This is my show, and I'll do what I like with it. Cue the carollers!
Kogoro: With his super speed, Kogoro can don his helmet faster than the eye can perceive!
Keroro: He's talking as if someone else is narrating!
Giroro: Yes!! I was almost fooled by that square balloon!!
— Keroro Gunsou, Encounter 51: Target: The Hinata Household
Pit: Am I ever going to get to the top of this tower?
Viridi: I warned you before we got here that it was a long way up.
Pit: Yeah, but this place is so huge, we even had a loading screen back there.
Viridi: Shhh, they're going to hear you! We're not supposed to talk about that!
— Kid Icarus: Uprising, "Chapter 19: The Lightning Chariot"
What are we talking here? Mini-Boss? Final Boss?
— Pit, Kid Icarus: Uprising, "Chapter 2: Magnus and the Dark Lord"
End of first sequence, and fade to black!
— Ed, Ed, Edd n Eddy, "An Ed in the Bush"
An iris-in would be appropriate, don't you think? *iris-in to black* Thank you.
— Edd, Ed, Edd n Eddy, "Here's Mud in Your Ed"
Hey! Yeah, you! I'm down here, busting my ass, while you sit on yours, watching me jump around? How is that fair?!
Skippy: I feel airsick. Urp!
Slappy: Dissolve to the next scene, quick!
Iris out already, please!
— The Warners, Animaniacs
Miner: What brings you to these parts, sonny?
Yakko: The player with the controller in their hands, if I'm not mistaken.
— Animaniacs: The Great Edgar Hunt (Ye Old West soundstage)
The truth was a burning green crack through my brain. Weapon statistics hanging in the air, glimpsed out of the corner of my eye. Endless repetition of the act of shooting, time slowing down to show off my moves. The paranoid feel of someone controlling my every step. I was in a computer game. Funny as Hell, it was the most horrible thing I could think of.
What is this mysterious enigma of mystery that has been mentioned about 15 times in the story without really telling us what it is?
— Mille, Ilivais X, Day 11: Darkened Holy Knight
Skippy: But Aunt Slappy, those were cartoons, and this is real life!
Slappy: *Addressing the viewer* Don't tell him. He might crack.
— Animaniacs (which has quite a lot of this trope, if you couldn't already tell)
Ed: I should have all the feeling back in my feet after this word from our sponsors, Double D.
Edd: Cursed broadcast commercialism!
— Ed, Edd n Eddy (which also has quite a lot of this trope), "If It Smells Like an Ed"
Being self-aware sure is hilarious!
— Alpha 5, Truncated Power Rangers
*Headset attached to Trucy.*
Trucy: "Attached?" I'm not some kind of robot, Apollo!
— Apollo Justice: Ace Attorney, Turnabout Serenade
With a wink, Sonic vanished into the crowd, probably off to find some other girl to dance with. The thought made Amy burn, especially considering she was stuck with Link-
Link: Hey! I can hear the narration, you know!
What the heck is Link talking about?
— Super Paper Mario X, Chapter 60
Ed: I am a sassy cat and so full of sass. If you don't like it, you can kiss my-
Edd: Ed, if you finish that sentence, the show'll get cancelled in a second.
Karen: Who is that girl dancing with Prince Coco?
Rin: It's Cinderella, the title character.
Karen: I already know that, but I still have to say my lines.
— Yes! Pretty Cure 5, the Cinderella episode. They're both playing the 'Wicked' Stepsisters, btw.
Swerve: Oi—ship's genius—what happens if I press this button?
Brainstorm: Don't press it. Did you press it? Swerve? Tell me you didn't press it.
Swerve: Course I didn't press it... but what if I had pressed it?
Brainstorm: You'd have activated an abstract weapon— a meta bomb.
Swerve: A what what?
Brainstorm: A metafictional bomb. It blows a hole in the fourth wall.
Swerve: Me no understand.
Brainstorm: Basically, it makes the enemy think they're characters in someone else's narrative. Robbed of agency, they lose the will to fight. I'm still working on it.
Swerve: Guess what? I pressed it. Nothing happened.
Rewind: I didn't see you press it...
Swerve: Yeah, it must have happened off-panel.
Rewind: What does that mean?
Swerve: I have no idea.
Professor Ian Duncan: Abed, how many fingers am I holding up, and more importantly, are they still made of clay?
Abed Nadir: Three, and I told you, it's not clay. We're silicone bodies with ball-and-socket armatures.
Manabe: "What's wrong, Kotoura? Why the glum face?"
Kotoura: "Shut up, you pervert."
