Superboy Prime from ‘Legion’ Prompts Laughs, LOLrage
The recent "Legion of 3 Worlds" by Geoff Johns ended with (SPOILER) Superboy Prime returning to Earth-Prime (a.k.a. our reality, kind of) where holes up his basement with actual DC Comics like "Final Crisis," forces his family to bring him grilled cheese sandwiches, breaks the fourth wall to yell at the reader, and then gets online and starts angrily trolling the DC Comics online forums.
In short, it was one of the most brilliant twists I've seen in mainstream comics in some time, and was only made better by the fact that the thread he was reading actually exists, and that the actual message board posters being parodied then started angrily trolling the online forums, thus making the circle complete and giving the comic an almost Morrisonian metatextualism.
The greater internet, naturally, responded by referencing Keyboard Cat.
