> '''Judy''': ''(spots the Neutron symbol on the can)'' [[FullNameUltimatum JAMES ISAAC NEUTRO]]-*Loud belch*
** Which [[ActuallyPrettyFunny even Judy ends up laughing over]] while Jimmy and Carl fall over laughing themselves silly.
* This exchange from show-and-tell, which underwent MemeticMutation:
-->'''Sheen''': This is ULTRA-LORD!!
-->'''Mrs. Fowl''': Sheen, this is the 7th week in a row you've shown Ultra Lord in class.
* This gem on the asteroid:
-->'''Carl''': And before my mom was [[{{Malaproper}} inducted]] by aliens, she would rub my tummy and she'd sing "nani, nani, nani--"
-->'''Nick''': What?!
-->'''Carl''': Nothing!
* In the video Jimmy made that the aliens are watching, Jimmy points to parents in a photograph, but he mistakenly calls his dad "mom" and vice versa.
* When Hugh tries to take off his mind-control helmet:
-->'''Hugh''': Intruder Alert!! Intruder Alert!! Big fiery flying intruder Alert!!
-->'''Jimmy''': Dad, No, no! No! Shh!
-->'''Hugh''': ''(quacking)''
-->'''Sheen''': Jimmy, your dad's like a mind-controlled duck man.
* Jimmy asks Goddard for options after being grounded. One of the ones Goddard comes up with is: “Build Goddard a female poodle.” Jimmy, exasperated, tells him to take it seriously.
* In one teaser for the film:
-->'''Jimmy''': Does anybody know where we can get a ''lot'' of raw plutonium?
-->'''Disclaimer''': Creator/ParamountPictures and Creator/{{Nickelodeon}} [[DontTryThisAtHome do not advocate the pre-teen use of plutonium]].
-->'''Jimmy''': Whoops.
