Metafictional endings

the last paragraph/chunk thing in "Happy Endings" is about its own ending. it says, "so much for endings." it then goes on to talk about how boring plots are. it ends by saying that stories should focus on the reasons and not the results. it adds to the story, because that is the theme it is trying to push, but instead of just saying that with the story it openly says it in a little summary at the end.
