Later on, when she kills Genovese, she screams Tunk you!, which was alluded to earlier when Dave's friends ask him to spread around a new curse word that they want to become to Spear Counterpart to the c-word. And then whilst Hit-Girl is killing all of the mobsters, Kick-Ass is just stood there utterly stunned at how quickly the word has caught on.
The whole subplot where Dave pretends to be Katie's Camp Gay best friend is treated in more detail here, and it's very funny(especially Dave's reaction compared to his reaction in the movie).
From Kick-Ass 2: the superhero Battle Guy is relating his origins of how his parents had been killed and eaten before his eyes when Kick-Ass identifies him and says out loud that he met his mother at the grocery that morning.
From Kick-Ass 3: Dave, mourning at his father's grave in an attempt to evoke imagery of Bruce Wayne at his parents grave, with Todd taking photos as they try to replicate specific shots from the Batman comics.
Chris' so-called ninja training in the interquel Hit-Girl: at first it seems serious, but then his teacher sends him to retrieve a blue lotus flower on a mountain because he's seen it in Batman Begins and starts talking with a colleague about how much money they can swindle out of Chris...
Later Chris wises up and leaves, deciding to hire a bodyguard... And the ninjas are complaining he won't hire anyone of them, with their boss whining that he had promised his wife a vacation to Las Vegas.
From the interquel Hit-Girl, our Tyke Bomb has covered Kick-Ass by gunning down about a dozen between mob bosses and enforcers and he protests she had agreed to not kill anyone. Her answer?
In Kick-Ass 2, this line from Marcus as he reveals he found Mindy's weapon cache.
"Props for getting an AK-47 in a teddy bear, by the way."
The Motherfucker's first supercrime in Hit-Girl: he enters a store to rob it and murder everyone with a laser while getting on camera and then on the internet. He murders the owner with the laser, but then:
Motherfucker: "What the hell's up with this thing? Why isn't it firing?"
Hood 2: "It's the XM-25, Chris. I told you... It takes 30 seconds to recharge.
It ends with Insect-Man and Doctor Gravity accidentally stopping Chris' escape... And then debating if they should call the police and save him or not.
Red Mist and Kick-Ass in the Mist Mobile for the first time. You hear Gnarl's Barkley's "Crazy" and see Kick-Ass head bobbing to it at first and then a few seconds later we see Red Mist and him both dancing to it.
"That's right! We're superheroes! You love us!"
"That's a fucking bazooka, you dumb-ass!"
Dave thinking about what he'll never do due to dying. "Like learn to drive or see what me and Katie's kids would look like or find out what happened on LOST."
Then, there's his reaction when the henchman apparently fires the thing but actually is getting shot by Kick-Ass using a hoverpack. He has this delighted grin on his face, but comments "Strangest-sounding bazooka I've ever heard."
Dave, who's been playing up the gay card to be close to Katie. After the Kick-Ass reveal and courtship, the gang is in the comic shop comparing Kick-Ass and Red Mist. Katie: (paraphrased from memory) "Kick-Ass is much hotter. If he were here, I'd totally fuck his brains out." Dave: "Hey, isn't that new Kate Hudson movie out today? Want to go to the theater?" Katie: "Hell yes." Gilligan Cut to both of them screwing in the alley.
In case you didn't notice, the whole bazooka scene. It starts with Hit-Girl cornered behind the kitchen's table and without ammo but still dangerous due her aim with knives, so Frank's bodyguard says he's gonna recover the bazooka. The other henchmen are wondering if it's not overkill, Hit-Girl cries "The bazooka?!", then there's Chris reaction at him grabbing the bazooka after declaring he had everything under control... This troper choked due too much laughter...
The guy who "received" Hit Girl's knives just prior to the bazooka sequence is a whole load of funny. It starts with him being the last guy in a hallway full of mooks that Hit Girl brutally takes out. When she runs out of ammo, she chucks her gun at his head, grabs his gun and tries to shoot him while he's on the ground - only he was also out of ammo. Then, after she's forced to retreat, he's too scared to face her even with fresh backup - so he's given a big gun and sent out against her at gun point where he randomly unloads his clip at the cupboard she's behind. When that runs out of ammo, he's got the dumbest nervous grin on his face....and then finds two knives in his chest.
During the torture scene as Todd and Marty watch via internet, Marty tells Todd to look at Erika holding onto him in fear, and Todd giving him a thumbs up.
Dave's face when the woman in Rasul's apartment starts rubbing her tits together.
The opening, in which a man in a bird-like costume leaps off a building to fly. The heroic music builds, people clap in amazement... and then he smashes into a cab and dies.
Dave: That's not me, by the way. That's some Armenian guy with a history of mental health problems.
Chris, as the Red Mist, smokes a joint while driving in the Mist Mobile with Kick Ass. Kick Ass's face when he sees Chris smoking one makes it even funnier.
