* If you try entering a vehicle from the driver's side that already has a driver in it, they'll notice and make fun of you.
-->'''Lisa''': Despite my age, I'm the one driving here.
-->'''Chief Wiggum''': What do you think this is, Grand Theft Auto? Get out there....
-->'''Homer''': Hee hee! You're dumber than me!
* In the opening cutscene:
-->'''Krusty''': Hey hey kids! I'm endorsing a new cola and [[NoodleIncident this one]] [[BlatantLies isn't poisonous]] ''to anybody!''
-->'''Announcer''': That we know of.
* This gem:
--> '''Bart''': I've gotta get the new Bonestorm game or I'll be as uncool as Milhouse!
--> '''Milhouse''': I'm standing right here, Bart.
* In Level 2, as Bart is collecting illegal fireworks to join the recent fad, he talks to Moe.
--> '''Moe''': Sorry, Bart. I can't sell booze to a minor. It ain't right.
--> '''Bart''': I'm here to buy fireworks.
--> '''Moe''': Oh, hell yeah!
* Pretty much all of Ralph's dialogue in the races.
--> '''Apu''': Hey, aren't you the boy who nearly drowned in nacho cheese?
--> '''Ralph''': I was in the newspaper!
* In Level 1, one of Homer's missions is to return things to Ned, one of them is a cooler he gave to Barney:
--> '''Homer''': [[NoodleIncident Uh, remember that cooler I gave you for your birthday?]] Well, Flanders wants it back
--> '''Barney''': Now what will I use for a toilet?!?!?
* When buying the Plow King from Barney:
--> '''Homer''': Barney, can I borrow the Plow King?
--> '''Barney''': Take what you want, you sexy leprechaun, just don't shoot me with that dart gun! Oooooooh....
--> '''Homer''': Whatever.
* Mr. Burns initially thinks Homer is a former business partner he murdered: "Wow, that was really...wow."
* In Level 3, Lisa asks Wiggum how many strikes they have on Snake.
-->'''Wiggum:''' Uh, no strikes. But that's only because I'm a very, ''very'' bad cop.
** In the same conversation, he reveals that the police department can't afford a disguise like an eyepatch- he's being paid in potato chip coupons!
** And at the end of the mission, Lisa thanks Wiggum's directions to help find Bart by saying he ''is'' a good cop. Wiggum [[DismissingACompliment deflects the compliment]], and Lisa confirms that, yes, she didn't mean it.
* At the end of level 5, Bart and Apu learn that [[spoiler: Buzz Cola is going to send everyone into a murderous frenzy to boost the rating of a reality tv show.]] Bart's thoughts?
--> '''Apu''': We must prevent the [[spoiler: aliens]] from putting laser guns in the hands of cola drunk towns people.
--> '''Bart''': Why? [[ComedicSociopathy That sounds hilarious!]] [[ComicallyMissingThePoint I'd watch that show.]]
--> '''Apu''': *Facepalms* I tell you what, you're a bad little boy.
** The level after, he eventually goes on trying to get help in confronting the matter, with Apu turning chicken and denying that he ever spoke English. After the final mission in Level 6, Bart goes right back to wishing for the worst to happen due to how awesome it would be to him.
* Snake happens to dislike obscenity. On two occasions (by different characters, he immediately complies on the ''threat'' of it.
-->'''Apu:''' I will be forced to use... profanity.
-->'''Homer:''' I will flip you the bird.
* After accomplishing Mission 2 of Level 3, you can [[VideoGameCrueltyPotential knock Milhouse into the river]] (although if you do this beforehand [[VideoGameCrueltyPunishment it will prevent you from finishing the mission]]).
* A meta example - Radical Entertainment's devs took an odd glee in having Homer kick Marge around, but were told not to do it around Creator/MattGroening. When Matt was given a chance to test out the game, the first thing he did? [[NotSoDifferent Had Homer literally kick Marge from the home down to the Kwik-E-Mart]].
* Why did Dr. Nick's monkeys escape from his lab? "Because have I tortured them horribly, silly!"
