Brick Joke/Anime and Manga/Puella Magi Madoka Magica

In Madoka Magica, you'll be wondering where the Deconstruction elements are laid in, but it will take about two and a half episodes for it to be noticed. That is within itself a Brick Joke, created by the fanbase.

No surprise when Episode 10 comes around do the elements of other Episodes suddenly become very familiar, for good reason. This list of Brick Jokes/Call Backs from earlier Episodes may be spoileriffic if read under the right context, so beware of potential spoilers.

Episode 1
Episode 1 in its entirety is a Brick Joke: almost everything that happens has some important relation to the plot later on.
 * The opening Credits Running Sequence has black-and-white Astral Checkerboard Decor, which looks extremely out of place when compared to other episodes. Later Episodes showcase the Witches with Astral Checkerboard Decor.
 * The second sequence shows Homura fighting off against a powerful floating...thing. Homura in later Episodes tells Madoka that a something powerful is coming soon.
 * A seemingly out-of-place sequence shows Madoka looking in several directions, and then randomly waking up, which looks like a Shout-Out to Sayonara Zetsubo Sensei.

 * Episode 1's Witch has copious amounts of flowers and scissors stylized like a "secret garden" Eldritch Location, but Mami defeats this Witch. Episode 3 has Level Ate, complete with knives and cakes.

Episode 2

 * Mami Tomoe's name is stylized in a strange way on the plaque at the apartment she lives in. Her name is written like "巴マミ", and "Tomoe" is also the same name of a famous female samurai named Tomoe Gozen.
 * Mami talks about the role of the Magical Girl, but there's a lot of unexplained questions, like how the Witches are formed at all. It does not help that Mami's VA is the same as an infamous Exposition Fairy.
 * In one part Sayaka asks something along the lines of
 * Remember the teacup Mami summoned after defeating Gertrud in Episode 2? It reappears in Episode 3 Also, Homura said that "this is the fate of a magical girl", while it shows  a Grief Seed.

Episode 3

 * Before Mami arrives at the room that has Charlotte, she says that to celebrate Madoka becoming a magical girl, they should eat cake.

Episode 10
