* When Grandpa and the boys are introduced, the very first scene is of him sneaking up on them in bed, and poking their noses with a twig to see if they can wake up and intercept it. Colt and Rocky manage it perfectly, but Tum-Tum just rubs his nose like it was an itch. Mori then tries poking the bag of candy sitting next to him, and Tum-Tum intercepts the twig the ''moment'' it touches the plastic bag.
* Idiotic surfer villain is holding up a convenience store at gunpoint:
--> "Now open up that cash register, 'fore I have to get nasty. (Beeper goes off) Excuse me, sir? Could we please use your telephone?"
** Even before that, their introduction has them ogling a centerfold... of a surfboard.
* When the henchmen take the kids from their house, Colt tries to aim a kick at Toru Tanaka's stomach, only to have his leg caught and end up hanging upside down by his ankle.
--> "Would you like me to drive?"
*
-->'''Colt''': Rocky, these ninjas have '''guns'''.
-->'''Rocky''': Hey, if they have guns, they're not ninjas.
-->'''Colt''': Yeah, and if they fire off the guns anyway the police'll hear.
-->'''Tum Tum''': [[SarcasmMode Oh, that's reassuring.]]
* The boys trick Marcus and Hammer into drinking a large soda filled with ''laxative''.
-->'''Tum Tum:''' ''(pretending to drink)'' Hmm this stuff is good!\\
'''Hammer:''' Give me that!
* Before the goons barge into the house, Emily tries to call Rocky through the tin can, but Tum Tum picks it up first. We have this dialogue:
-->'''Tum Tum:''' ''(in a lovey-dovey tone)'' Hey, it's Emily. She wants to talk to Rocky.\\
'''Rocky:''' ''(doing his homework)'' Tell her I'm busy.\\
'''Tum Tum:''' He says, he loves you.\\
''[Colt laughs. Rocky rolls his eyes with a sigh, and went over to the tin-can phone.]''\\
'''Tum Tum:''' Rocky loves Emily!
* Colt witnesses the goons breaking into the house and locking up the babysitter. He quickly retreats to his and his brothers' room, where we get this exchange.
-->'''Colt''': Guys, I've got some good news and some bad news. The good news is... the delivery guy just creamed the babysitter with a pizza.
-->'''Rocky and Tum-Tum''': Awesome!
-->'''Colt''': The bad news is... they're carrying guns.
-->''(Rocky and Tum Tum get OhCrap faces)''
* "I hope you saved some pizza for us!"
* Right after Marcus finish taking a "major dump", Tum-Tum rams him on his stomach with a mounted warthog's head. Twice. When Marcus fell on the floor out cold, the trophy landed on his stomach, making it look like it's bursting out of him.
** Colt and Rocky get the drop on Hammer, who's also suffering from their LaxativePrank, and just when they're about to strike:
--->'''Hammer:''' Not the stomach! Not the stomach!\\
[''Rocky and Colt shrug, then elbow him in the face, knocking him on his butt'']\\
'''Hammer:''' Thanks... [''passes out'']
* Before the basketball game, the lead bully makes an unfunny crack at Colt's nickname, then after a moment of silence orders his lackeys (and the other kids) to laugh. They comply.
* Rocky traps the three goons inside the renovated room with Colt hiding inside. The goons try to find Colt, who sneaks up behind them and making them hit each other. At one point, Colt made Fester and Marcus punch Hammer in the nose. Later, they try to get out, when they pull the door harder, Rocky cuts the rope, and Colt makes them trip.
* When the boys get cornered by some ninja henchmen on Snyder's ship, they get some makeshift weapons from random tools and debris and prepare to fight, only for the lead goon to do some fancy flourishes with his nunchucks and smack his subordinates behind him several times.
* ''Knuckle Up.''
** Mori tests his grandsons by softly whacking at them with a stick and seeing if they can intercept the blow when they come outside in the morning. All of them are used to that kind of test, and Rocky and Colt pass it easily. When its Tum-Tum's turn, he merely wears a hardhat outside and doesn't even try.
** At the end of the pizza parlor fight, J.J. orders his cronies to "get those kids." The goons (who've just received a CurbStompBattle from said kids) immediately [[KnowWhenToFoldEm run away]] as jaunty music plays.
** The brothers clean up the pizza parlors counters by sliding Tum-Tum across the counter like a rag to capture all of the garbage and then shove it into the trash can waiting at the end. Cool accidentally shoves Tum-Tum into the garbage can as well, causing his flailing legs to stick out as he demands to be helped out.
** The brothers eavesdrop on the villains' conversation by unscrewing a pipe, sticking a hose up through the sink and listening with their ears to the other end of the hose. Then Harding turns on the water, drenching Colt right after he snatches the hose from Rocky.
** After Jo kisses Tum-Tum on the head, [[GirlsHaveCooties he complains that he just took a bath.]]
** Jo draws the peace sign on Tum-Tum's forehead, but he mishears the word as "peas" and complains that he hates peas.
** After Jack and his entire army of goons get beaten up while trying to retrieve some incriminating evidence, Jack tells J.J. that they need to hire professionals and asks if he knows any. J.J. says that he knows a good lawyer, and Jack angrily yells that he's talking about mercenaries. When J.J. confirms that he does know some mercenaries, Jack orders him to get them "on the horn." After a long, confused pause, J.J. starts honking their car's horn, causing Jack to angrily yell that he means the telephone.
** During the fight at the landfill, a {{Mook}} grabs the MacGuffin and yells "I got it!" Rocky knocks him down, causing the disc to go flying away, and the thug says "I don't got it."
** One poor {{Mook}} gets hit in the face with a pot, squirted in the eyes with hot sauce, kicked in the groin, and tricked into grabbing or sitting on multiple cactus plants when he gets overconfident about being able to defeat Tum-Tum. The scene is played for glorious slapstick effect.
** As Colt (who has a crush on Jo) talks about how girls can distract a ninja's concentration, he crashes his bike due to not watching the road.
** Every moment where Rocky (who's barely old enough to shave) is driving during the CarChase is hilarious.
*** Rocky tries to argue that he has experience from a video game he played, even though he is shown repeatedly crashing while playing that video game earlier.
*** Rocky's brothers tell him this isn't like driving in the arcade. [[ComicallyMissingThePoint He enthusiastically agrees, saying "Think of all the quarters I'll save this way."]]
*** Tum-Tum spends most of the ride convinced that he's about to die in a prolonged SayYourPrayers scene (saying that he'll never drink and drive, and then that he'll never drive period). He has to be physically forced to get back into the car when they need to leave later on.
*** As they drive away from the ghost town, Rocky hits a very old tree and tries to claim that it "came out of nowhere."
--> '''Colt:''' Yeah, about a hundred years ago.
* In ''High Noon at Mega Mountain'':
** "You couldn't hit an elephant in the butt with a bazooka!"
** The Jamaican guy saying, "Ey, man! Check this ooot."
