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
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.

Skippy: I feel airsick. Urp!
Slappy: Dissolve to the next scene, quick!
Iris out already, please!

Miner: What brings you to these parts, sonny?
Yakko: The player with the controller in their hands, if I'm not mistaken.

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!

*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.
