Torg:Nothing Can Save Us Now! Zoe: What was that about? Torg: It's a classic cliché! In this type of situation, when someone says "Nothing can save us now," it's followed by someone showing up to save us. Zoe: You mean like "It can't get any worse"? K'z'k the Soul Collector:(suddenly appears) Hi kids!
Often done in Chrono Redux in part to make fun of the comic itself, but also to make fun of the game "Chrono Trigger" when these sorts of things happens in the game. These are usually brought up by Chrono in internal monologues because he's mute.

On this page, just as a major mystery about spacetrawler construction is about to be cleared up...
Mr. Zorilla: You're going to change to another storyline aren't you. Nogg: Meanwhile, back in Kppfing. Mr. Zorilla: I hate you. [On the next page, Mr. Zorilla has forced Nogg out of the car.] Nogg: Okay okay! I'll continue telling you about how spacetrawlers are made. Mr. Zorilla: Alright. You can get back in.
Homestuck is utterly rife with visual and verbal callbacks. Late in Act 5, Doc Scratch calls attention to the fact that these keep happening, and names the phenomenon "circumstantial simultaneity" (as opposed to mere temporal simultaneity). Then, in Act 6, Dirk Strider lampshades it again:
TT: I feel like you've said something like that before. TT: Different statements, but in that exact syntax. [...] TT: That actually sounds familiar too. TT: Are you sure you haven't said something like that before?
In Episode Two of Space Kid , Pizmo points out to Dr. Conquest the unnecessary complexity of his plot to destroy a city with a giant robot squid.
Ménage à 3 isn't prone to such self-awareness, but does lampshade Gary's Extreme Doormat status in strip #795 (September 24, 2013, marginally NSFW); "It's like he has no will of his own." For an added twist, this recognition also immediately reinforces Gary's Clueless Chick Magnet status, as he becomes a target for seduction — by a rather scary dominatrix.
